Multiwavelength observations of EXO 0748-676. II. Emission-line behavior

Abstract:

We present optical and ultraviolet spectra, light curves, and Doppler tomograms of the low-mass X-ray binary EXO 0748-676. Using an extensive set of 15 emission-line tomograms, we show that, along with the usual emission from the stream and "hot spot," there is extended nonaxisymmetric emission from the disk rim. Some of the emission and Ha and Hβ absorption features lend weight to the hypothesis that part of the stream overflows the disk rim and forms a two phase medium. The data are consist...
