Formation rates of star clusters in the hierarchical merging scenario
(2011)
Stars form with a complex and highly structured distribution. For a smooth star cluster to form from these initial conditions, the star cluster must erase this substructure. We study how substructure is removed using N-body ...
A Hot Horizontal Branch Star With A Close K-Type Main-Sequence Companion
(2015)
Dynamical interactions in binary systems are thought to play a major role in the formation of extreme horizontal branch stars (EHBs) in the Galactic field. However, it is still unclear if the same mechanisms are at work ...
Pulsating stars in omega Centauri Near-IR properties and period-luminosity relations
(2017)
omega Centauri (NGC 5139) contains many variable stars of different types, including the pulsating type II Cepheids, RR Lyrae and SX Phoenicis stars. We carried out a deep, wide-field, near-infrared (IR) variability survey ...
The integrated properties of the CALIFA galaxies: model-derived galaxy parameters and quenching of star formation
(2019)
We present a study of the integrated properties of the 835 galaxies in the Calar-Alto Legacy Integral Field spectroscopy Area survey. To derive the main physical parameters of the galaxies we have fitted their UV-to-IR ...
