Abstract

The results of seventeen years of speckle interferometric monitoring of seven objects (Chara 122Aa, GJ 3010, HIP 1987, GJ 3076, HIP 11253, HIP 11352, and HIP 14929) are presented. Observational data were obtained at the 6 m Big Telescope Alt-azimuthal Special Astrophysical Observatory of the Russian Academy of Science (BTA SAO RAS) from 2007 to the present. Analysis of previously published and new measurements made it possible to construct completely new orbits for Chara 122Aa, HIP 11253, and HIP 14929. The orbit of GJ 3076 cannot be constructed accurately due to the large influence of the weights assigned to the measurements. The resulting orbital solutions are classified based on a grading scheme suggested by W.I. Hartkopf, B.D. Mason and C.E. Worley; most orbits are “definitive” (Grade 1). The mass sums and masses of components calculated by two independent methods using Hipparcos and Gaia DR2 and DR3 parallaxes were compared for the objects under study.

双星系统的长期斑点干涉测量监测：2007-2023 年七个天体的位置测量和轨道研究

本文介绍了对七个天体（Chara 122Aa、GJ 3010、HIP 1987、GJ 3076、HIP 11253、HIP 11352 和 HIP 14929）进行十七年斑点干涉测量监测的结果。观测数据是 2007 年至今在俄罗斯科学院 6 米大望远镜 Alt-azimuthal 特殊天体物理观测台（BTA SAO RAS）获得的。通过分析以前公布的数据和新的测量结果，可以为 Chara 122Aa、HIP 11253 和 HIP 14929 构建全新的轨道。GJ 3076 的轨道由于受测量值权重的较大影响而无法精确构建。根据哈特科普夫（W.I. Hartkopf）、梅森（B.D. Mason）和沃利（C.E. Worley）提出的分级方案，对得到的轨道解进行了分类；大多数轨道是 "确定的"（1级）。对所研究天体的质量总和以及利用希帕尔科斯视差和盖亚 DR2 和 DR3 视差通过两种独立方法计算出的各部分质量进行了比较。
