Multiplicity Study of Exoplanet Host Stars

在我们利用ASTRALUX对系外行星宿主恒星进行多重性研究的过程中，我们已经可以澄清71个行星系统的恒星多重性状况。此外，我们还可以探测到一个新的同向运动的恒星伴星，其伴星关系已通过第二历元的跟踪成像得到证实。现在，我们希望获得一个新的、最近刚刚发现的伴星候选者的第二个历元后续图像，以及30个新的系外行星宿主恒星的第一个历元图像，这些恒星的多样性迄今尚未研究。与ASTRALUX，我们可以检测新的密切恒星系统与系外行星，最具挑战性的环境行星形成，提出的理论。我们的观测将有助于确定恒星多样性对行星形成和演化的真实的影响。

In the course of our multiplicity study of exoplanet host stars with ASTRALUX, we could already clarify the stellar multiplicity status of 71 planetary systems. Furthermore, we could detect one new co-moving stellar companion, whose companionship was proven with 2nd epoch follow-up imaging. Now we want to obtain 2nd epoch follow-up imaging of one new, just recently detected, companion-candidate, as well as 1st epoch images of 30 new exoplanet host stars, whose multiplicity was not studied so far. With ASTRALUX we can detect new close stellar systems with exoplanets, the most challenging environments for planet formation, as proposed by theory. Our observations will contribute to the determination of the real impact of stellar multiplicity on planet formation and evolution.
