摘要:

我们正在对银河系沃尔夫-拉叶星进行光谱监测,以探测双星系统。该样本由大约50颗N星序列(WN)的恒星组成,比V = 13更暗。这些观测是由智利CTIO的4米望远镜进行的。在下文中,我们介绍了2007-2008年运动的初步成果。

英文摘要:

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.
