Spectroscopic analysis of Scorpius X-1.
Abstract
Radial velocity and intensity measurements are presented for the strongest emission lines observed during four nights of continuous observation of Sco X- 1. In general, the observations are consistent with a model in which the emission spectrum originates from an accretion disk surrounding the X-ray source. Some of the observations do not fit this simple model, but lack of phase overlap in the observations precludes further interpretation. A value of i 300 and probable masses of Mx 1.3 M0 and M2 1 M0 are inferred from the observations. Subject headings: stars: binaries - stars: individual - X-rays: sources
