Complex Absorption and Reflection of a Multi-temperature Cyclotron-Bremsstrahlung X-ray Cooling Shock in BY Cam
C. Done, P. Magdziarz
We re-analyse the ASCA and GINGA X-ray data from BY Cam, a slightly asynchronous magnetic accreting white dwarf. The spectra are strongly affected by complex absorption, which we m…
Relativistic smearing of the reflection spectrum in Galactic Black Hole Candidates
C. Done, P. T. Zycki, D. A. Smith
We identify the reflected component in the GINGA spectra of Nova Muscae, a Black Hole transient system which has been used as the prototype for the recent advection dominated disk…
The X-ray spectrum of the polar BY Cam
C. Done, P. Magdziarz
ASCA and GINGA X-ray data from the magnetic Cataclysmic Variable BY Cam show that the spectrum is strongly affected by complex absorption, probably from the pre-shock accretion col…
Geometry of accretion in Soft X-ray Transients
P. T. Zycki, C. Done, D. A. Smith
We present results of modelling Ginga data of a number of Soft X-ray Transient sources performed with the aim of constraining the geometry of accretion during various stages of the…
Relativistically smeared X-ray reprocessed components in the GINGA spectra of GS 2023+338
Piotr Zycki, Chris Done, David Smith
We present results of spectral analysis of Ginga data obtained during the decline phase after the 1989 outburst of GS 2023+338 (V404 Cyg). Our analysis includes detailed modelling…
The X-ray Spectrum of the Dwarf Nova SS Cyg in quiescence and outburst
C. Done, J. P. Osborne
We reanalyse archival GINGA and ASCA X-ray data from SS Cyg in both quiescence and outburst, using multi-temperature plasma models for the continuum and line emission, together wit…
