[Mesa-users] Turning off angular momentum transfer in MESA

Hello all,

I've been trying to find settings in control.defaults and star_job.defaults to turn off MESA's angular momentum transfer during mass transfer. MESA's prebuilt angular momentum transfer spins up the gainer star in a binary star system to the break up speed too quickly. The spin down equations I'm using are no where near the same order of magnitude as MESA's spin up effects. MESA does a wonderful job reproducing the order of magnitudes I need to reproduce data of a paper for spin of the gainer.

Thank you kindly,
