用盖亚映射Milky Way的恒星星族

Mapping the stellar populations of the Milky Way with Gaia

Carla Cacciari

摘要:

盖亚将是欧空局里程碑式的天体测量任务,定于2013年底发射。盖亚将反复绘制整个天空,测量大约10亿个V=20-22等的源。其数据产品将是μas精度的天体测量,光学分光光度计和中等分辨率光谱学。介绍了盖亚空间飞行任务及其特点和性能。对银河系的恒星星族研究的预期影响进行了讨论,特别注意的来源的兴趣CoRoT和开普勒。

英文摘要:

Gaia will be ESA's milestone astrometric mission, and is due for launch at the end of 2013. Gaia will repeatedly map the whole sky measuring about one billion sources to V=20-22 mag. Its data products will be μas accuracy astrometry, optical spectrophotometry and medium resolution spectroscopy. A description of the Gaia space mission and its characteristics and performance is given. The expected impact on Galactic stellar population studies is discussed, with particular attention to the sources of interest for CoRoT and Kepler.
