[Mesa-users] Evolution of helium stars

[Rob Farmer]

Hi,
You can make a pure helium star using:

create_pre_main_sequence_model = .true.

in your star_job inlist

and then setting in your controls inlist (initial_z, inital_y, and
initial_he3) such that:

initial_z + inital_y + initial_he3 = 1

This will make a star without any H (the remainder from 1 - ( initial_z +
inital_y + initial_he3) is what sets the amount of H in a model)
