You might be able to hack this effect:
Make a quad that's always oriented towards the camera. Give it a texture
that looks like the corona effect you're after (make sure it's transparency
around the edges of the corona). Scale the quad so the corona matches up
well with the geometry of the star/sun. Make sure the center of the quad (ie
the rotation point) is lined up w/ the center of the star/sun sphere. That
way, it should always look like the corona surrounds the sphere.
Let me know if this works.

ps. you could maybe even do some cooler effects with this method such as
solar flares, etc. Could be a lot of fun.

I'm sorry, no I don't. I haven't tried to figure that out yet. It looks
like the corona is done with some sort of lens flare algorithm, but I don't
have any experience with simulating that yet.
