Simultaneous observations of variable stars. III. The WR-star gamma 2 Velorum.
Abstract
Summary. Simultaneous measurements with two instruments of the WR binary y2 Vel could not confirm the existence of intrinsic short time periodic or quasiperiodic variations in the observed emission lines and continuum regions. Night to night variations in emission lines as well as in polarization were present. The low degree of polarization indicates a quite symmetric shell. Key words: variable stars WR-stars - photometry - polarimetry
