[Mesa-users] Detect zones with H fusion

[Roque Caballero Navarro]

Hi Josiah,

Many thanks for the explanation.

Is it possible to go even finer and to distinguish the contribution of the different p-p reaction branches?

Kind regards,

Roque

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?

You probably want to test against a finite value, since something like 10^{-100} erg/g/s is "no hydrogen burning" for all intents and purposes.

For example, MESA sometimes uses 1 erg/g/s for this value.  That's arbitrary, but since things are usually exponentially sensitive to temperature, the exact value is unimportant.

Hope that helps,
Josiah
