盖亚时代的10秒差距样本:首次更新

The 10 parsec sample in the Gaia era: first update

C. Reyle, K. Jardine, P. Fouque, J. A. Caballero, R. L. Smart, A. Sozzetti

摘要:

最近的恒星为我们理解恒星物理和银河系提供了一个基本的限制。附近的样本作为一个锚点,所有对象都可以通过精确的数据进行研究和理解。这项工作是Reylé等人(2021)发表的10 pc样本的更新,该样本使用了来自天体测量太空任务Gaia早期第三次数据发布的前所未有的高精度视差测量。我们回顾这次普查,所有更新都与近距离双星,褐矮星和系外行星有关。我们提供了一个新的541颗恒星,棕矮星和系外行星的目录,这些恒星位于距离太阳10 pc以内的336个系统中。这个列表是尽可能完整的卷从目前的知识,它提供了一个基准星的列表。我们还探索了最近第三次盖亚数据发布中提供的新产品。

英文摘要:

The nearest stars provide a fundamental constraint for our understanding of stellar physics and the Galaxy. The nearby sample serves as an anchor where all objects can be studied and understood with precise data. This work is an update of the 10 pc sample published by Reylé et al. (2021) that used the unprecedented high precision parallax measurements from the early third data release of the astrometric space mission Gaia. We review this census, all updates being related to close binaries, brown dwarfs and exoplanets. We provide a new catalogue of 541 stars, brown dwarfs, and exoplanets in 336 systems within 10 pc from the Sun. This list is as volume-complete as possible from current knowledge and it provides a list of benchmark stars. We also explore the new products made available in the most recent third Gaia data release.
