| 英文摘要 | The mid-eclipse times obtained using TESS data for the semidetached binary V527 Dra show cyclic variations attributed to the presence of an additional body. Additionally, the broadening profiles (BFs) of V527 Dra, obtained from spectroscopic data gathered between 2020 and 2024, reveal a third peak with varying radial velocities over time, further indicating the presence of a third body. Therefore, in this study, using the radial velocity variations of the third component and the eclipse timing variations from the TESS data, we were able to constrain the orbital parameters of the third component. |
