论文摘要
我们介绍了UBVR频段中AM CVN星CR Boo的观察结果。我们的观察活动包括与国家天文天文台Rozhen，Belogradchik和AS Vidojevica望远镜一起获得5晚的数据。在我们观察的整个过程中，系统的亮度在$ 13.95-17.23 $之间变化。我们报告在物体的活跃状态（在两晚中检测到后者）期间的静止状态和超烟期期间出现驼峰。我们获得了两个晚上的超级峰期周期性，$ p_ {sh} \大约24.76-24.92 $ min。最大亮度期间的颜色估计为$ -0.107 <（b-v）_ {0} <0.257 $，相应的温度在$ 7700 [k] <t（b-v）_ {0} <11700 [k] $中。我们发现，随着爆发活动的夜晚，CR Boo从蓝色到红色。在超级雨期期间，恒星变得更加蓝。
We present our observational results of AM CVn star CR Boo in the UBVR bands. Our observational campaign includes data obtained over 5 nights with the National Astronomical Observatory Rozhen, Belogradchik and the AS Vidojevica telescopes. During the whole time of our observations the brightness of the system varied between $13.95 - 17.23$ in B band. We report the appearance of humps during the period of quiescence and superhumps during the active state of the object, (where the latter are detected in two nights). We obtain the superhumps periodicity for two nights, $P_{sh}\approx 24.76 - 24.92$ min. The color during maximum brightness is estimated as $ - 0.107 < (B-V)_{0} < 0.257$ and the corresponding temperature is in the range as $7700 [K] < T(B-V)_{0} < 11700 [K]$. We found that CR Boo varies from bluer to redder in the nights with outbursts activity. The star becomes bluer during the times of superhumps.
