摘要:

2013年12月19日,盖亚飞船由联盟号火箭从法属圭亚那成功发射,并开始了其惊人的旅程,用其10亿像素的相机绘制和拍摄10亿天体。在本报告中,我们简要回顾了任务的总体目标,并描述了自发射以来发生的情况,包括南极极扫描模式。我们还特别关注双星,从一些基本的观测方面开始,然后转向盖亚预计将为这些物体带来的显着收获。

英文摘要:

On the 19th of December 2013, the Gaia spacecraft was successfully launched by a Soyuz rocket from French Guiana and started its amazing journey to map and characterise one billion celestial objects with its one billion pixel camera. In this presentation, we briefly review the general aims of the mission and describe what has happened since launch, including the Ecliptic Pole scanning mode. We also focus especially on binary stars, starting with some basic observational aspects, and then turning to the remarkable harvest that Gaia is expected to yield for these objects.
