[Mesa-users] Inquiry about Units in profile.data

[Meng Sun]

Hi Guo,

Hello from the same research institute!

In general, these physical quantities are in cgs units unless specifically
noted in $MESA_DIR/star/defaults/profile_columns.list.

I think you are referring to a very recent version of MESA, r24.08.1, as I
couldn't find 'log_rate_r_c12_ag_o16' as an available default profile
column (I have r22.05.1 on my PC). The reason I tried to look for it is
that it seems to be in a dimensionless unit - i.e., the ratio of the
nuclear reaction rate of C12 to O16. I recommend grepping
'log_rate_r_c12_ag_o16' through your MESA directory to double-check.

Hope this helps!

Cheers,
