Re: [mesa-users] Fwd: Wind loss in MESA

[Jiri K. <kr...@mo...>]

Hi,

Just a comment: Please note that de Jager et al. 1988A&AS...72..259D wind 
mass-loss rates are based on observations of stars with log L>3, 
consequently using them for low-mass MS stars is a huge extrapolation.

Cheers,

Jiri

In my simulations I want the donor star to begin with a certain rotational velocity, synchronize with the orbit and emit wind (enhanced by tidal effects). I see that in this version of MESA all this is possible and so I want to take advantage of this.
