[Mesa-users] Nonphysical behavior of outermost envelope of rapidly rotating stars

[Larry Molnar]

Here are some sample log(rho)-log(T) plots for the case of M = 1.0 Msun, Omega/Omega_crit (initial) = 0.42. The excursion to low surface temperature/large radius occurred in profiles 146-225. My samples include before, during and after the excursion.

I see that the density briefly *increases* with increasing radius in the outermost layers of the suspect profiles.

Larry -

Can you show the log(rho)-log(T) plot, please? How the density looks like in the surface layers?
