It was my understanding that the 26- or 27-million-year periodicity idea was discredited some time ago as not being statistically significant. In any case, no “Nemesis” red- or brown-dwarf companion star (presumably in a highly elliptical orbit) has ever been found, and if one existed within even 10 lightyears of the sun, WISE would have found it. --Rob ______________________________________________
