We report on the pointed X-ray analysis of Magnetic Cataclysmic Variable (mCV) Ex Hya data from the High Energy and Astrophysical Science Archive Research Centre (HEASARC). The observation was made by the Suzaku team using the Suzaku satellite. Ex Hya was observed with Suzaku satellite on 18-07-2007 for 91 kiloseconds (ks). We modeled the spectrum of the system with a Thermal bremsstrahlung model plus three Gaussian lines for the iron lines. We resolved the neutral or low-ionized (6.41 keV), He-like (6.70 keV), and H-like (7.00 keV) lines. The absorbing hydrogen column density in both the full...
We report on the pointed X-ray analysis of Magnetic Cataclysmic Variable (mCV) Ex Hya data from the High Energy and Astrophysical Science Archive Research Centre (HEASARC).

We modeled the spectrum of the system with a Thermal bremsstrahlung model plus three Gaussian lines for the iron lines. We resolved the neutral or low-ionized (6.41 keV), He-like (6.70 keV), and H-like (7.00 keV) lines. The absorbing hydrogen column density in both the full and partial covering is not seen in our source. The Fe Ka fluorescence line in Ex Hya is created due to irradiation of the accretion disk by hard X-ray from the shock region, while the 6.70 and 7.00 are as a result of collisional ionization of the k-shell followed by florescence of atoms in ionized state due to reflection on the hot white dwarf surface.
