论文摘要
我们在此报告基于文献中的数据，在hyades群集中，相对于太阳成员，相对于太阳成员，低速（约21〜km $ \ cdot $ 〜S $^{ - 1} $）。结果表明，恒星是羟基的非本地成员恒星，其径向速度小于夏季簇的径向速度，甚至超过了簇的径向速度的标准偏差9。此外，通过分析和比较了这颗星星和宿主的Orbits，它可能会涉及到以前的2个〜，从而使其成为了2岁的主机。如果恒星的当前运动轨道保持不变，则可能会将其主机留在接下来的2〜MYR中。这意味着入侵者之星可能暂时居住在集群中。这项研究提出了恒星侵入簇的第一个观察证据，这表明可以找到更多证据。
We hereby report a low-speed (about~21~km$\cdot$~s$^{-1}$ with respect to the Sun) intruder member in the Hyades cluster based on the data in the literature. The results show that the star is a non-native member star for the Hyades, with its radial velocity being smaller than the radial velocity of the Hyades cluster, even exceeding the standard deviation of the radial velocity of the cluster by a factor of 9. Furthermore, by analyzing and comparing the orbits of this star and its host, it may have intruded into its host in the past 2~Myr. If the star's current motion orbit remains unchanged, it may leave its host in the next 2~Myr. This implies that the intruder star may be temporarily residing in the cluster. This study presents the first observational evidence of a star intrusion into a cluster, which suggests that more evidence may be found.
