Abstract

The GRAVITY instrument was primarily conceived for imaging and astrometry of the Galactic centre. However, its sensitivity and astrometric capabilities have also enabled interferometry to reach a new domain of astrophysics: exoplanetology. In March 2019, the GRAVITY collaboration published the first spectrum and astrometry of an exoplanet obtained by optical interferometry. In this article, we show how this observation is paving the way to even more exciting discoveries — finding new planets, and characterising their atmospheres.

用单模光学干涉测量法寻找系外行星

重力仪器最初是为银河系中心的成像和天体测量而设计的。然而，它的灵敏度和天文测量能力也使干涉测量学进入了天体物理学的一个新领域:系外行星学。2019年3月，GRAVITY合作发表了首个通过光学干涉测量获得的系外行星光谱和天体测量数据。在这篇文章中，我们将展示这一观测是如何为更令人兴奋的发现铺平道路的——发现新的行星，并描述它们的大气层。
