[Mesa-users] Neutrino Interactions

[Liam Kroll]

Hi all,

Josiah, thank you for the clarification.
Sean, that's excellent, I will check it out.
Francis, I did have nucleosynthesis in mind. I was hoping to play around
with the rates of the previously mentioned reactions and see how that
effects the nucleosynthesis in neutrino driven winds. I have made a
core-collapse supernova using the mass cut and energy injection method
based on the test_suite example and instrument papers.

Any ideas on if this is something that is feasible to implement myself or a
fool's errand?

Thanks again for all the input,
Liam
