The Role of Complex Ionized Absorbers in the Soft X-Ray Spectra of Intermediate Polars

چکیده

In magnetic cataclysmic variables (mCVs), X-ray radiation originates from a shock-heated, multi-temperature plasma in the post-shock region near white dwarf's surface. These X-rays are modified by complex distribution of absorbers pre-shock region. The presence photoionized lines and warm absorber features soft spectra these mCVs suggests that ionized. We developed ionized model zxipab, which is represented power-law flow. Using zxipab along with cooling flow reflection component, we broadband Chandra/High-Energy Transmission Grating (HETG) Nuclear Spectroscopic Telescope Array (NuSTAR) two intermediate polars (IPs): NY Lup V1223 Sgr. find this describes well many H- He-like emission medium-Z elements, arise collisionally excited plasma.

BeppoSAX observations of soft X-ray Intermediate Polars

We present broad-band (0.1–90 keV) spectral and temporal properties of the three Intermediate Polars, RE0751+144 (PQGem), RXJ0558.0+5353 (V405Aur) and RXJ1712.6−2414 (V2400Oph) based on simultaneous soft and hard X-ray observations with the BeppoSAX satellite. The analysis of their spectra over the wide energy range of BeppoSAX instruments allows us to identify the soft and hard X-ray component...
