Yes, thanks for chiming in and clarifying Jared! I did indeed make a typo.

Agreed with Eb, with the slight correction that the code is in $MESA_DIR/star/test_suite not $MESA_DIR/star/private/...

Specifically check out the function gamma1_integral which is called by data_for_extra_history_columns in $MESA_DIR/star/test_suite/pisn/src/run_star_extras.f90

Cheers,

Hello Jalena,

"the pressure weighted integral of
Gamma1-4/3 (integral_gamma1)" is not a default history_column, but you can add it for yourself by adding an additional history column in the run_star_extras.f90. Both the PISN and PPISN test_suites in $MESA_DIR/star/private/test_suite calculate this quantity, so you should be able to save some work by copying it from one of these test cases into your local directory.

Dear all,

I am trying to see if some of my massive models end as pair-instability
SNs and I have found that in that case you should monitor central value
of (Gamma1 - 4/3) and the point when the pressure weighted integral of
Gamma1-4/3 (integral_gamma1) drops under zero.

Could you please let me know which values in output files correspond to
the above mentioned? Is it shock_gamma1, gamma1_min.., and I don't seem
to find integral_gamma1 in history-column.list..

Many thanks,
Jelena
