[Mesa-users] Suppressing CNO reactions

[RICHARD H D TOWNSEND]

Hi folks --

A question that I'm sure I've asked before, but I can't seem to find it in the archives: what's a straightforward approach to suppressing CNO reactions in a MESA run? I'd like to do this to demonstrate to my class what would happen to the luminosity of massive ZAMS stars if they were 'forced' to use the PP chain.

cheers,

Rich
