dc.description.abstract | Photometric observations were made with standard filters in four observatories for 10 contact binary systems. We analyzed the orbital period variations of the systems and found that six of them show long-term changes. The increase in the orbital period of the J07, N65, and PU Vir systems is caused by mass transfer, and the reduction in the orbital period of the J05, LO Psc, and N49 systems is caused by the combination of angular momentum loss and mass transfer. The first light-curve analysis was performed with the PHysics Of Eclipsing BinariEs Python code and Markov Chain Monte Carlo. We discussed the accuracy of photometric mass ratio estimates for contact binary systems with total and partial eclipses compared to spectroscopic results. We also compared our mass ratio findings to a recent method that estimates mass ratios from the light curve's third derivative. Then, we also discussed this new mass ratio estimate method for photometric data. The systems' positions were displayed in 18 empirical parameter relationships. According to the light-curve analysis and estimation of absolute parameters, systems BE Mus, J07, J08, N49, and N65 are A subtypes, and the others are W subtypes. | |

dc.description.sponsorship | This manuscript was prepared by the BSN project. Work by K.L. was supported by the National Natural Science Foundation of China (NSFC; No. 12273018) and by the Qilu Young Researcher Project of Shandong University. Ground-based observations of four systems were conducted with the cooperation of the Observatorio Astronomico Nacional on the Sierra San Pedro Martir (OAN-SPM), Baja California, Mexico. We used IRAF, which is distributed by the National Optical Astronomy Observatories and operated by the Association of Universities for Research in Astronomy, Inc., under a cooperative agreement with the National Science Foundation. We used data from the European Space Agency's mission Gaia. 20 20 http://www.cosmos.esa.int/gaia This work includes data from the TESS mission observations. The NASA Explorer Program provides funding for the TESS mission. This paper used some results from the American Association of Variable Star Observers (AAVSO 21 21 https://www.aavso.org/ ). We appreciate the helpful comments from Shinjirou Kouzuma, Edwin Budding, and Ehsan Paki. Finally, we thank the referee for help in improving the paper. | |
