Superhumps are a type of periodic variation in brightness observed in certain cataclysmic variable stars, primarily in an object class known as dwarf novae. These stars undergo eruptions or outbursts caused by the accumulation of material on their surface from a companion star. The term "superhump" specifically refers to a modulation in brightness that is typically slightly longer in period than the orbital period of the binary system.
