Star Colors

July 29th, 2008

Phil Plait at Bad Astronomy addresses the question of why are there no green stars.   It’s a nice post and brings together astronomy and biology in interesting ways, and reminds me of the posts I did a couple of months ago for a friend who’d just sold a story about life on a world orbiting an M star and wanted to know some things about how it would look there.

At first I thought everything would look red, but decided that was not quite right.   Those posts have some very good links as references on this issue, on both the astrophysical and biological sides and I expect to refer back to them in the future.

And then discussing these issues with some fellow astronomers we figured out that if there weren’t exactly green stars, there are at least green star-like objects in the sky anyway.
