Interface Modes and Their Instabilities in Accretion Disc Boundary Layers
David Tsang, Dong Lai
We study global non-axisymmetric oscillation modes trapped near the inner boundary of an accretion disc. Observations indicate that some of the quasi-periodic oscillations (QPOs) o…

Corotational Damping of Diskoseismic C-modes in Black Hole Accretion Discs
David Tsang, Dong Lai
Diskoseismic c-modes in accretion discs have been invoked to explain low-frequency variabilities observed in black-hole X-ray binaries. These modes are trapped in the inner-most re…

Corotational Instability of Inertial-Acoustic Modes in Black Hole Accretion Discs and Quasi-Periodic Oscillations
Dong Lai, David Tsang
We study the global stability of non-axisymmetric p-modes (also called inertial-acoustic modes) trapped in the inner-most regions of accretion discs around black holes. We show tha…
