[mesa-users] RE-preMS atmospheres and T-tau relations

[David Arnett]

Unlike grey and Eddington boundary condidtions which are theoretically sane
if simplistic,
the T-tau relations have an empirical basis, which causes problems if used
for different
physical situations. So bad convergence for pre-MS models should be no
surprise I think;
we are extrapolating some physics assumptions with the T-tau which may be
outside their
valid range.
