These entities can undergo gas accretion caused by Roche lobe overflow; in 2004, it was discovered that these led to the 1572 supernova studied by Tycho Brahe.

Pinwheel nebulae can form around these objects, and the discovery of one of these systems, consisting of pulsars, won the 1993 Nobel in Physics for Hulse and Taylor. Studying the Doppler shift of spectral lines can allow discovery of spectroscopic types of these, while other types include astrometric and eclipsing. Name this type of celestial system, the most famous example of which consists of Sirius A and Sirius B rotating around the pair's center of mass.
