标题： The IACOB project: synergies for the Gaia era

摘要： IACOB银河系OB星光谱调查是一项具有雄心的观测项目，旨在编制一个大型、均匀、高分辨率的光学光谱数据库，该数据库包含从北半球可观测的大质量恒星。 对该数据库的定量光谱分析，结合盖亚（Gaia）提供的宝贵信息（主要是关于光度和距离的信息），将是我们了解银河系大质量恒星基本物理特征的重要进展。 此外，此分析的结果还将对其他利用盖亚观测进行研究的科学问题具有重要意义。 在本次贡献中，我们概述了IACOB光谱数据库的当前状态，并简要指出了IACOB和盖亚科学项目之间的协同联系。 显示英文摘要

摘要： The IACOB spectroscopic survey of Galactic OB stars is an ambitious observational project aimed at compiling a large, homogeneous, high-resolution database of optical spectra of massive stars observable from the Northern hemisphere. The quantitative spectroscopic analysis of this database, complemented by the invaluable information provided by Gaia (mainly regarding photometry and distances), will represent a major step forward in our knowledge of the fundamental physical characteristics of Galactic massive stars. In addition, results from this analysis will be of interest for other scientific questions to be investigated using Gaia observations. In this contribution we outline the present status of the IACOB spectroscopic database and indicate briefly some of the synergy links between the IACOB and Gaia scientific projects.
