A C IV emission feature in the near-ultraviolet spectrum of the Wolf-Rayet star gamma 2 Velorum.
Abstract
Spectrophotometric satellite observations in the ultraviolet of the binary y2 Vel are presented. Spectral features are tentatively identified. An explanation for the strength of the dominating C iv A2529.97 emission line is suggested. The diffuse red wing of this line suggests mass transfer from the Wolf-Rayet star to the 0-type component. Subject headings: binaries -- emission-line stars line identification - mass loss - spectra, ultraviolet - stars, individual - Wolf-Rayet stars
