Investigation of a W UMa-type contact binary GZ And in a physical triple system
Frontiers in Astronomy and Space SciencesGZ And is a variable star within the visually observed multiple-star system ADS 1693. Recent observations have yielded new light curves for GZ And, obtained using the Xinglong 85-cm telescope and the Transiting Exoplanet Survey Satellite (TESS) satellite.

Study on the physical parameters of 18 contact binary stars
Monthly Notices of the Royal Astronomical SocietyABSTRACT We present the photometric light curve solutions of 18 W Ursae Majoris-type contact binary stars with orbital periods shorter than 0.5 d. This investigation utilized photometric data from the Transiting Exoplanet Survey Satellite, Gaia, and the All Sky Automated Survey for SuperNovae.

Masses and angular momenta of contact binary stars [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2006 Abstract Results are presented on component masses and system angular momenta for over 100 low-temperature contact binaries. It is found that the secondary components in close binary systems are very similar in mass. Our observational evidence strongly supports the argument that the evolutionary process goes from near-contact binaries to

Detection and Seismic Study of Gravity and Rossby Mode Pulsations in Four Contact Binaries
The Astrophysical Journal, 2023 We report the detection of gravity ( g ) and Rossby ( r ) mode pulsations of four short-period eclipsing binaries, KIC 5439790, KIC 7501230, KIC 9350889, and KIC 9453192 based on the 4 yr Kepler high-precision photometry.

International Astronomical Union Colloquium, 1983 Abstract:Ultraviolet and X-ray surveys of the W Ursae Majoris type stars are reviewed. These systems exhibit extended coronas and transition regions that are confined close to the optically determined surfaces. Correlations of X-ray activity with period or rotational velocity indicate a turn-over or saturation of emission at the short periods or high ...

Photometric study of contact binary star MW And [PDF]
New Astronomy, 2019 The Tarleton Observatory's 0.8m telescope and CCD photometer were used to obtain 1298 observations of the short period eclipsing binary star MW And. The observations were obtained in Johnson's BVR filters. The light curves show that MW And is an eclipsing binary star with a period of 0.26376886 days. Further analysis showed that the period of MW And is

The evolution of binary stars into contact states [PDF]
Space Science Reviews, 1989 AbstractGood-quality empirical results on 62 short-period binary stars recently summarised by Hilditch & Bell (1987) and Hilditch, King & McFarlane (1988) are discussed in terms of evolutionary paths from detached to semi-detached and contact states.
