[Mesa-users] Science Fair

[Earl Bellinger]

Dear Karan,

One thing you could try is to see is how the metallicity of the stars
change as they evolve. You could look in the history file for the
abundances of different elements and plot them as a function of the age of
the star. You can then try to understand what physics is involved in
causing these abundances to change over time.

Best regards,
Earl
