盖亚时代的天文距离尺度

Astronomical distance scales in the Gaia era

F. Mignard

摘要:

从天文学的观点看天文距离的测定。考虑了从太阳系(行星距离)到河外距离的距离,特别强调三角恒星距离的基本步骤和最近由于欧空局的依巴谷和盖亚空间天体测量飞行任务而在这一领域经历的巨大飞跃。

英文摘要:

Overview of the determination of astronomical distances from a metrological standpoint. Distances are considered from the Solar System (planetary distances) to extragalactic distances, with a special emphasis on the fundamental step of the trigonometric stellar distances and the giant leap recently experienced in this field thanks to the ESA space astrometry missions Hipparcos and Gaia.
