Disentangling multiple stellar populations in globular clusters using the Strömgren system
J. Alonso-García, M. Catelan, P. Amigo +10
An increasing amount of spectroscopic and photometric evidence is showing that the stellar populations of globular clusters are not as simple as they have been considered for many…
Variable stars in the Globular Cluster NGC 2808
Andrea Kunder, Peter B. Stetson, Marcio Catelan +2
The first calibrated broadband BVI time-series photometry is presented for the variable stars in NGC 2808, with observations spanning a range of twenty-eight years. We have also re…
The Horizontal Branch of NGC 1851: Constraints from its RR Lyrae Variables
Andrea Kunder, Maurizio Salaris, Santi Cassisi +5
We use the pulsational properties of the RR Lyrae variables in the globular cluster NGC 1851 to obtain detailed constraints of the various sub-stellar populations present along its…
