摘要

我们提出了a型wuma双星GSC 3208 1986的一个新的周期研究和光曲线解。与R.G. Samec等人先前提出的周期迅速减少的说法相反，该系统的周期在200万年的时间尺度上是适度增加的。光曲线在年的时间尺度上是可变的，这可以通过它填满罗氏叶的程度的变化来理解。

CCD Minima for Selected Eclipsing Binaries in 2018

We present a new period study and light-curve solutions for the A-Type W UMa binary GSC 3208 1986. Contrary to a previous claim by R.G. Samec et al. of a rapidly decreasing period, the system's period is increasing moderately on a timescale of two million years. The light curve is variable on the time scale of years, which can be understood by changes in how much it overfills its Roche lobe.
