Comprehensive study of a neglected contact binary TYC 5532-1333-1
, 2020A comprehensive photometric and spectroscopic analysis of the variable TYC 5532-1333-1 (TYC) along with an investigation of its orbital period variation is presented for the first time.

A near‐contact binary: CN Andromedae
Astronomische Nachrichten, 2005AbstractNew BVR light curves and photometric analysis of the eclipsing binary star CN And are presented. The shape of the light curves are typical of β Lyr type, and there are large asymmetries between maxima. The BVR light curves and the radial velocity curves (from Rucinski et al. 2000) were solved with the Wilson‐Devinney method, simultaneously. The

Composite contact of binary lipid membranes
The European Physical Journal E, 2013Upon adhesion, binary lipid membranes may retain their structural identity but they may also undergo partial fusion promoted by microscopic phase separation of the components. In membranes composed of cylindrical and inverted conical lipids, a partially fused contact zone may consist of inverted micelles sandwiched between two monolayers.

V1005 Her: a solar-type shallow-contact binary in a triply fossil system
Monthly notices of the Royal Astronomical Society, 2019Four sets of complete multicolour light curves of the short-period solar-type eclipsing binary V1005 Her are presented. It is found that the depth of the primary minima in the light curves went deeper from 2013 to 2018, and then became shallower again in

Contact Binaries: The Current State
AIP Conference Proceedings, 2010Lucy’s model of contact binaries has been serving well since its development in 1968 as an excellent conceptual framework for internal structure and evolution studies of the W UMa type stars. Its over‐constrained structural demands were recognized early, but—from the observational point of view—it was particularly appealing in its ability to explain W ...

1990
A group of close binary stars named near-contact binaries is defined. They are divided according to their physical characteristics into to two subclasses: V1010 Ophiuchi binaries and FO Virginis binaries. A list of members of the group, their current observational status, and their physical and evolutionary relationship to W Ursa-Majoris binaries is ...

KR Cygni: a near-contact eclipsing binary?
Astrophysics and Space Science, 2004In this study we present photometric observations of the eclipsing binary KR Cyg made in 1999 and 2000. The observations of the eclipsing binary KR Cyg have been carried out in B, V and R colours at the Ege University Observatory. A new seasonal light curves are presented. New times of minima and ephemerides are given.

Nearly Contact Binary HD 17514
1969This system was discovered in 1967 at the Crimean Observatory. Light and radial velocity curves were obtained. The star is an eclipsing binary with elliptical components. The masses of the components are 48 and 13.5 9JIq, the stars almost fill the Roche’s surface.

Evolutionary stage of contact binaries
Chinese Astronomy and Astrophysics, 1988A new method of estimating the evolutionary stage reached by a contact binary from its observations is proposed. Application to 38 systems shows that all systems of subtype A and some systems of subtype W are evolved systems, from systems which may or may not be contact systems at the zero-age main-sequence stage.
