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.

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

A Model for Contact Binary Systems
Chinese Journal of Astronomy and Astrophysics, 2007A model for contact binary systems is presented, which incorporates the following special features: a) The energy exchange between the components is based on the understanding that the energy exchange is due to the release of potential, kinetic and thermal energies of the exchanged mass.

Multiplicity of Contact Binary Stars
2007We present results of a preliminary investigation of triple star incidence for contact binary stars. The goal is to shed light on the possible role of distant companions which may have acquired and/or absorbed AM during evolution of multiple systems facilitating or enabling formation of contact binaries.

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.

The observations of Sistero and Sistero are reanalyzed. HD 101799 is found to be a contact system instead of semidetached as reported previously. New absolute dimensions for the components are derived. The secondary (less massive component) is found to be cooler and larger than believed earlier. Based on the size of the radius of the primary the binary

Activity of Contact Binary Systems
1985This review will consider various indicators of activity in contact binaries. We shall limit ourselves to late-type contact systems which are traditionally called the “W UMa-type” systems. This limitation results mainly from a better knowledge of properties of cooler systems (i.e.
