好奇变量实验（CURVE）。RZ LMi -最活跃的SU Uma星
Curious Variables Experiment (CURVE). RZ LMi - the most active SU UMa star
摘要：
我们报告了频繁爆发的矮新星小狮子座RZ的广泛测光。在两个季节的观测中，我们发现了12个超级爆发和7个正常爆发。这颗恒星的V星等在16.5到13.9等之间变化，超级爆发每19.07（4）天发生一次，持续时间略超过10天。连续两次正常喷发的平均间隔时间为4.027（3）天。超爆发期间观测到的平均超峰周期为0.059396（4）天（85.530（6）分钟）。除了一次超级爆发的周期以$\dot P/P_{\rm sh} = 7.6(1.9)\cdot 10^{-5}$的速率增加外，超级峰的周期是恒定的。我们的观察表明，RZ LMi进入长时间的间隔，显示永久的超级驼峰，观察到在超级爆发和平静。这可能表明，热不稳定性和潮汐不稳定性的解耦在ERUMa系统中起着重要的作用。由于没有观测到与双星轨道周期相关的周期性光变，因此RZ LMi的质量比和演化状态仍然未知。
英文摘要：
We report extensive photometry of the frequently outbursting dwarf nova RZ Leo Minoris. During two seasons of observations we detected 12 superoutbursts and 7 normal outbursts. The V magnitude of the star varied in range from 16.5 to 13.9 mag. The superoutbursts occur quite regularly flashing every 19.07(4) days and lasting slightly over 10 days. The average interval between two successive normal outbursts is 4.027(3) days. The mean superhump period observed during the superoutbursts is 0.059396(4) days (85.530(6) min). The period of the superhumps was constant except for one superoutburst when it increased with a rate of $\dot P/P_{\rm sh} = 7.6(1.9)\cdot 10^{-5}$. Our observations indicate that RZ LMi goes into long intervals of showing permanent superhumps which are observed both in superoutbursts and quiescence. This may indicate that decoupling of thermal and tidal instabilities play important role in ER UMa systems. No periodic light variations which can be connected with orbital period of the binary were seen, thus the mass ratio and evolutionary status of RZ LMi are still unknown.
