Time-resolved Spectroscopy of V Sagittae
Abstract
An observational study of the peculiar binary V Sagittae is presented with the aim of constraining the stellar masses and current models for the mass transfer in this system. The radial velocity curves of the Hβ and He II lambda4686 emission lines at low photometric state are derived. Possible physical scenarios for the line-forming region are discussed on the basis of the line profile orbital behavior. In addition, an exploratory analysis of the X-ray data on V Sge is made with the aim of addressing quantitatively the proposed models for this binary.
