Variable Stars in M13. III. The Cepheid Variables and their Relation to Evolutionary Changes in Metal-poor BL Her Stars
Wayne Osborn, Grzegorz Kopacki, Horace A. Smith +3
New CCD photometry has been combined with published and unpublished earlier observations to study the three Cepheid variables in M13: V1, V2 and V6. The light curve characteristics…
Variable Stars in Sagittarius Globular Clusters I. Arp~2
Barton J. Pritzl, Thomas C. Gehrman, Ricardo Salinas +3
We present new photometry and analysis of the twelve variable stars (nine RR Lyrae, three SX Phoenicis) belonging to the Sagittarius globular cluster Arp 2. Of the nine RR Lyrae st…
Chemical abundances in the globular clusters NGC 5024 and NGC 5466 from optical and infrared spectroscopy
Masen Lamb, Kim Venn, Matthew Shetrone +2
Detailed chemical abundances for five stars in two Galactic globular clusters, NGC 5466 and NGC 5024, are presented from high resolution optical (from the Hobby- Eberley Telescope)…
Exploring M33 Through RR Lyrae Stars
Barton J. Pritzl
Recent surveys have detected RR Lyrae stars in M33, the Triangulum Galaxy. These variable stars are excellent tracers of ancient stellar populations. The RR Lyrae stars have been u…
RR Lyrae in the LMC: Insights Into the Oosterhoff Phenomenon
Charles A Kuehn, Horace A. Smith, Marcio Catelan +8
Although more than eight decades have passed since P. Th. Oosterhoff drew attention to differences in the properties of RR Lyrae variables in globular clusters, the origin and sign…
Variable Stars in Large Magellanic Cloud Globular Clusters III: Reticulum
Charles A. Kuehn, Kyra Dame, Horace A. Smith +8
This is the third in a series of papers studying the variable stars in old globular clusters in the Large Magellanic Cloud. The primary goal of this series is to look at how the ch…
