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…
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…
