Evolution of different Spectral States in Black Hole Binaries with TCAF

Abstract

Observational evidences show that during the outburst, black hole binaries move to different spectral states depending on accretion flow that feeds these objects. However proper physical picture is still unclear, what causes these states change and how the quasi periodic frequency (QPO) in observed lightcurve is related with the disk properties? In a Two Component Advective Flow (TCAF) solution it is established that low angular momentum and low viscous sub-Keplerian flow produces hot corona, which up-scatters soft photons from the Keplerian disk. We analyze several outbursts data of different black hole binaries from different satellites with TCAF and explain the outburst features.
