The soundtrack of RR Lyrae in Omega Cen at high-frequency
A. Calamida, S. K. Randall, M. Monelli +8
We present preliminary Sloan u',g'-band light curves for a sample of known RR Lyrae variables in the Galactic globular cluster Omega Cen. Results are based on the partial reduction…
Theoretical Modeling of the RR Lyrae Variables in NGC 1851
Andrea Kunder, Maurizio Salaris, Santi Cassisi +5
The RR Lyrae instability strip (IS) in NGC 1851 is investigated, and a model is presented which reproduces the pulsational properties of the RR Lyrae population. In our model, a st…
RR Lyrae Period-Amplitude Diagrams: From Bailey to Today
Horace A. Smith, Marcio Catelan, Charles Kuehn
More than a century ago, Solon Bailey's pioneering investigations of the variable stars in globular clusters allowed the first period-amplitude diagrams to be constructed for their…
New Variable Stars in CMa Globular Cluster Candidates
P. Amigo, M. Catelan, P. B. Stetson +3
We present the preliminary results of an image-subtraction analysis of the Galactic globular cluster M79 (NGC 1904), as well as a new investigation of the variable star population…
RR Lyrae Variables in NGC 2808
Andrea Kunder, Peter B. Stetson, Márcio Catelan +2
NGC 2808 is a unique globular cluster with not only a bimodal-horizontal branch (HB) but also with gaps on the blue horizontal branch. Adequate interpretation of the nature of the…
The Leo IV dwarf spheroidal galaxy: color-magnitude diagram and pulsating stars
M. I. Moretti, M. Dall'Ora, V. Ripepi +10
We present the first V, B-V color-magnitude diagram of the Leo IV dwarf spheroidal galaxy, a faint Milky Way satellite recently discovered by the Sloan Digital Sky Survey. We have…
