论文摘要
HIP 53731是由光谱类型K0和K9的恒星组成的二进制。该物体的轨道先前由Cvetkovi'c等人构建。 （2016年），由Tokovinin（2019）改进。应该注意的是，某些已发表的测量值的位置角度存在180度歧义。本文作者的作者在2007 - 2020年（21个测量值）的SAO RAS（BTA）望远镜上获得了斑点干涉测量值。对新数据的分析以及先前发布的数据的分析使得构建髋关节53731的准确轨道并将系统轨道周期的已知值减半。研究的结果是，通过两种独立方法确定了质量总和，每个组件及其光谱类型的质量。根据轨道的定性分类，轨道溶液具有2级 - “良好”（观测值覆盖了轨道时期的一半以上，对应于不同的阶段）。
HIP 53731 is a binary consisting of stars of the spectral types K0 and K9. Orbit of this object was constructed previously by Cvetkovi'c et al. (2016) and improved by Tokovinin (2019). It should be noted that there is an 180 degree ambiguity in the position angles of some published measurements. Speckle interferometric observations were obtained in 2007-2020 (21 measurements) at the 6-m telescope of the SAO RAS (BTA) by the authors of this article. The analysis of new data together with previously published ones made it possible to construct the accurate orbit of HIP 53731 and to halve the already known values of the orbital period of the system. As a result of the study, the mass sum, the masses of each component and their spectral types were determined by two independent methods. According to the qualitative classification of orbits, the orbital solution has grade 2 - "good" (observations cover more than half of the orbital period and correspond to different phases).
