在2010年周期性新星U天蝎座爆发期间BVRcIc光度演化和闪烁
BVRcIc photometric evolution and flickering during the 2010 outburst of the recurrent nova U Scorpii
摘要：
介绍了2010年周期性新星U Scorpii爆发的CCD BVRcIc光度观测结果。光变曲线发展平稳，t2（V）=1.8，t3（V）=4.1天，接近1999年大爆发的t2（V）=2.2，t3（V）=4.3天。2010年的平台期比1999年的爆发更亮，持续时间更短，开始时间更早。闪烁，$I_{\rm C}$的振幅是$B$带的两倍，在第+4.8天和+15.7天不存在，在第+11.8天存在，时间尺度约为半小时。
英文摘要：
CCD BVRcIc photometric observations of the 2010 outburst of the recurrent nova U Scorpii are presented. The light-curve has a smooth development characterized by t2(V)=1.8 and t3(V)=4.1 days, close to the t2(V)=2.2 and t3(V)=4.3 days of 1999 outburst. The plateau phase in 2010 has been brighter, lasting shorter and beginning earlier than in the 1999 outburst. Flickering, with an amplitude twice larger in $I_{\rm C}$ than in $B$ band, was absent on day +4.8 and +15.7, and present on day +11.8, with a time scale of about half an hour.
