Contact Binary Variables as X-ray Sources [PDF]
, 2005 We present cross-identification of archived X-ray point sources with W UMa variable stars found in the All-Sky Automated Survey (ASAS). In a surveyed sky area of 300 square degrees of ASAS, 36 W UMa stars have been found associated with X-ray emission ...

YZ Phoenicis: a very short period K-type contact binary with variation of the O’Connell effect and orbital period change [PDF]
Nippon Tenmon Gakkai obun kenkyu hokoku, 2019 YZ Phe is a very short-period contact binary (Sp. = K2 V) with an orbital period of 0.2347 d near the short period limit (0.22 d). We present the complete light curves which photometric data were obtained from the 60 cm telescope of PROMPT-8 at CTIO in

Period Change of the Contact Binary AH Tauri [PDF]
Journal of Astronomy and Space Sciences, 2004 New BVRI photometric observations of the contact binary AH Tau were performed with the 61 cm reflector and a 2K CCD camera at the Sobaeksan Optical Astronomy Observatory during seven nights from September to December, 2001. A total of 144 times of minima

Low Mass Ratio Contact Binary Systems HN UMa and II UMa - III [PDF]
Journal of Astronomy and Space Sciences, 2006 We present newly observed BVRI CCD light curves for low mass ratio contact binaries, HN UMa and II UMa. The absolute dimensions of these objects were obtained by applying the Wilson-Devinney program to previously published spectroscopic analysis and to ...

CCD Photometry of Low Mass Ratio Contact Binary FP Boo - IV [PDF]
Journal of Astronomy and Space Sciences, 2009 We present new B, V, and R CCD photometric light curves for the low mass ratio contact binary FP Boo. A new photometric solution and absolute physical dimensions of the system were derived by applying the Wilson-Devinney program to our observed light ...

A low-mass-ratio and deep contact binary as the progenitor of the merger V1309 Sco [PDF]
, 2016 Nova Sco 2008 (=V1309 Sco) is an example of a V838 Mon type eruption rather than a typical classical nova. This enigmatic object was recently shown to have resulted from the merger of two stars in a contact binary. It is the first stellar merger that was
