Abstract

The paper presents light curve solutions of our observations of four new ultrashort-period eclipsing binaries with MS components. Two of them have periods almost at the upper limit (0.22 days) of the ultrashort-period binaries, while the periods of around 0.18 days of CSS J171508.5+350658 and CSS J214633.8+120016 are amongst the shortest known orbital periods. CSS J171410.0+ 445850, CSS J214633.8+120016 and CSS J224326.0+154532 are over contact binaries with fill out factors around 0.25 while CSS J171508.5+350658 is a semidetached system. The two targets with shortest periods consist of M dwarfs.

四个超短周期双星的观测及光曲线解

本文给出了我们观测到的四个新的具有质谱分量的超短周期食双星的光曲线解。其中两个的周期几乎是超短周期双星的上限(0.22天)，而CSS J171508.5+350658和CSS J214633.8+120016的周期约为0.18天，是已知最短的轨道周期之一。CSS J171410.0+ 445850, CSS J214633.8+120016和CSS J224326.0+154532是过接触二进制，填充因子在0.25左右，而CSS J171508.5+350658是一个半独立的系统。周期最短的两个目标由M个矮星组成。
