[Mesa-users] Finding ZAMS

[Josiah Schwab]

Hi Thomas,

I don't see how it can function as global stop option for all masses.

Your plots nicely illustrate that a L ~= Lnuc definition of the ZAMS may
not always get what you want for your purposes.

Have you considered incorporating the central hydrogen mass fraction in
your definition?  For example, stopping when Xc = 0.69 (i.e. the start
value minus "a bit")?

Josiah

P.S.  Aaron Dotter's ZAMS definition in MIST is:

The ZAMS EEP is taken as the first point after the
H-burning luminosity exceeds 99.9% of the total
luminosity and before the central H mass fraction has
fallen below its initial value by 0.0015.
