Scientific paper

Optical spectroscopic observations of the X-ray nova A0620-00 taken in March 1986 are presented. The radial velocity data confirm the results of McClintock and Remillard (1986) that the minimum mass of the central object, 3.2 solar masses, is above the maximum allowed mass for a neutron star, and hence the compact object must be a black hole. Also presented are new observations of emission lines arising from the accretion disk. These show the characteristic double-peaked profile associated with disk emission, although the peaks are asymmetrical and vary systematically over the orbit.
