Trapped, Two-Armed, Nearly Vertical Oscillations in Disks with Toroidal Magnetic Fields
Shoji Kato
We have examined trapping of two-armed () nearly vertical oscillations (vertical p-mode) in vertically isothermal ( const.) relativistic disks with toroidal magnet…
Excitation of Trapped g-Mode Oscillations in Warped Disks around Black Holes
Finny Oktariani, Atsuo T. Okazaki, Shoji Kato
In order to study the origin of high-frequency quasi-periodic oscillations observed in X-ray binaries, Kato (2004) suggested a resonant excitation mechanism of disk oscillations in…
Trapped, Two-Armed, Nearly Vertical Oscillations in Polytropic Disks
Shoji Kato
We have examined trapping of two-armed nearly vertical oscillations in polytropic disks. Two-armed nearly vertical oscillations are interesting in the sense that they are trapped i…
Leaving the ISCO: the inner edge of a black-hole accretion disk at various luminosities
Marek A. Abramowicz, Michal Jaroszynski, Shoji Kato +3
The "radiation inner edge" of an accretion disk is defined as the inner boundary of the region from which most of the luminosity emerges. Similarly, the "reflection edge" is the sm…
