Contact binaries consist of two strongly interacting component stars where they are filling
their critical Roche lobes and sharing a common envelope. Most of them are main-sequence …

High precision CCD observations of six totally eclipsing contact binaries were presented
and analyzed. It is found that only one target is an A-type contact binary (V429 Cam), while …

Time-related binary system characteristics such as orbital period, its rate of change, apsidal
motion, and variable light-time delay due to a third body, are measured in two ways that can …

DEEP, LOW MASS RATIO OVERCONTACT BINARY SYSTEMS. XIV. A STATISTICAL
ANALYSIS OF 46 SAMPLE BINARIES - IOPscience Skip to content IOP Science home …

Secondary components of W UMa-type contact binaries (CBs) have many special
properties, two of them are excess in radius and luminosity. In order to make these …

Theoretical study indicates that a contact binary system would merge into a rapidly rotating
single star due to tidal instability when the spin angular momentum of the system is more …

This is the first of a series of four papers, the goal of which is to identify the overcontact
eclipsing binary star systems for which a solid case can be made for mass exchange. To …

CCD photometric light curves in the B and V bands obtained in 2001 and in the V band
obtained in 2002 of AH Cnc in the old open cluster M67 are presented. It is shown that AH …

Well-determined physical parameters of 130 W Ursae Majoris (W UMa) systems were
collected from the literature. Based on these data, the evolutionary status and dynamical …

Context. The observed light curves of most eclipsing binaries and stars with transiting
planets can be described well and interpreted by current advanced physical models that …
