[Mesa-users] lithium abundance in convective core

[Bill Paxton]

Ahhh!   Are you saying that you agree with the result but are curious about the numerics?  

I misunderstood you to be asking about how mesa was showing variation in Li abundance inside a convective region.

Thanks to Aldo for correctly interpreting (guessing?) your question.  ;-)

Cheers,
Bill

I was just wondering whether the treatment of the short timescales involved in lithium burning and convective mixing needed special numerical schemes, but Aldo Serenelli just pointed out that using implicit time integration is sufficient to handle this issue correctly. Thanks Aldo for the answer! And sorry to have disturbed you.
