| 英文摘要 | High-quality three-color light curves of the binary FG Gem were measured and analyzed. A new method based on extensive searching of isochrones was used to investigate possible parameters for the binary. FG Gem is found to be an Algol-type semi-detached binary system with a primary star temperature of 8200 K and a mass ratio of 0.41(1). The correctness and reliability of our result requires the verification of precision spectroscopy or standard star observations. We investigate a new possible cause for the orbital period variations based on times of minimum light data. It is suggested from the quantitative analysis that variations in the orbital period can be explained by intermittent mass transfer and angular momentum loss from stellar winds leaving the system on rotating magnetic fields. |
