Microflares in accretion disks
V. Krishan, S. Ramadurai, P. J. Wiita
We have investigated the phenomenon of explosive chromospheric evaporation from an accretion disk as a mechanism for fast variability in accreting sources such as low mass X-ray bi…

Effect of Beam-Plasma Instabilities on Accretion Disk Flares
Vinod Krishan, Paul J. Wiita, S. Ramadurai
We show that a certain class of flare models for variability from accretion disk coronae are subject to beam-plasma instabilities. These instabilities can prevent significant direc…
