The Globular Cluster NGC 5286. II. Variable Stars
M. Zorotovic, M. Catelan, H. A. Smith +18
We present the results of a search for variable stars in the globular cluster NGC 5286, which has recently been suggested to be associated with the Canis Major dwarf spheroidal gal…
The Variable Star Population of the Globular Cluster B514 in the Andromeda Galaxy
Gisella Clementini, Rodrigo Contreras, Luciana Federici +8
A rich harvest of RR Lyrae stars has been identified for the first time in B514, a metal-poor ([Fe/H] = 1.95 +/- 0.10 dex) globular cluster of the Andromeda galaxy (M31), based on…
The Masses of Population II White Dwarfs
Jason S. Kalirai, D. Saul Davis, Harvey B. Richer +4
Globular star clusters are among the first stellar populations to have formed in the Milky Way, and thus only a small sliver of their initial spectrum of stellar types are still bu…
Variable Stars in the Fornax dSph Galaxy. III. The Globular Cluster Fornax 5
Claudia Greco, Gisella Clementini, Marcio Catelan +8
We present a new study of the variable star population in globular cluster 5 of the Fornax dwarf spheroidal galaxy, based on B and V time series photometry obtained with the MagIC…
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…
