A near‐contact binary: CN Andromedae

Astronomische Nachrichten, 2005
AbstractNew 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, 2007
A 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.

Contact Binaries: The Current State

AIP Conference Proceedings, 2010
Lucy’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 ...

On evolution of contact eclipsing binaries

Astrophysics and Space Science, 1996
It is shown that during contact eclipsing binaries evolution under the influence of stellar wind, magnetic stellar wind and with matter transfer by gas flow, in binary stellar systems there may take place a process of star merger (low mass stars) within 105–107 yr and a fast increase of distance between stars of massive binaries. W UMa-type stars are a

Multiplicity of Contact Binary Stars

2007
We 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, 1988
A 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.

On the Solutions for Contact Binary Systems

1987
Although the pioneering paper of Lucy (1968) appeared already 18 years ago, the theory of contact binaries is by far not yet in a satisfactory state. This concerns in particular an aspect with which I will not deal here at all, namely the inability to reproduce theoretically the observed systems (light curves, period-colour relation).

Activity of Contact Binary Systems

1985
This 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.
