[mesa-users] Custom Irradiation

[Pablo Marchant]

For the case of a system that is undergoing RLOF, the stellar wind is
considered together with the mass transfer. This means that the star will
be losing mass at the given rate taking away the specific angular momentum
of its orbit, and on top of this MESA will compute a mass transfer rate
according to whatever prescription is being used.

So, using other_wind should work, barring as Bill says violent variations
that could make convergence difficult.

Cheers!
