Abstract

More than 4000 exoplanets are known to date in systems that differ greatly from our Solar System. In particular, inner exoplanets tend to follow orbits around their parent star that are much more compact than that of Earth. These systems are also extremely diverse, covering a range of intrinsic properties. Studying the main physical processes at play in the innermost regions of the protoplanetary discs is crucial to understanding how these planets form and migrate so close to their host. With GRAVITY, we focused on the study of near-infrared emission of a sample of young intermediatemass stars, the Herbig Ae/Be stars.

在地球轨道上探测赫比格Ae/Be星盘

迄今为止，已知的系外行星有4000多颗，它们与我们的太阳系有很大的不同。特别是，内系外行星倾向于沿着比地球紧凑得多的母恒星轨道运行。这些系统也非常多样化，涵盖了一系列内在属性。研究原行星盘最内层区域的主要物理过程对于理解这些行星是如何形成并迁移到离宿主如此之近的地方至关重要。通过GRAVITY，我们专注于研究年轻的中等质量恒星样本的近红外发射，赫比格Ae/Be恒星。
