I'll probably fix that in code for the next version, just improving a bit the code that replaces the default star.
I see. I have also done the same thing with some of the other stars myself, including Betelgeuse and Epsilon Eridani. Maybe I will send my improved scripts to you if you want to use them as well. I don't think I made any significant improvements with Betelgeuse (I just wanted to see what it would look like as a supernova ) but I made several improvements to Eps Eri, so that its distance, radius, mass, rotation period, and age are all exactly correct (except for age which is only known approximately).
