Evolutionary Effects in Contact Binaries [PDF]
International Astronomical Union Colloquium, 1982 The structure and evolution of contact binaries is an extremely difficult problem in theoretical astrophysics.Several attempts have been made to set up a satisfactory model, see e.g. Lucy,1976, Flannery, 1976, Shu, Lubow and Anderson, 1976, Robertson and Eggleton, 1977, Rahunen and Vilhu, 1977 and others.

Photometric investigation of the K-type extremely shallow contact binary V1799 Orion [PDF]
, 2014 New multi-color light curves of the very short period K-type eclipsing binary V1799 Ori were obtained and analyzed with the Wilson-Devinney code. The photometric solutions reveal that the system is a W-type shallow-contact binary with a mass ratio of q =

Photometric Studies of the Contact Binary BV Draconis [PDF]
Journal of Astronomy and Space Sciences, 1999 We performed CCD photometric observations of W UMa type contact binary BV Dra during eight nights from May 1996 to June 1999 using 61cm telescope at Sobaeksan Optical Astronomy Observatory, and completed BVR light curves of the system.

SDSS J001641-000925: THE FIRST STABLE RED DWARF CONTACT BINARY WITH A CLOSE-IN STELLAR COMPANION
, 2015 SDSS J001641-000925 is the first red dwarf contact binary star with an orbital period of 0.19856 days that is one of the shortest known periods among M-dwarf binary systems. The orbital period was detected to be decreasing rapidly at a rate of .

THE FIRST PHOTOMETRIC ANALYSIS OF THE NEAR CONTACT BINARY IR Cas [PDF]
, 2014 The first photometric analysis of IR Cas was carried out based on the new observed BVRI light curves. The symmetric light curves and nearly flat secondary minimum indicate that very precise photometric results can be determined. We found that IR Cas is a

Orbital Modulation Induced by a Third Component in the Overcontact Binary V0554 Dra
The Astrophysical JournalWe present the first comprehensive photometric and spectroscopic analysis of the overcontact eclipsing binary V0554 Dra. By simultaneously modeling multiband light curves and radial velocity data using the Wilson–Devinney code, we determine that the ...
