[Mesa-users] Case B mass transfer at solar metallicity

[Debasish Dutta]

Hi,
I am trying to evolve a binary system with a black hole companion. I am
interested in getting a Case B mass transfer. For lower metallicity models
(SMC, LMC and Zsun/10), it seems to work well. However, for higher
metallicity (~solar) massive models, I could not get the Case B mass
transfer. I was using the initial orbital periods as 70 days for the lower
metallicity models. In the case of solar metallicity, if I use an extended
period (~450 days), I get some weird HR diagrams with the mass transfer
phase almost non-existent. I  have attached my inlists and also a HR
diagram of a 42 solar mass model at solar metallicity (mass ratio=0.6).

I would be glad if someone could help me regarding this.

Regards
Debasish
