DP Leonis (abbreviated DP Leo) is an eclipsing binary system approximately 1304 light-years away from the Sun, probably a cataclysmic variable star of the AM Herculis-type also known as polars. The system comprises an eclipsing white dwarf and red dwarf in tight orbit (nearly 1.5 hours) and an extrasolar planet.
Planetary system
In 2010, Qian et al. announced the detection of a third body of planetary mass around the eclipsing binary system. The presence of a third body had already been suspected in 2002. The object is roughly 6 times more massive than Jupiter and is located 8.6 AU from the binary.
