The A-type systems are shown to be evolved, having lower densities and angular momenta than the W-type systems. A new class of contact binary is identified: the OO Aquilae systems, members of which have evolved into We review and contrast two current theories for the structure of contact binary stars: discontinuity theory and thermal relaxation oscillation theory. We find that the two theories are 2019-01-01 · According to the popular view of the stellar evolution and structure of contact binary stars contact system evolve from detached systems to semi-detached and then finally to contact state (de Loore, Doom, 1992, Sahade, McCluskey, Kondo, Liu, Qian, Xiong, 2018, Goderya, Leung, Schmidt, 1996).
