[mesa-users] Extending MESA for mass-loss

[Bill Paxton]

Hi, 

The arguments to other_wind include the current mass (in grams) along with L, R, and T.   

I suggest using s% time for age in seconds (the s% star_age variable is not updated until after the call on other_wind).

Good luck,

Bill

One of my problems is that I don't know what variable in star_def to use for time and Solar mass at that given time. Do you think this is the best approach toward implementing mass loss in this form for a 1-1.15M solar evolution model of the sun, or is there a better approach?
