DI Herculis is a binary star system located in the constellation Hercules. It is particularly notable because it is categorized as a cataclysmic variable star system, which means it exhibits fluctuations in brightness due to the interaction between two stars—a white dwarf and a red dwarf, in this case. In a cataclysmic variable system like DI Herculis, the white dwarf accretes material from its companion star (the red dwarf).
