论文摘要
通过使用最新版本的W-D代码，介绍并分析了VRI Passbands光曲线。观察到的频谱表明，V344 LAC不是A3类型，而是根据产量的温度是后来的F型恒星。溶液的结果表明，V344 LAC是A-Subtype触点二进制，介导光度质量比为0.387（0.003），中介接触因子为44.6（3.0）％。基于Gaia给出的视差，组件的参数估计为：M1 = 1.16 ms，M2 = 0.45 ms，R1 = 1.31 RS，R2 = 0.88 RS，L1 = 2.512 LS，L2，L2 = 1.057 LS。该期间的研究表明，V344 LAC可能具有偏心轨道振荡，P3 = 12.4（0.5）YR，A3 = 0.0020（0.0002）D，E = 0.38（0.16）。分析表明，这种振荡将是由磁性活性引起的，可以通过Applegate机制来解释。同时，根据L3的值和V344 LAC的估计物理参数，第三个伴侣的质量可能为0.79女士。这三个机构可能是一家范围的公司。
The VRI passbands light curves of V344 Lac were presented and analyzed by using the latest version of the W-D code. The observed spectrum reveals that V344 Lac is not an A3 type but would be a later F type star according to the yielded temperature. The results of solution show that V344 Lac is an A-subtype contact binary, with a mediate photometric mass ratio of 0.387(0.003) and a mediate contact factor of 44.6(3.0)%. Based on the parallax given by Gaia, the parameters of the components are estimated as: M1 = 1.16 Ms, M2 = 0.45 Ms, R1 = 1.31 Rs, R2 = 0.88 Rs, L1 = 2.512 Ls, L2 = 1.057 Ls. The period investigation indicates that V344 Lac may have an eccentric orbital oscillation, with P3 = 12.4(0.5) yr, A3 = 0.0020(0.0002) d, and e = 0.38(0.16). Analysis shows such oscillation would be caused by a magnetic activity which can be explained by the Applegate mechanism. Meanwhile, according to the value of l3 and the estimated physical parameters of V344 Lac, the mass of the third companion may be 0.79 Ms. This third body could be a wide company.
