Observational Constraints on Close Binary Star Evolution. I. Putative Contact Binaries with Long Periods and High Mass Ratios

Evolutionary and structural models for contact binary stars make quantitative predictions about the distribution of systems in the mass ratio ( q )–orbital period ( P ) plane. Specifically, contact binaries containing primaries with convective envelopes are predicted to be absent at mass ratios larg...
