论文摘要
我们的星系在其中心设有一个非常庞大的物体，通常称为超大质量黑洞SGR A*。它的引力潮汐场是如此强烈，可以剥离二进制恒星通过其附近，并加速二进制组件之一，将二进制恒星（HVS）作为Shyplecity Star（HVS），并抓住另一个恒星作为S-Star。考虑到许多二进制恒星系统众所周知可以容纳行星，在本文中，我们旨在扩大对二元恒星及其行星系统与SGR A*大量物体的紧密相互作用的研究。结果是通过高精度$ n- $的主体代码获得的，包括牛顿后近似。我们量化了与SGR A*相互作用后捕获和射击星星和行星的可能性，发现周围捕获的星星的比例大约是行星的三倍（约49.4％对〜14.5％），而超速行星（HVP）弹丸（HVP）弹药的一部分大约是HVSS（〜21.7％Versus 〜9.9.9.9.9.0.0％）。观察性对应物的实际可能性值得进一步研究。
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.
