Cataclysmic variables (CVs) are binary star systems consisting of a white dwarf and a normal star companion. They irregularly increase in brightness by a large factor, then drop back down to a quiescent state. Although over 140 polars have been detected to date, only 33 of them have been identified as eclipsing systems. Observations of these rare objects could offer astronomers more opportunities to study magnetic accretion in binaries, for instance.
