Contact Binaries

, 2003
Despite being the most abundant (by space density) of interacting binary stars, W Ursae Majoris (W UMa) stars are not understood structurally. Their stellar components are in physical contact, and share a common convective envelope. Observations demand large-scale energy exchange between components, as do considerations of hydrostatic and thermal ...

GY Tel: a new thermally decoupled near contact binary system [PDF]

, 2022
GY Tel is a short period (0.446 d) eclipsing binary system of 12th magnitude showing a large difference(0.85 mag) in the depths of minima. The first UBV observations obtained at Bosque Alegre (Córdoba) and at CASLEO (San Juan) are presented.
