A Unique Low-Mass Ratio Contact Eclipsing Binary System under the Period Cut-Off
A. Papageorgiou, P. -E. Christopoulou, E. Lalounta +5
We present a multi-band photometric analysis of CRTS J163819.6+03485, the first low mass ratio (LMR) contact binary system with a period under the contact binary (CB) period limit.…
Three Ultra-short Period Contact Eclipsing Binary Systems Mined from Massive Astronomical Surveys
A. Papageorgiou, P. -E. Christopoulou, C. E. Ferreira Lopes +3
We present the photometric analysis of three ultra-short period total eclipsing binaries in contact configuration, CRTS_J172718.0+431624, OGLE-BLG-ECL-000104, and OGLE-BLG-ECL-0000…
New low mass ratio contact binaries in the Catalina Sky Survey
P. E. Christopoulou, Eleni Lalounta, Athanasios Papageorgiou +3
We present the identification and photometric analysis of 30 new low mass ratio (LMR) totally eclipsing contact binaries found in Catalina Sky Survey data. The LMR candidates are i…
The VVV Infrared Variability Catalog (VIVA-I)
C. E. Ferreira Lopes, N. J. G. Cross, M. Catelan +17
Thanks to the VISTA Variables in the Via Lactea (VVV) ESO Public Survey it is now possible to explore a large number of objects in those regions. This paper addresses the variabili…
An Updated Catalog of 4680 Northern Eclipsing Binaries with Algol-Type light curve morphology in the Catalina Sky Surveys
A. Papageorgiou, M. Catelan, P. -E. Christopoulou +2
We present an updated catalog of 4680 northern eclipsing binaries (EBs) with Algol-type light curve morphology (i.e., with well-defined beginning and end of primary and secondary e…
