用TESS观测的几个半分离系统的分析

Analysis of some Semi-Detached systems observed by TESS

Fahri Alicavus

摘要:

半分离双星系统是精确测定天体物理参数、分析组分间质量传递和损失机制的重要系统。在这项研究中,一些半分离系统(RV Pic和AS Eri)的光变曲线分析,其中光变化是由凌日系外行星调查卫星(TESS),进行。得到了系统的天体物理参数。此外,还研究了系统的振荡性质,讨论了这类恒星的质量转移和损失量,并与观测数据进行了比较。

英文摘要:

Semi-Detached binary stars are very important systems for the precise determination of astrophysical parameters and the analysis of mass transfer and loss mechanisms between the components. In this study, the light curve analysis of some semi-detached systems (RV Pic and AS Eri), which light changes are obtained by the Transiting Exoplanet Survey Satellite (TESS), was performed. The astrophysical parameters of the systems were obtained. In addition, oscillational properties of the systems were investigated, and the mass transfer and the loss amount of such stars are discussed and compared with observational data.
