[Mesa-users] Problem with a Mass loss from a binary

[AbdelBassit Senhadji]

Hi,

I was wondering if we do have in MESA a parameter than can take off the mass from a binary on a constant way.

What I am trying to do is to evolve two stars (5.5 for M1 and 3.79 for M2) with a period of 3 days. At a certain time the donor will fill it's Roche lobe and the period reached 90 days. I am also using mass loss fractions ( alpha and beta).

I tried to stop at this model and use the last model but with a different initial period ( my goal is to let the companion loose it's mass again) both stars are in a common envelope and want to take away that ...

Is it correct what I am doing ( I mean restarting the final model with a new period)? I also tried to relax both masses, used different wind scheme and trigger angular momentum without any success.


Any suggestions or help would be very appreciated!


Thanks
Abdel
