Constraints on Helium Enhancement in the Globular Cluster M4 (NGC 6121): The Horizontal Branch Test
A. A. R. Valcarce, M. Catelan, J. Alonso-García +2
Recent pieces of evidence have revealed that most, and possibly all, globular star clusters are composed of groups of stars that formed in multiple episodes with different chemical…

M. Catelan, C. Cortés
We use theoretical models to establish a tight relationship for the absolute magnitudes of RR Lyrae stars as a function of their periods and Stroemgren pseudo-color c_0 = (u-v)_0 -…
