Spectral states and state preference of galactic X-ray binaries
Abstract
Using observations in the past four years with the All Sky Monitor (ASM) onboard the Rossi X-ray Timing Explorer (RXTE) and the Burst Alert Telescope (BAT) onboard the Swift, we demonstrate that the hard state and the soft state are the primary spectral states in galactic black hole and neutron star X-ray binaries. In addition, we show quantitatively the preference of the two spectral states for each of the 22 bright persistent sources.
