论文摘要
提出了AH MIC二元系统的第一个多色光曲线分析。该系统几乎没有来自南半球的观察结果。我们基于马尔可夫链蒙特卡洛（MCMC）方法从光曲线中提取了最小时间，并获得了新的埃弗米斯。为了提供现代的光度光曲线解决方案，我们使用了黯淡的二进制文件（Phoebe）软件包和MCMC方法的物理。光曲线溶液产生的系统温度比为0.950，我们假设基于O'Connell效应的热星形恒星。该分析表明，AH MIC是W-Subtype W UMA接触系统，填充因子为21.3％，质量比为2.32。 The absolute physical parameters of the components are estimated by using the Gaia Early Data Release 3 (EDR3) parallax method to be M_h(M_Sun)=0.702(26), M_c(M_Sun)=1.629(104), R_h(R_Sun)=0.852(21), R_c(R_Sun)=1.240(28), L_H（L_SUN）= 0.618（3）和L_C（L_SUN）= 1.067（7）。发现AH MIC二元系统的轨道角动量为51.866（35）。该系统的组件位置在Hertzsprung-Russell（H-R）图中绘制。
The first multi-color light curve analysis of the AH Mic binary system is presented. This system has very few past observations from the southern hemisphere. We extracted the minima times from the light curves based on the Markov Chain Monte Carlo (MCMC) approach and obtained a new ephemeris. To provide modern photometric light curve solutions, we used the Physics of Eclipsing Binaries (Phoebe) software package and the MCMC approach. Light curve solutions yielded a system temperature ratio of 0.950, and we assumed a cold star-spot for the hotter star based on the O'Connell effect. This analysis reveals that AH Mic is a W-subtype W UMa contact system with a fill-out factor of 21.3% and a mass ratio of 2.32. The absolute physical parameters of the components are estimated by using the Gaia Early Data Release 3 (EDR3) parallax method to be M_h(M_Sun)=0.702(26), M_c(M_Sun)=1.629(104), R_h(R_Sun)=0.852(21), R_c(R_Sun)=1.240(28), L_h(L_Sun)=0.618(3) and L_c(L_Sun)=1.067(7). The orbital angular momentum of the AH Mic binary system was found to be 51.866(35). The components' positions of this system are plotted in the Hertzsprung-Russell (H-R) diagram.
