XMM-Newton's view of a RS CVn binary CF Tuc

Sriram, K.; Agrawal, Vivek K.; Lahiri, Deblina +1 more

Coronal emission exhibited by the chromospherically active binaries is important to understand the underlying mechanism. We report the X-ray spectral studies of an RS CVn source CF Tuc using XMM-Newton archival data. The light curve was found to be steady with no flaring activity and the source was in a quiescent X-ray emission state. The source s…

X-ray reprocessing: Through the eclipse spectra of low mass X-ray binaries with XMM-Newton

Paul, Biswajit; Aftab, Nafisa

Eclipsing X-ray binaries make an ideal condition to study reprocessed X-rays, as the X-rays detected during eclipse are purely reprocessed while the much brighter primary X-rays are blocked by the companion star. We carried out a comprehensive study of X-ray reprocessing with four eclipsing Low Mass X-ray Binary (LMXB) systems by comparing X-ray s…
