[Mesa-users] How to make a model a neutron star together with thick atomsphere ?

[Rob Farmer]

Hi,

The 10km radius specific in the neutron_star_envelope test case only
relates to the size of the inner boundary of the neutron star. You can
accrete material using the same mass change controls as for a normal star (
http://mesa.sourceforge.net/controls_defaults.html#mass_gain_or_loss) or
take the final saved model from neutron_star_envelope and load that into a
binary system and do accretion from a companion.
