galactic binary

(system of two object co-orbiting within the Milky Way)

The term galactic binary is used for a binary pair of objects (co-orbiting) within the Milky Way, the term typically used when discussing particular types of binaries such as compact object binaries. Typical (e.g., main-sequence) binary stars are generally studied within the Milky Way, and the term galactic binary is generally used for binaries sometimes studied at inter-galactic distances, e.g., black hole mergers, now observed through GW detections.
