Screw instability of the magnetic field connecting a rotating black hole with its surrounding disk
D. X. Wang, R. Y. Ma, W. H. Lei +1
Screw instability of the magnetic field connecting a rotating black hole (BH) with its surrounding disk is discussed based on the model of the coexistence of the Blandford-Znajek (…

Magnetic coupling of a rotating black hole with its surrounding accretion disk
D. X. Wang, R. Y. Ma, W. H. Lei +1
Effects of magnetic coupling (MC) of a rotating black hole (BH) with its surrounding accretion disk are discussed in detail in the following aspects: (i) The mapping relation betwe…

An analytic model of rotating hot spot and kHz QPOs in X-ray binaries
D. X. Wang, R. Y. Ma, W. H. Lei +1
An analytic model of rotating hot spot is proposed to explain kilohertz quasi-periodic oscillations (kHz QPO) in X-ray binaries, which is based on the magnetic coupling (MC) of a r…
