Formation of Black Hole X-Ray Binaries with Non-degenerate Donors in Globular Clusters

Showed that there is a range where mass transfer from massive giants onto a black hole is stable. This significantly reduced the simulated BH-BH binary formation rate to fall in line with LIGO observations.

Stability of mass transfer from massive giants: double black hole binary formation and ultraluminous X-ray sources

Presented an alternative method in producing black hole X-ray binaries where a black hole captures a subgiant donor and strips a significant amount of mass off the donor.
