[Mesa-users] No He burning for tutorial M=0.81 star

[Aaron Dotter]

Hi Rich,

You mentioned two plots in your email but didn’t send them.  Would you?
You can save plots from pgstar as PNG files.  Perhaps that will help us to
answer your question.

Maybe you can also explain in more detail what you were expecting to see at
the “horizontal branch stage”.

Finally, it would help if you could save a model close to the end of the
evolution that you were following so that anyone who tries your inlist
doesn’t have to start from the beginning.

Thanks,
Aaron
