论文摘要
给出了2019年4.1 m南方天体物理研究望远镜（SOAR）的斑点干涉观察结果，总计2555个测量1972年的分离对分解，分别为15个MAS（中位数为0.21英寸），幅度（中位数）（中位数）（中位数）和最高6个MAG的差异，并在684个目标上进行了较高的工作。继续我们的长期斑点计划。
The results of speckle interferometric observations at the 4.1 m Southern Astrophysical Research Telescope (SOAR) in 2019 are given, totaling 2555 measurements of 1972 resolved pairs with separations from 15 mas (median 0.21") and magnitude difference up to 6 mag, and non-resolutions of 684 targets. We resolved for the first time 90 new pairs or subsystems in known binaries. This work continues our long-term speckle program. Its main goal is to monitor orbital motion of close binaries, including members of high-order hierarchies and Hipparcos pairs in the solar neighborhood. We give a list of 127 orbits computed using our latest measurements. Their quality varies from excellent (25 orbits of grades 1 and 2) to provisional (47 orbits of grades 4 and 5).
