Abstract Type : Poster Abstract Category : Stars,ISM and the Galaxy Abstract : Cyg X-3 is a X-ray binary with a compact object possibly a black hole and Wolf-Rayet star as a companion. We have performed high resolution spectroscopy of Cyg X-3 using five Chandra HETG observations in 1.82–7.5 keV energy range. Cyg X-3 reveals several emission features such as hydrogen-like and Helium-like lines of Fe, S, Si, Mg and Ar. We have also performed spectral analysis using NuSTAR observation of 2015 and 2016. In our analysis, Si XIII, Mg XII, Si XIV, S XV , S XVI, Ar XVII, Ar XVIII, Ca XIX, Fe K and Fe XXV lines are apparent in all spectra. Width of the Si XIV and S XVI lines, indicate electron temperature of plasma, KTe ~ 6 eV. We studied variation of different lines over the orbital phase. |
