论文摘要
提出了二进制髋关节18856的研究结果及其轨道的构造。 2007 - 2019年在Sao Ras的BTA获得的新观察数据。较早的Cvetkovi'c等。 (2016)为该系统构建了轨道。但是,它基于6个测量值,覆盖了轨道的一小部分。河马(ESA 1997)天文卫星的位置参数发表了斑点干涉数据(Mason等,1999; Balega et al。2006,2007; Horch et al。2012,2011,2017),并在这项研究中使用了新的。根据新的轨道参数,计算了质量总和,并发现了组件的物理参数。将获得的轨道和基本参数与Cvetkovi'C等人的研究数据进行了比较。 (2016)。比较表明,新的轨道溶液比旧的溶液要好,因为它准确地拟合了新的观察数据。还基于Worley&Heintz(1983)进行的定性等级,新轨道被归类为“可靠”,这意味着数据覆盖了一半以上的轨道,并具有足够数量的测量值。
The results of the study of the binary HIP 18856 and construction of its orbit are presented. New observational data obtained at the BTA of SAO RAS in 2007-2019. Earlier Cvetkovi'c et al. (2016) constructed orbit for this system. However, it is based on 6 measurements, which cover a small part of the orbit. The positional parameters of the Hipparcos (ESA 1997) astrometric satellite, published speckle interferometric data (Mason et al. 1999; Balega et al. 2006, 2007; Horch et al. 2012, 2017) and new ones were used in this study. Based on the new orbital parameters, the mass sum was calculated, and the physical parameters of the components were found. The obtained orbital and fundamental parameters were compared with the data from the study by Cvetkovi'c et al. (2016). The comparison shows that the new orbital solution is better than the old one, since it fits new observational data accurately. Also based on the qualitative grade performed by Worley & Heintz (1983) new orbit was classified as "reliable", which means data covering more than half of the orbit with sufficient quantities of residuals of measurements.
