Subject: X-RAY BINARIES

BINARY FORMATION AND POST COLLAPSED CLUSTERS


ABSTRACT

Though ASCA observations of AO1 to AO4, we found many dim X-ray sources in globular clusters, and found evidence of the existance of CVs from their energy spectra obtained for the first time. Clusters previously observed are dense and/or large. This time, we propose observations of low dense but collapsed clusters. The "collapsed" means that the clusters were much highly dense before. The existance X-ray binaries in such clusters tell us the influence of the collapse of the clusters on the binary formation.
