DQ Herculis

[7] The system shows orbital period variation, possibly due to the presence of a third body.

[8] DQ Herculis is the prototype for a category of cataclysmic variable stars called intermediate polars.

[5] The red dwarf has filled its Roche lobe and matter is being drawn off at the rate of 2.7 × 10−9 M☉ yr−1, forming an accretion disk orbiting the primary.

In addition to scientific articles, and received significant coverage in popular news publications.

[14][15] Brad Ricca, an English professor at Case Western Reserve University, has suggested that Nova Herculis may have influenced the development of the origin story of the comic book superhero Superman.
