大分子型二元系统WZ Crv的热点与传质

A Hot Spot and Mass Transfer of the Algol-type Binary System WZ Crv

Natalia A. Virnina, Ivan L. Andronov, Maxim V. Mogorean

摘要:

本文介绍了利用Tzec Maun天文台的TOA-150遥控望远镜对大陵型双星WZ Crv(12h44m15.19s,-21d25m35.4s)进行双色VR观测的结果。我们确定了各个极小值的时刻,轨道周期及其导数,初始历元,颜色指数V-R和组件的温度估计。我们还注意到,相位曲线是不对称的:第二个最大值高于第一个。它表明在这个系统中的一颗恒星的光球中有一个点。

英文摘要:

We present the results of two color VR observation of the Algol-type binary system WZ Crv (12h44m15.19s, -21d25m35.4s) which were obtained using the remotely controlled telescope TOA-150 of Tzec Maun Observatory. We determined the moments of individual minima, the orbital period and its derivative, the initial epoch, color indices V-R and temperature estimates of the components. Also we noticed that the phase curve is asymmetric: the second maximum is higher than the first one. It indicates that there is a spot in the photosphere of one of the stars in this system.
