High-cadence stellar variability studies of RR Lyrae stars with DECam: New multi-band templates

K. Baeza-Villagra, N. Rodriguez-Segovia, M. Catelan +6

We present the most extensive set to date of high-quality RR Lyrae light curve templates in the griz bands, based on time-series observations of the Dark Energy Camera Plane Survey…

The VVV survey: Long-period variable stars I. Photometric catalog of ten VVV/OGLE tiles

F. Nikzat, C. E. Ferreira Lopes, M. Catelan +7

Long-period variable stars (LPVs) are pulsating red giants, primarily in the asymptotic giant branch phase, and they include both Miras and semi-regular variables (SRVs). Their per…

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…

Search for magnetic accretion in SW Sextantis systems

I. J. Lima, C. V. Rodrigues, C. E. Ferreira Lopes +9

SW Sextantis systems are nova-like cataclysmic variables that have unusual spectroscopic properties, which are thought to be caused by an accretion geometry having part of the mass…

VVV survey near-infrared colour catalogue of known variable stars

Fábio R. Herpich, Carlos E. Ferreira Lopes, Roberto K. Saito +4

Context. The Vista Variables in the Via Lactea (VVV) near-infrared variability survey explores some of the most complex regions of the Milky Way bulge and disk in terms of high ext…

Recovering variable stars in large surveys: EA Algol-type class in the Catalina Survey

A. Carmo, C. E. Ferreira Lopes, A. Papageorgiou +5

The discovery and characterization of Algol eclipsing binaries (EAs) provide an opportunity to contribute for a better picture of the structure and evolution of low-mass stars. How…
