Abstract

In this study, the analysis of the Kepler light curve of the eclipsing binary KIC 10296163 (Gaia DR2 2085670964017513856, R.A.2000 = 19h564m40s.07, DEC2000 = +470 21’21”.97, mR = 13.43 mag) is presented. The light curve of the system shows a secondary minimum from a shifted phase 0.5 which indicates the ellipticity of the orbit. By using the PHOEBE program we analysed the light curve to achieve the orbital parameters of the system. The results of our analysis indicates a detached system where the orbit is highly eccentric (e = 0.357 ± 0.003). Therefore, KIC 11858541 is a suitable candidate for apsidal motion studies.In this study, the analysis of the Kepler light curve of the eclipsing binary KIC 10296163 (Gaia DR2 2085670964017513856, R.A.2000 = 19h564m40s.07, DEC2000 = +470 21’21”.97, mR = 13.43 mag) is presented.

高偏心食双星KIC 10296163的光曲线分析

本研究分析了食双星KIC 10296163 (Gaia DR2 2085670964017513856, R.A.2000 = 19h564m40s的开普勒光曲线。07, dec2000 = +470 21 ' 21 "。97, mR = 13.43 mag)。系统的光曲线显示出一个从移相0.5开始的次极小值，表明轨道的椭圆性。利用PHOEBE程序对光曲线进行分析，得到了该系统的轨道参数。我们的分析结果表明，一个分离的系统，轨道是高度偏心的(e = 0.357±0.003)。因此，KIC 11858541是一个合适的候选者，用于辅助运动研究。本研究分析了食双星KIC 10296163 (Gaia DR2 2085670964017513856, R.A.2000 = 19h564m40s的开普勒光曲线。07, dec2000 = +470 21 ' 21 "。97, mR = 13.43 mag)。系统的光曲线显示出一个从移相0.5开始的次极小值，表明轨道的椭圆性。利用PHOEBE程序对光曲线进行分析，得到了该系统的轨道参数。我们的分析结果表明，一个分离的系统，轨道是高度偏心的(e = 0.357±0.003)。因此，KIC 11858541是一个合适的候选者，用于辅助运动研究。
