Absolute physical parameters of three poorly studied detached eclipsing binaries

Year: 2021

Type: article

Abstract: The photometric and spectroscopic data for three double-lined detached eclipsing binaries were collected from the photometric and spectral surveys. The light and radial velocity curves of each binary system were simultaneously analyzed using Wilson-Devinney (WD) code, and the absolute physical and orbital parameters of these binaries were derived. The masses of both components of ASASSN-V J063123.82+192341.9 were found to be M 1 = 1.088 ± 0.016 and M 2 = 0.883 ± 0.016 M ⊙ ; those of ASAS J011416+0426.4 were determined to be M 1 = 0.934 ± 0.046 and M 2 = 0.754 ± 0.043 M ⊙ ; and those of MW Aur were derived to be M 1 = 2.052 ± 0.196 and M 2 = 1.939 ± 0.193 M ⊙ . Finally, the evolutionary status of these detached binaries was discussed based on their absolute parameters and the theoretical stellar models.
