RXTE observes a transition to the low-hard state in H1743-322
Abstract
The galactic black hole candidate H1743-322 has been in the high soft state since the rise state transition in late August 2010 (Atel #2797). Recent observations of H 1743-322 with RXTE/PCA showed the spectral and variability evolution consistent with the source being in a decay transition from the high soft state back to the low hard state. Beginning on September 16, 2010 10:02 UT the source lightcurve showed quasi-periodic oscillations (QPOs) slowing down from 7 Hz during that observation to 1 Hz during the latest observation on September 21, 2010 13:56 UT.
