| 英文摘要 | 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-circle dot; those of ASAS J011416+0426.4 were determined to be M-1 = 0.934 +/- 0.046 and M-2 = 0.754 +/- 0.043 M-circle dot; and those of MW Aur were derived to be M-1 = 2.052 +/- 0.196 and M-2 = 1.939 +/- 0.193 M-circle dot. Finally, the evolutionary status of these detached binaries was discussed based on their absolute parameters and the theoretical stellar models. |
