摘要:

我们提出了一个大规模的银河系O型星,GOSSS光谱调查的基础上,新的,高信噪比,R~2500蓝紫数字观测从两个半球。样本量和选择标准; GOSSS,银河系O-星表(GOSC),和三个姐妹调查(OWN,IACOB,和幸运成像)之间的关系;目前的状态;和我们的计划,为未来进行了讨论。我们还展示了我们的一些第一批结果,其中包括新的OFC类别,两个新的例子?p星,一个新的O星图集,并介绍了O9.7型光度类III至V。最后,我们的科学目标进行了讨论。

英文摘要:

We present a massive spectroscopic survey of Galactic O stars, GOSSS, based on new, high signal-to-noise ratio, R~2500 blue-violet digital observations from both hemispheres. The sample size and selection criteria; the relationship between GOSSS, the Galactic O-Star Catalog (GOSC), and three sister surveys (OWN, IACOB, and Lucky Imaging); the current status; and our plans for the future are discussed. We also show some of our first results, which include the new Ofc category, two new examples of Of?p stars, a new atlas for O stars, and the introduction of the O9.7 type for luminosity classes III to V. Finally, our scientific objectives are discussed.
