Abstract
We present the results of our photometric and spectroscopic observations. We have studied four cataclysmic variable stars: 2XMM J183251.4-100106, MLS1809017 J224712+461815, MGAB-V330, and MGAB-V410. We have analyzed the observational data and determined the periods of the systems from our photometric data. The object MLS1809017 J224712+461815 has been classified as an SU UMa-type dwarf nova. The remaining three systems are eclipsing ones, with 2XMM J183251.4-100106 and MGAB-V410 showing signatures of polars. At the same time, for MGAB-V410 the orbital period \(P_{\textrm{orb}}=2\overset{\textrm{h}}{.}2\) falls into the period gap for cataclysmic variables.
