The formation and future evolution of the first Be black hole binary: MWC 656
Abstract
The first Be binary with a black hole has just recently been discovered. We study its formation and future evolution. The existence of Be binaries with black holes may provide useful constraints on the common-envelope phase and black-hole natal kicks. The future evolution of MWC 656 with a 5 Msun black hole and a 10-16 Msun main-sequence companion, may lead to the formation of a BH-NS binary. Such binaries are not known, but they are expected to be strong gravitational-wave sources for advanced LIGO and Virgo.
