Sparse logistic regression for RR Lyrae vs binaries classification
Piero Trevisan, Mario Pasquato, Gaia Carenini +4
RR Lyrae (RRL) are old, low-mass radially pulsating variable stars in their core helium burning phase. They are popular stellar tracers and primary distance indicators, since they…
Multiple Stellar Populations in NGC 2808: a Case Study for Cluster Analysis
Mario Pasquato, Antonino Milone
In the massive globular cluster NGC 2808, RGB stars form at least five distinct groups in the so-called chromosome map photometric plane, arguably corresponding to different stella…
The extended halo of NGC 2682 (M 67) from Gaia DR2
R. Carrera, M. Pasquato, A. Vallenari +8
Context: NGC 2682 is a nearby open cluster, approximately 3.5 Gyr old. Dynamically, most open clusters should dissolve on shorter timescales, of ~ 1 Gyr. Having survived until now,…
Dynamical age differences among coeval star clusters as revealed by blue stragglers
F. R. Ferraro, B. Lanzoni, E. Dalessandro +11
Globular star clusters that formed at the same cosmic time may have evolved rather differently from a dynamical point of view (because that evolution depends on the internal enviro…
