[mesa-users] Vink_wind_eta

[Zsolt Keszthelyi]

It's a little bit unlucky nomenclature though, since in stellar wind physics the eta is the so-called wind efficiency / performance number and has nothing to do with a numerical scaling factor. (It might be useful to change it in the next version.)

Cheers, 
 Zsolt
