High Energy X-ray Emission from Recurrent Novae in Quiescence: T CrB
Abstract
We present Suzaku X-ray observations of the recurrent nova T CrB in quiescence. T CrB is the first recurrent nova to be detected in the hard-X-ray band (E ∼ 40.0 keV) during quiescence. The X-ray spectrum is consistent with cooling-flow emission emanating from an optically thin region in the boundary layer of an accretion disc around the white dwarf.
The detection of strong stochastic flux variations in the light curve further supports the interpretation of the hard X-ray emission as emanating from a boundary layer.- Publication:
