轨道双星的星表、参数和分布

Catalogues, parameters and distributions of orbital binaries

Oleg Malkov, Dmitry Chulkov

摘要:

编制了已知轨道要素的最完整的目视双星系统列表。它基于OARMAC和ORB 6数据,包含2278对3139个轨道。还汇编了一个精确的具有可用距离的高质量轨道子集。建立了不同观测参数之间的关系和沿不同观测参数的分布,并对选择效应进行了分析。动力学,光度和光谱系统的质量估计,并讨论了它们之间的差异的原因。

英文摘要:

The most complete list of visual binary systems with known orbital elements is compiled. It is based on OARMAC and ORB6 data and contains 3139 orbits for 2278 pairs. A refined subset of high quality orbits with available distance was also compiled. Relations between and distributions along different observational parameters are constructed, and an analysis of selection effects is made. Dynamical, photometric and spectral masses of systems are estimated, and reasons for discrepancies between them are discussed.
