A FWHM–<i>K</i><sub>2</sub>CORRELATION IN BLACK HOLE TRANSIENTS
We compare emission profiles of 12 dynamically confirmed black holes (BHs) and 2 neutron star X-ray transients (SXTs) in quiescence with those of a sample of 43 Cataclysmic Variables (CVs), also quiescent. The FWHM of the line in SXTs is tightly correlated with the velocity semi-amplitude of the donor star …
