Energy Optimization in Binary Star Systems: Explanation for Equal Mass Members in Close Orbits

23 Mar 2020 Adams Fred C. Batygin Konstantin Bloch Anthony M.

Observations indicate that members of close stellar binaries often have mass ratios close to unity, while longer-period systems exhibit a more uniform mass-ratio distribution. This paper provides a theoretical explanation for this finding by determining the tidal equilibrium states for binary star systems --- subject to the constraints of conservation of angular momentum and constant total mass...
