Black hole transient during transition from hard to soft state
Abstract
We propose a ToO observation of a transient black-hole candidate, either known or unknown, during its transition from hard to soft state. This transition, which takes place at high flux levels, encompasses marked changes in the properties of the accretion flow and it includes the time at which the ejection of an accelerating relativistic jet stops abruptly. The study of the soft spectral component as well as the behaviour of the iron line is important for our understanding of the accretion disc during state transition. We would like to investigate in particular the process responsible for the disappearance of the variability in the soft energy band, which has been detected in the hard state with XMM-Newton, but is absent in the soft state.
