Leos Ondra has
released this program. IMHO it is really a nice demonstration tool !
I recommend it to everyone who would like to get some feeling of the
relative time scales for the various phases of stellar evolution for stars
with different masses -- it is actually surprising (even if you longly know
that) to visualize how short the massive stars live, how short stars are
living as giants, and how fast they cross the HRD in critical phases. I'll
use it in class as soon as there's occasion.

The physics used by this program is based on work by G. Meynet et.al.
of Geneva Observatory. Fortran programs, results, and LaTeX articles related
