Pre-submission Thesis Presentation

Cataclysmic Variables (CV) are accreting binary systems where the material is accreted by the white dwarf (WD) from a Roche-lobe filling late-type main sequence star. The accretion onto the WD is an energetic process producing X-rays ranging from tens of eV to tens of keV and influenced by factors like WD magnetic field, mass accretion rate, binary geometry, etc. In this talk, I shall discuss the X-ray temporal and spectral properties of different classes of interesting CV sources using observations from X-ray satellite observatories like XMM-Newton, NuSTAR, and Swift. We shall talk about a few exceptional sources, called asynchronous polars (AP), like CD Ind, V1432 Aql, and BY Cam, having slightly asynchronous (~<2%) orbital and spin periods of the WD, compared to the perfectly synchronous regular polars. The results will highlight the essential properties like the nature of the multitemperature nature of the plasma, intrinsic absorber, shock height, and periodic modulations in these sources. Next, I shall present the X-ray properties of the unique Intermediate Polar (IP) source, Paloma. This study will explain the physical and geometrical properties of the system and reveal the distinguishing periodic flux modulation feature of this source, which is not commonplace in regular IPs. Lastly, I shall examine the bright and typical Dwarf Nova (DN) source SS Cyg in both its quiescence and outburst phase using broadband X-ray data. The comparison will provide unique insight into how the X-ray emission mechanism, the properties of the boundary layer, and the accretion disk change during both phases of this source.
