我们介绍了大型恒星下自适应光学调查的结果，其中的目标是直接成像新的亚恒星伙伴(11.8)，而在其余22颗没有探测到伴星的恒星中，只有23颗−6+11%有显著的加速。加速度的重要性随着伴星间距的增加而减小。在未来的轨道监测中，这些年轻的、正在加速的低质量恒星及其伴星最终将产生动力质量。
We present results from the Large Adaptive optics Survey for Substellar Objects, where the goal is to directly image new substellar companions (11.8 ), while only 23−6+11 % of the remaining 22 stars with no detected companion have significant accelerations. The significance of the acceleration decreases with increasing companion separation. These young accelerating low-mass stars with companions will eventually yield dynamical masses with future orbit monitoring.
