Our Galaxy hosts a very massive object at its centre, often referred to as the supermassive black hole Sgr A*. Its gravitational tidal field is so intense that can strip apart a binary star passing its vicinity and accelerate one of the components of the binary as hypervelocity star (HVS) and grab the other star as S-star. Taken into consideration that many binary star systems are known to host planets, in this paper we aim to broaden the study of the close interaction of binary stars and their planetary systems with Sgr A* massive object. Results are obtained via a high precision $N-$body code including post-Newtonian approximation. We quantify the likelihood of capture and ejection of stars and planets after interaction with Sgr A*, finding that the fraction of stars captured around it is about three times that of the planets (~ 49.4% versus ~14.5%) and the fraction of hypervelocity planet (HVP) ejection is about twice HVSs (~21.7% versus ~9.0%). The actual possibility of observational counterparts deserves further investigation.

双星与人马座 A* 黑洞相互作用时承载行星的命运

我们的银河系中心有一个非常大的物体，通常被称为超大质量黑洞 Sgr A*。它的引力潮汐场非常强烈，可以将经过它附近的双星剥离，并将双星的一个组成部分加速为超高速星 (HVS)，并以 S 星的形式抓住另一颗恒星。考虑到已知许多双星系统拥有行星，在本文中，我们旨在拓宽双星及其行星系统与 Sgr A* 大质量物体的密切相互作用的研究。结果是通过高精度 $N-$body 代码获得的，包括后牛顿近似。我们量化了与人马座 A* 相互作用后捕获和抛射恒星和行星的可能性，发现在它周围捕获的恒星比例约为行星的三倍（~49.4% 对~14.0%）。5%)，而超高速行星 (HVP) 喷射的比例大约是 HVS 的两倍（~21.7% 对~9.0%）。观测对应物的实际可能性值得进一步研究。
