Differential BVRI light curves of DV Psc

We present six new BVR_c_I_c_ CCD light curves of a short-period RS CVn binary DV Psc obtained in 2010-2012. The light curve distortions change on both short and long...本文报道了2010—2012年观测得到的短周期RS CVn型双星（RS CVn binary）双鱼座DV（DV Psc）的六条新的BVR_c、I_c波段CCD（电荷耦合器件）光变曲线。该光变曲线的畸变在短时间与长时间尺度上均存在变化……
