Disk-Regulated Mass Transfer Between Rotating Non-Degenerate Stars: Insights from Be and sdOB Binaries
Zepei Xing, Tassos Fragos, Vicky Kalogera +3
Mass transfer between non-degenerate stars is a fundamental but still poorly understood process in binary evolution. The commonly used rotationally limited accretion prescription i…
A case for Case A: detailed look at binary black hole formation through stable mass transfer
Max M. Briel, Tassos Fragos, Monica Gallegos-Garcia +8
In isolated binary evolution, binary black hole (BBH) mergers are generally formed through stable mass transfer (SMT) or common envelope evolution. In recent years, the SMT channel…
