Title: Numerical Studies of sub-Keplerian Accretion Disk onto Black Holes
Speaker: Sudip K. Garain (KASI)
Abstract: Two component advective flow (TCAF) model is quite successful in explaining the spectral and timing properties of the accretion disk around black holes. The sub-Keplerian flow is an important component of TCAF model because it is responsible for producing the observed hard radiation in this model. In this talk, I shall mostly discuss the analytical solutions and numerical experiments of the advective sub-Keplerian disk. I shall also present some simulation results showing how such disk can explain the observed radiations from the black hole binaries.
