Initial detection of binary candidates among WN stars
Spectroscopic data collected for approximately 50 stars
First results from the 2007-2008 campaign
Abstract
We are carrying out a spectroscopic monitoring of Galactic Wolf-Rayet stars, in order to detect binary systems. The sample consists of approximately 50 stars of the Nitrogen sequence (WN) and fainter than V = 13. The observations are made from the 4-m telescope at CTIO, Chile. In the following, we present the first results of the 2007-2008 campaign.
