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 by 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 $M_{1} = 1.088 \pm 0.016$ and $M_{2} = 0.883 \pm 0.016 M_{⊙}$ ; and those of ASAS J011416+0426.4 were determined to be $M_{1} = 0.934 \pm 0.046$ and $M_{2} = 0.754 \pm 0.043 M_{⊙}$ ; those of MW Aur were derived to be $M_{1} = 2.052 \pm 0.196$ and $M_{2} = 1.939 \pm 0.193 M_{⊙}$ . At last, the evolutionary status of these detached binaries was discussed based on their absolute parameters and the theoretical stellar models.
