OBSERVED PROPERTIES OF CONTACT BINARY SYSTEMS
Odessa Astronomical Publications, 2017 A group of close eclipsing systems, which continues to pose a challenge in many subjects of modern astrophysics, is that of contact binaries. In this study, using the most recent observational data of a large sample of such systems, a review concerning ...

On the properties of contact binary stars
, 2004 A catalogue of light curve solutions of contact binary stars has been compiled. It contains the results of 159 light curve solutions. Properties of contact binary stars were studied by using the catalogue data. As it is well known since Lucy's (1968a,b)

Detection of Contact Binaries Using Sparse High Phase Angle Lightcurves
, 2007 We show that candidate contact binary asteroids can be efficiently identified from sparsely sampled photometry taken at phase angles >60deg. At high phase angle, close/contact binary systems produce distinctive lightcurves that spend most of the time at ...

Two Massive Twins in a Deep-contact Binary with a Black Hole Candidate
Astrophysical Journal, 2019 New light curves in B, V, R, and I bands for the B-type contact binary V593 Cen were obtained, and another V-band light curve was collected from All Sky Automated Survey data. We analyzed these two sets of light curves using the Wilson–Devinney code.

Physical properties and evolutionary status of the W-subtype contact binary V502 Oph with a stellar companion [PDF]
, 2016 Multi-color ($B$ $V$ $R_c$ $I_c$) CCD photometric light curves of the contact binary V502 Oph are analyzed using the Wilson-Devinney (W-D) program. The solutions reveal that V502 Oph is a W-subtype contact ($f = 35.3\,\%$) binary system.

A SOLAR-TYPE STELLAR COMPANION TO A DEEP CONTACT BINARY IN A QUADRUPLE SYSTEM [PDF]
, 2016 The four-color (B, V, Rc, Ic) light curves of V776 Cas are presented and analyzed using the Wilson–Devinney method. It is discovered that V776 Cas is an early F-type (F2V) overcontact binary with a very high contact degree (f = 64.6%) and an extremely ...

A ROSAT Survey of Contact Binary Stars
, 2005 Contact binary stars are common variable stars which are all believed to emit relatively large fluxes of x-rays. In this work we combine a large new sample of contact binary stars derived from the ROTSE-I telescope with x-ray data from the ROSAT All-Sky ...

CN Andromedae: a shallow contact binary with a possible tertiary component
Research in Astronomy and Astrophysics, 2019 In this study, new photometric observations of shallow contact binary CN Andromedae (CN And) were performed and multi-color (BV R) CCD light curves (LCs) were obtained. Simultaneous analysis of new LCs and published radial velocity (RV) data reveals that

Photometric Observations of the Contact Binary System V523 Cassiopeiae [PDF]
Journal of Astronomy and Space Sciences, 2006 A total of 920 observations (230 in Delta B, 230 in Delta V, 230 in Delta R, 230 in Delta I) for V523 Cas were made on 5 nights from January 6 to 24 in 2003 using the 61cm telescope with 2K CCD camera of the Sobaeksan Optical Astronomy Observatory of ...
