[Mesa-users] Detect zones with H fusion

Dear Anne, dear Josiah,

Many thanks for your very valuable inputs.

According to the following comment:
>So the specific energy generation rate by hydrogen burning in cell k of
>the model is

 >s% eps_nuc_categories(ipp, k) + s% eps_nuc_categories(icno, k)

if the sum of both energy generation rates is 0 for a cell k, is it right to assume that no hydrogen burning is taking place on it?

Kind regards,

Roque

Hi Roque,

And if you need to get even more specific (i.e. distinguish different
types of burning) there are different "categories".

See add_reaction_categories in profile_columns.list.  These have names
like pp, cno, etc.

If you're doing this in run_star_extras, there's eps_nuc_categories.
which is a (num_categories, nz) array.  You can get the category index
constants from chem_def.

So the specific energy generation rate by hydrogen burning in cell k of
the model is

  s% eps_nuc_categories(ipp, k) + s% eps_nuc_categories(icno, k)

Hope that helps,
Josiah
