FUSION - NUCLEAR LUMINOSITY MEASURES,
nucmixflag = 1
gamma = 4/3, n=3, Sirius_A
In units of L_star Sirius_A. This was done with Aller 1961 C&N x 1.75.
This means if we use 1.75 times as much carbon and nitrogen in Sirius A as Aller finds in the Sun, we get the right nuclear luminosity for the star Sirius, using screened carbon cycle fusion from Hubert Reeves and the screened p-p fusion chain from Donald D. Clayton. Helium burning is negligible in Sirius A.
