摘要:

给出了主序近距离视双星系统HIP 1,105947的理想物理和几何参数。这些参数已经使用Al-Wardat的复杂方法来分析CVBS,这是一种方法,用于构建一个合成的光谱能量分布(SED)的整个双星系统使用单独的SED为每个组成星。它又使用Kurucz({ \fontfamily{cmtt} \selectfont ATLAS 9})线覆盖平面平行模型建造。同时,为了构造干涉双星系统的最佳轨道,利用Tokovinin动力学方法计算了系统的轨道参数。介绍了系统的Hessel、组分质量和、$\triangleθ$和$\triangleρ$残差。Al-Wardat和Tokovinin的方法的组合产生的物理和几何参数的最佳值的估计。绘制了系统各组分在演化轨迹和等时线上的位置,讨论了它们的形成和演化。

英文摘要:

The perfect physical and geometrical parameters of the main-sequence close visual binary system (CVBS), HIP\,105947, are explicitly presented. These parameters have been constructed conclusively using Al-Wardat's complex method for analyzing CVBSs, which is a method for constructing a synthetic spectral energy distribution (SED) for the entire binary system using individual SED for each component star. Which in its turn built using Kurucz ({\fontfamily{cmtt}\selectfont ATLAS9}) line-blanketed plane-parallel models. At the same time, the orbital parameters for the system are calculated using Tokovinin's dynamical method for constructing the best orbits of the interferometric binary system. Henceforth, the mass-sum of the components, the $\triangleθ$ and $\triangleρ$ residuals for the system are introduced. The combination of Al-Wardat's and Tokovinin's methods yields the estimation of the physical and geometrical parameters to their best values. The positions of the components of the system on the evolutionary tracks and isochrones are plotted, and their formation and evolution are discussed.
