On the newly discovered Canes Venatici II dSph galaxy
C. Greco, M. Dall'Ora, G. Clementini +11
We report on the detection of variable stars in the Canes Venatici II (CVn II) dwarf spheroidal galaxy, a new satellite of the Milky Way recently discovered by the Sloan Digital Sk…
Multimodal Horizontal Branches: Empirical Evidence and Possible Evolutionary Scenarios
M. Catelan
We review the available empirical evidence for the presence of "gaps" and multimodal distributions among horizontal branch (HB) stars, along with some of the theoretical scenarios…
Meet the COG's
Martin Altmann, Marcio Catelan, Manuela Zoccali
Kinematics combined with detailed element abundances provide the method of analysis of stellar populations using as much available information as possible, in contrast to other met…
Binaries among Extreme Horizontal Branch Stars in Globular Clusters
C. Moni Bidin, M. Catelan, S. Villanova +4
Following a review of our present knowledge about blue subdwarf stars in globular clusters, we present an overview of the results of searches for close binaries among these stars,…
A Search for EHB Pulsators in the Globular Cluster NGC 6752
M. Catelan, G. E. Prieto, M. Zoccali +8
We describe the status of a project whose main goal is to detect variability along the extreme horizontal branch of the globular cluster NGC 6752. Based on Magellan 6.5m data, prel…
Variable Stars in the Newly Discovered Milky Way Dwarf Spheroidal Satellite Canes Venatici I
Charles Kuehn, Karen Kinemuchi, Vincenzo Ripepi +11
We have identified 23 RR Lyrae stars and 3 possible Anomalous Cepheids among 84 candidate variables in the recently discovered Canes Venatici I dwarf spheroidal galaxy. The mean pe…
