Magnetic braking of Ap/Bp stars: application to compact black-hole X-ray binaries
Magnetic braking of Ap/Bp stars: application to compact black-hole X-ray binaries
We examine the proposal that the subset of neutron-star and black-hole X-ray binaries that form with Ap or Bp star companions will experience systemic angular-momentum losses due to magnetic braking, not otherwise operative with intermediate-mass companion stars. We suggest that for donor stars possessing the anomalously high magnetic fields associated …
