摘要:

欧空局盖亚任务将为标准蜡烛领域带来一个新时代。由于前所未有的天体测量精度、全天空覆盖以及光度、分光光度和光谱测量的结合,这一领域将取得进展。该飞行任务的基本成果将是由盖亚数据分析和处理联合会(DPAC)编制的盖亚目录,其中将包含一个可变源分类和特定可变类型恒星的特定特性。我们回顾了造父变星、天琴座RR、长周期变星和食双星将产生什么。

英文摘要:

The ESA Gaia mission will bring a new era to the domain of standard candles. Progresses in this domain will be achieved thanks to unprecedented astrometric precision, whole-sky coverage and the combination of photometric, spectrophotometric and spectroscopic measurements. The fundamental outcome of the mission will be the Gaia catalogue produced by the Gaia Data Analysis and Processing Consortium (DPAC), which will contain a variable source classification and specific properties for stars of specific variability types. We review what will be produced for Cepheids, RR Lyrae, Long Period Variable stars and eclipsing binaries.
