Magnetic Hair and Reconnection in Black Hole Magnetospheres
Ashley Bransgrove, Bart Ripperda, Alexander Philippov
The no-hair theorem of general relativity states that isolated black holes are characterized by three parameters: mass, spin, and charge. In this Letter we consider Kerr black hole…
Alfvén wave mode conversion in pulsar magnetospheres
Yajie Yuan, Yuri Levin, Ashley Bransgrove +1
The radio emission anomaly coincident with the 2016 glitch of the Vela pulsar may be caused by a star quake that launches Alfvén waves into the magnetosphere, disturbing the origin…
Precessing flaring magnetar as a source of repeating FRB 180916.J0158+65
Yuri Levin, Andrei M. Beloborodov, Ashley Bransgrove
Recently, CHIME detected periodicity in the bursting rate of the repeating FRB 180916.J0158+65. In a popular class of models, the fast radio bursts (FRBs) are created by giant magn…
A Quake Quenching the Vela Pulsar
Ashley Bransgrove, Andrei M. Beloborodov, Yuri Levin
The remarkable null pulse coincident with the 2016 glitch in Vela rotation indicates a dynamical event involving the crust and the magnetosphere of the neutron star. We propose tha…
Magnetic Field Evolution of Neutron Stars I: Basic formalism, numerical techniques, and first results
Ashley Bransgrove, Yuri Levin, Andrei Beloborodov
In this work we explore the evolution of magnetic fields inside strongly magnetized neutron stars in axisymmetry. We model numerically the coupled field evolution in the core and t…
