EXOSAT X-ray Light Curves of SS ARI
Abstract
We construct the X-ray light curves of the W UMa type contact binary SS Arietis (HD12929) from the EXOSAT data in HEASARC data archive. The phase dependent X-ray light curves obtained by using the ephemeris of Kaluzny & Pojmanski (1984) have been presented. The resulting X-ray light curves show that the X-ray radiation of SS Ari is modulated on the orbital phase as in the case of other W UMa type binaries. Although a detailed analysis of these data is impossible because of the very low count rate of this star in the X-ray region, we try to find the physical explanation of the X-ray light curves in the context of the radiation in the corona region of W UMa type stars.
