摘要

The evolution and outburst are two major topics in the field of cataclysmic variable stars (CVs). In this manuscript, I summarize some of the recent progresses of our research group at YNAO in two topics by monitoring nearly 50 eclipsing CVs and nearly 20 M-type short-period eclipsing binary stars for several years. Our scientific propose are: (1) understanding the evolution of CVs by statistical investigation of the changes of the orbital periods of eclipsing CVs; (2) investigating chromospheric activity on the mass-losing secondary star in CVs by monitoring the long-term variations of the light curve of some M-type eclipsing binaries (e.g., the detection of the most energetic flare observed in R-band); (3) investigating the properties of mass accretion in CVs by monitoring some magnetic CVs and then understanding physical mechanism that caused the outbursts of CVs.
