Variables in S-PLUS: I. Multiband period-luminosity relations and reddening maps of the Magellanic Clouds using classical Cepheids
Debasish Hazarika, Carlos E. Ferreira Lopes, Márcio Catelan +12
Aims. Classical Cepheids (CCs) are fundamental standard candles for the extragalactic distance scale through their period-luminosity (P-L) relations. Although well calibrated in br…
The PGPUC horizontal branch evolutionary tracks
A. A. R. Valcarce, M. Catelan, S. Alves +1
The horizontal branch (HB) phase of stellar evolution plays a critical role in understanding the life cycle of stars, particularly in the context of low-mass stars. However, genera…
Relative evolution of eclipsing binaries: A tool to measure globular cluster ages and He abundances
N. Cristi-Cambiaso, M. Catelan, A. A. R. Valcarce +1
Globular clusters (GCs) are among the oldest objects in the Universe for which an age can be directly measured, thus playing an important cosmological role. This age, on the other…
Alert Classification for the ALeRCE Broker System: The Light Curve Classifier
P. Sánchez-Sáez, I. Reyes, C. Valenzuela +23
We present the first version of the ALeRCE (Automatic Learning for the Rapid Classification of Events) broker light curve classifier. ALeRCE is currently processing the Zwicky Tran…
Humps and bumps: The effects of shocks on the optical light curves of fundamental-mode RR Lyrae stars
Z. Prudil, I. Dékány, R. Smolec +3
We present the most extended and homogeneous study carried out so far of the main and early shocks in 1485 RR~Lyrae stars in the Galactic bulge observed by the Optical Gravitationa…
An AO-assisted variability study of four globular clusters
R. Salinas, R. Contreras Ramos, J. Strader +4
The image subtraction technique applied to study variable stars in globular clusters represented a leap in the number of new detections, with the drawback that many of these new li…
