Re: Re : [meteorite-list] Chondrule formation mechanism (Info Please)
Hi, Rob, Pete, Ed, List, Rob wrote: The iron is formed in the cores of all stars. Nuclearly speaking it is the stablest of all elements (lowest binding energy per neucleon...or is it the highest, can't remember) I hate it when I have to dive into thick books more suited for anchors than reading but here goes... Not all stars form iron. The one thing that determines the entire life of a star is how fat it is. An anorexic star is just another Jupiter or Super-Jupiter. At somewhere around 12-13 times the mass of Jupiter, a star starts to burn deuterium and we can really call it a star. Stars burn hydrogen. Deuterium is just regular hydrogen toting a neutron in its backpack. Slap two of them together and you get helium (and a lot of excess energy). All stars, regardless of size, start out as hydrogen burners. The D-D chain is the easiest reaction to get started but there are lots of routes from hydrogen to helium that use other elements for their intermediate stages (called proton-proton reactions) and I'm not going to type them all out. So there. Fast forward a few billion years. A star will use up all of its hydrogen. About the time it's running on fumes, the helium ash left over from burning up all your hydrogen like there was no tomorrow has sunk to the core and is getting hotter and denser. Eventually, that helium in the core starts to burn. Now, the star is a helium-burner. This nuclear heat generated in the helium-burning core causes the star to expand and expand and expand into a big gasball many times its original size: a red giant. A star has to be at least half the mass of our Sun to do this. Our Sun will do this... in another 4-5 billion years. Goodbye, Solar System. A helium burner this big will evolve carbon12-burning. Again there are many possible reactions, but most of the carbon is turned directly into oxygen16. As things get hotter, we get neon20, magnesium24, silicon28, each one is produced by slapping (fusing) a helium nucleus into the last one, hence the jump by 4, 4, 4, 4... Now, a nice little star like our Sun will just end up as a bright superdense carbon12 diamond a few thousand miles across, called a white dwarf. But if the mass of a star is 1.4 times the mass of the Sun or greater, it will just go crazy with this fusion stuff. The end result is a star with an onion structure: an outer shell of hydrogen burning surrounding a shell of helium burning, surrounding a shell of carbon burning, surrounding a shell of neon burning, surrounding a shell of oxygen burning, surrounding a shell of silicon burning, surrounding a core where the really weird stuff goes on. Silicon burning should proceed until iron is built, but it doesn't happen. By this time the heat, pressure and energies involved are so great that the LIGHT produced by the fusion becomes more powerful and energetic than all the other players! As soon as a nuclei heavier than silicon is produced, a photon on steroids knocks it apart, slaps it down, and kicks it around until it gives up those extra nucleons and crawls off in all its silicon shabbiness. Iron may get formed but it doesn't last. And, yes, iron has the HIGHEST binding energy per nucleon and a high electric charge barrier, but the real problem is that the photons produced by creating it are energetic enough to rip it apart. If you want to picture the true violence of a stellar interior, try imagining a beam of light powerful enough to smash atoms... OK, they're super-gamma rays, but they're still just light. The iron (and nickel) core forms inside the silicon burning shell as some of the iron continually being formed escapes from the cycle of birth and instant photo-death by dripping down out of sight in the core as it forms. But the iron core is doomed. Eventually the mass and pressure of the star's outer layers collapse the core and compress it so much that the star crushes its own core hard enough to squeeze the electrons in its atoms into the protons in those atoms and turn them into neutrons. The body of the star is blown away and there's a 20-mile lump of neutrons left behind, almost pure neutronium with a thin crust of hot diamond and some silicon, perhaps. This is how a universe that started out as nothing but hydrogen, helium, and a smidge of deuterium got so interesting, because core collapse triggers those nasty supernovae. Supernovae come in two varieties: Regular Really Nasty, and Extra Special Super Nasty, sometimes boringly called Type I and Type II. The supernova explosion is triggered by the collapse of the iron core (I just can't take it any more!) Oddly, core collapse is very, very orderly*, not the mad chaos you'd think would happen, not at all. Entropy is constant and the core is in perfect equilibrium the whole milliseconds long duration of its collapse. Collapse starts when the core reaches a density of about 1,000,000,000 gm/cm3. Nothing can stop the collapse until the density reaches

Greg, I sold the world's ugliest meteorite early in my collecting career soon after I bought it from Haag... Mills. So please don't send me another contestant, I felt guilty enough selling that one to a friend for the $1/g I paid for it. As for the gentleman's agreement to keep ads to once per week per person that Adam incessantly refers to, I never agreed to such a thing and I doubt the majority of subscribers give a hoot about that as well. I'm more tired of hearing Adam complain about that agreement than I am about the extra ads. That agreement is not on the general list policies either: http://www.meteoritecentral.com/mailing_list.shtml General List Policies: 1. Posts need to relate -in some way- to meteorites 2.

Do not post -major advertisement- emails to the list - include a 'sale' link 9. If you are posting a URL for a sale, include 'SALE' in the subject box I do notice many Hupe ads (glad it's not a very big family :) which get a little repetitive sometimes, and some that tend to skirt the line of policy number 8, but that is a rather nebulous rule. I'm not bothered by ads since I can remember the time when I would eagerly await a snail mail catalog a few times per year from one of the few dealers out there, then hurry through the list to call in my order before someone else called first. Those were the days when any meteorite offering was a good one, as I wanted a piece of every type. I remember, and now I appreciate all the ads, which occasionally offer something of interest for me.

If somebody were to take cuts to the front of one of these long lines and damage the air with a methane release right in front of you, most would consider this pretty rude. at disneyworld they have something known as a fast pass (or is it a speed pass) allowing you to cut infront of the line and wait 5 minutes to get on your favorite ride instead of an hour. i'd say that most list members (including the owner) would agree that given the spectacular nature of the photos Mike linked he was just using a fast pass. _ Find a local pizza place, music store, museum and more then map the best route! http://local.live.com?FORM=MGA001 __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] UK Residents Shaken by Mystery Explosions, Bright Flash of Light
http://www.herts-essex-news.co.uk/news/mercury/hertfordshire_mercury/2006/10/20/residents%20shaken%20by%20mystery%20explosions.lpf Residents shaken by mystery 'explosions' Herfordshire Mercury News (United Kingdom) October 20, 2006 TWO mysterious 'explosions' in the early hours woke up residents across the Mercury patch, set off car and burglar alarms and knocked items from window sills. The bangs roused bemused householders from their slumber at around 3am and 3.30am on Monday. Residents in Stanstead Abbotts reported hearing the 'explosions' and it is thought some people in Ware heard the bangs. They emanated, however, several miles away in Hoddesdon, where several people saw a bright flash. Yesterday (Thursday, 19 October), as staff at Hailey Hall School in Hailey examined their seismograph to see if it recorded the incident, the cause of the bangs remained shrouded in mystery. Theories abounded, with fireworks, a power station, guns and even supersonic aircraft blamed for disrupting the night peace and setting off alarms. Others thought an 'unexploded bomb' found in a Great Amwell garden on Sunday had gone off - but that turned out to be an anchor! Among those who saw a flash was Alison Gable, 33, of Granville Gardens, Hoddesdon. She said: I'd had a bad dream and was sitting at the front window so I saw and heard everything. I saw a flash. It was brighter than lightning. Three seconds after, I heard the noise. That was dead on 3.30am. I stayed up afterwards waiting to see if the emergency services would turn up because it was that loud. There was a boom but the house didn't shake. I did though! It was far too loud and powerful for fireworks. Stanstead Abbotts resident Russell King said: I heard them here and wondered at the time if a farmer was using explosives to remove old tree stumps or excavating - but why at night? Mark Offredi, of the Roselands estate in Hoddedon, said: My whole house was woken up by that explosion. I have friends in Stanstead Abbotts who head the noise and thought it might have been some sort of gun. After visiting my nan's house a few doors away - she was away at the time - we noticed that many items that were on window sills had fallen to the floor. Also woken by the noise were Patricia and Ronald Day, of Stanstead Road, Hoddesdon. She said: We thought it was something exploding or a great big bomb going off. Police received two calls about the sounds but were not called to any incident. The fire service received no calls about them. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Focusing a Laser on Martian Rocks and Soils (LIBS on MSL)
http://www.psrd.hawaii.edu/Oct06/libs.html Instrumets of Cosmochemistry LIBS: Remote Chemical Analysis Planetary Science Research Discoveries Written by Linda M. V. Martel Hawai'i Institute of Geophysics and Planetology In this series of articles, Instruments of Cosmochemistry, PSRD highlights the essential tools and amazing technology used by talented scientists seeking to unravel how the solar system formed. You will find information on how the instruments work as well as how they are helping new discoveries come to light.lightbulb Laboratory Caliber Instrument on a Rover Laser-induced breakdown spectroscopy (LIBS) is an active remote sensing technique used for the rapid characterization of elemental compositions of materials. Used for years in laboratory and industry applications, it will make its debut performance on rocks and soils on another planetary surface in 2010 as part of the ChemCam instrument package onboard NASA's Mars Science Laboratory (MSL) rover scheduled for a 2009 launch to Mars. A combined Raman-LIBS is also planned to be part of the Pasteur instrument payload on the ExoMars rover mission planned by the European Space Agency for a 2011 launch. In preparation for use on Mars, a team of scientists at Los Alamos National Laboratory, Roger Wiens, Justin Thompson, James Barefield, David Vaniman, Sam Clegg, and colleague Horton Newsom (Institute of Meteoritics at the University of New Mexico) have tested the LIBS technique on two Martian meteorites and a terrestrial analog rock. Their work confirms that LIBS is capable of determining even subtle differences in rock types from a stand-off distance of 5.4 meters. This high-quality remote sensing on the surface of Mars is exactly what's needed to push the state-of-the-art of cosmochemical investigations as we prepare for follow-up Mars sample return missions.

How LIBS Works Laser-induced breakdown spectroscopy (LIBS) uses a high power pulsed laser, focused on the target, to provide more than a megawatt of power on a small spot less than a millimeter diameter for a few billionths of a second. The target rock can be up to 13 meters away from the instrument (otherwise known as the stand-off distance). Each laser pulse vaporizes thin layers of the target rock--a process known as laser ablation--producing a hot spark or plasma. This supersonically expanding plasma glows with electronically excited ions, atoms, and small molecules from the target rock (see image below.) [frame of LIBS plasma movie] http://www.psrd.hawaii.edu/Oct06/LIBS_LosAlamos_plasma.mov Click on the movie frame to view a QuickTime movie in a new window. This picture shows the glowing LIBS plasma produced in air during a laboratory test where the laser was five meters away from the rock. The high-temperature ablated material breaks down into electronically excited atoms and ions, giving off light when they decay back to lower energy levels. The light emitted by the plasma can be collected and analyzed through spectrometers to resolve the characteristic emission lines of the elements that are present in the target rock. Original source: http://libs.lanl.gov/LIBS_movies.html. Note that the apparent wandering of the plasma position on the rock is due to motion of the rock during the test. There is no positional instability of the laser relative to the spark size. The plasma light is collected by a reflecting telescope and directed through a fiber-optic cable to spectrometers, which resolve and measure the elemental emission lines in the plasma spectrum. In a typical analysis, the spectra from multiple pulses (for example 75 to 100 pulses) are averaged for greater statistical accuracy into one final spectrum for the analysis spot. The LIBS technique yields detailed, quantitative information on compositions of the elements (high and low atomic numbers), including some minor and trace elements, that are present in the target rock. This information is obtained very quickly, within minutes, and will allow scientists to identify rocks on the surface of Mars that are of greatest interest and may be chosen for further investigation by instruments that require physical contact or for collection. Why LIBS is an outstanding tool for planetary surface analyses: * no sample preparation is required * operates at a stand-off distance (typically 2-13 meters), which permits remote analysis of inaccessible rocks (perhaps up on cliff) * the laser removes dust from target surfaces, again without the need to

[meteorite-list] Re: One ad per week rule
Hi Bob and List, In regards to the once a week rule, I follow it because the consensus reported to Art that there were too many advertisements. Art then made an official post to this forum that the people have spoken and the only one ad per week rule was made. I have no problem, whatsoever with dealers or collectors announcing exciting finds and posting links to pictures, I enjoy viewing them. I feel the line is crossed when somebody posts links to images and then tries to disguise an ad when they posted two ads already in the same week. 95% of the time I say nothing when I see this happen but if the rule is abused for weeks I may feel compelled to comment on it. If everybody posted three advertisements a week then members would start to complain loudly as before. My brother, most dealers and I wait once a week to run advertisements and announce new meteorites. In other words, we wait until the appropriate time and batch all of our announcements into a single post. I don't think Art is asking too much to limit it to a single ad per week regardless of how fantastic a new offering might be. If it can't wait a week, then there is a problem. My brother and I have several exciting new meteorites to report but will limit the announcements to once a week. On the other hand, if I cut into something fantastic and get excited, I may post a link to an image but will not turn it into an ad if I already used up the quota. By the way, Mikes new iron is very nice! Too bad I don't collect irons since I live a couple hundred feet away from a salt water body otherwise I would find Mike's offering price reasonable.

If somebody were to take cuts to the front of one of these long lines and damage the air with a methane release right in front of you, most would consider this pretty rude. at disneyworld they have something known as a fast pass (or is it a speed pass) allowing you to cut infront of the line and wait 5 minutes to get on your favorite ride instead of an hour. i'd say that most list members (including the owner) would agree that given the spectacular nature of the photos Mike linked he was just using a fast pass.

[meteorite-list] park forest outing
Hi list.Just a plug tomorrow on our park forest outing.Me and a couple other guys will be heading down to pf to do some hunting and showing where the main impacts fell.If anyone wants to join us feel free to do so.The weather is supposed to be in the low 50's and partly sunny.So come if you can or want to.I really believe there is more to be found. steve arnold,chicago Steve Arnold,Chicago,USA!!

RE: [meteorite-list] Re: One ad per week rule
Yes , it is annoying when someone advertises too much. Yet, habitual abusers may well be filterd, even by an incompetent such as I. I must admit, that most of the list are honourable enough to classifly their wares under the subject AD: To me, when I have no cash, that's a good indication to ignore. Seriously, guys (and gals), we have enough going on to avoid the controversy of who's advertising too much. I appreciate the big boys behaving themselves on the Ad front, I really do, but don't often read the ads anyway. It'd be far better for noobs if once a week a list of which ebay names went out vs the dealer names. I'm still putting my list together after a year. The big boys, its easy but some of the little guys are much les frequent yet I trust them implicitly. My thoughts only (*posted at 2am and really tired.

By the way, Mikes new iron is very nice! Too bad I don't collect irons since I live a couple hundred feet away from a salt water body otherwise I would find Mike's offering price reasonable. Adam, you are a well known dealer. any post you make with pics showing some awsome new material would automatically be assumed as something that can be had for purchase. even if mike didnt say that the iron slices were for sale i would ahve still emailed him asking to buy a piece. if you just cut into a 50kg orientated lunar that fell in your front yard even *I* wouldnt fault you for breaking the once a week rule if you posted a link to photos with a 'call me if you want some' addition at the end of the post - and you know how much i love to agrue with the hupes ;) BTW, dont let saltwater scare you away from irons - i used to be the same way. get yourself an acrylic dessicator cabinet - they are pretty good for display purposes and keep all of your rusters safe from even the florida environment.

Re: Re : [meteorite-list] Chondrule formation mechanism (Info Please)
I shall be forever grateful that I saved this post. Having read an exerpt of it in Ed G's reply, I returned to the original and am forced to reiterate a previous effusive, unabashed compliment of Sterling's effective translation into laymans terms of the most simple of processes in the universe. Simple in the sense of elemental. Sterling, I hope that you can make time in your life to preserve and collect these posts. I for one, and I realize, I may be in the minority, find such threads more than words like facinating can describe. Meteorites are the glue which keeps this group together but ultimate meaning motivates some of us to touch these sublime sources of understanding and imagine our origins among the stars. Who are we? Where did we come from? Where are we going? Astrophysics, Cosmology, Chemistry, Petrology, Relativity, Sp. relativity! Holy Cow! Hindu Metaphysics.

Nuclearly speaking it is the stablest of all elements (lowest binding energy per neucleon...or is it the highest, can't remember) I hate it when I have to dive into thick books more suited for anchors than reading but here goes... Not all stars form iron. The one thing that determines the entire life of a star is how fat it is. An anorexic star is just another Jupiter or Super-Jupiter. At somewhere around 12-13 times the mass of Jupiter, a star starts to burn deuterium and we can really call it a star. Stars burn hydrogen. Deuterium is just regular hydrogen toting a neutron in its backpack. Slap two of them together and you get helium (and a lot of excess energy). All stars, regardless of size, start out as hydrogen burners. The D-D chain is the easiest reaction to get started but there are lots of routes from hydrogen to helium that use other elements for their intermediate stages (called proton-proton reactions) and I'm not going to type them all out. So there. Fast forward a few billion years. A star will use up all of its hydrogen. About the time it's running on fumes, the helium ash left over from burning up all your hydrogen like there was no tomorrow has sunk to the core and is getting hotter and denser. Eventually, that helium in the core starts to burn. Now, the star is a helium-burner. This nuclear heat generated in the helium-burning core causes the star to expand and expand and expand into a big gasball many times its original size: a red giant. A star has to be at least half the mass of our Sun to do this. Our Sun will do this... in another 4-5 billion years. Goodbye, Solar System. A helium burner this big will evolve carbon12-burning. Again there are many possible reactions, but most of the carbon is turned directly into oxygen16. As things get hotter, we get neon20, magnesium24, silicon28, each one is produced by slapping (fusing) a helium nucleus into the last one, hence the jump by 4, 4, 4, 4... Now, a nice little star like our Sun will just end up as a bright superdense carbon12 diamond a few thousand miles across, called a white dwarf. But if the mass of a star is 1.4 times the mass of the Sun or greater, it will just go crazy with this fusion stuff. The end result is a star with an onion structure: an outer shell of hydrogen burning surrounding a shell of helium burning, surrounding a shell of carbon burning, surrounding a shell of neon burning, surrounding a shell of oxygen burning, surrounding a shell of silicon burning, surrounding a core where the really weird stuff goes on. Silicon burning should proceed until iron is built, but it doesn't happen. By this time the heat, pressure and energies involved are so great that the LIGHT produced by the fusion becomes more powerful and energetic than all the other players! As soon as a nuclei heavier than silicon is produced, a photon on steroids knocks it apart, slaps it down, and kicks it around until it gives up those extra nucleons and crawls off in all its silicon shabbiness. Iron may get formed but it doesn't last. And, yes, iron has the HIGHEST binding energy per nucleon and a high electric charge barrier, but the real problem is that the photons produced by creating it are energetic enough to rip it apart. If you want to picture the true violence of a stellar interior, try imagining a beam of light powerful enough to smash atoms... OK, they're super-gamma rays, but they're still just light. The iron (and nickel) core forms inside the silicon burning shell as some of the iron continually being formed escapes from the cycle of birth and instant photo-death by dripping down out of sight in the core as it forms. But the iron core is doomed. Eventually the
