Spin 3/5 Black Hole in GRO J1655-40?
Andrei Gruzinov
When a bright spot in a high-inclination disk orbits a black hole, its light is periodically lensed and Doppler shifted. If the spots occupy a narrow range of radii, a quasi-period…
Comment on "Dynamic Screening..." by Opher and Opher
Andrei Gruzinov
I have shown that the enhancement of fusion rates in stars due to electrostatic screening does not depend on the Gamow energy of the fusing nuclei (in the classical weak screening…
Flares on the Black Holes
Andrei Gruzinov
A Kerr black hole can flare quasi-periodically, if it is magnetically connected to the accretion disk. The flares extract the rotational energy of the hole. The flaring occurs beca…
Collisionless Halos Around Black Holes
Andrei Gruzinov
When a black hole accretes slowly, the radiative cooling of the infalling gas is weak and the accretion disk does not form. A hot collisionless quasi-spherical halo is formed inste…
Stability in Force-Free Electrodynamics
Andrei Gruzinov
We show that flows of pure electromagnetic energy are subject to instabilities familiar from hydrodynamics and plasma physics---Kelvin-Helmholtz and screw instabilities. In the fra…
