论文摘要
提出了双鱼座星座中恒星EW和HN的第一光曲线解决方案。光度法及其周期性变化是计算和讨论的。 MCMC方法在OCFIT代码中对O-C图进行的O-C图分析，以及为两个二进制系统提供的新埃弗米斯。获得的光曲线解决方案。结果表明，EW PSC分别是近接触的二进制二进制系统，具有光度质量比Q = 0.587，而对原始组件和次要组件的夹心系数分别为-0.034和-0.018。解决方案的结果还表明，系统HN PSC是一种弱接触二进制的二进制，具有光度质量比Q = 0.853，并且夹层因子为5.6％。光曲线解决方案需要对O'Connell效应进行冷点核算。
The first light curve solutions of the stars EW and HN in Pisces constellation are presented. Photometry, and its' periodic changes are calculated and discussed. The analysis of O-C diagram done by MCMC approach in OCFit code and the new ephemeris provided for two binary systems. The light curve solutions obtained. The results show that EW Psc is a near contact eclipsing binary system with a photometric mass ratio q = 0.587, and the fillout factor -0.034 and -0.018 for primary and secondary components, respectively. The solution results also show that the system HN Psc is a weak-contact W UMa eclipsing binary with a photometric mass ratio q = 0.853, and with fillout factor 5.6%. The light curves solutions required the cold spot accounting for the O'Connell effect.
