Completing the Census of (Bright) Variable Stars in Galactic Globular Clusters
M. Catelan, H. A. Smith, B. J. Pritzl +15
We present a long-term project aimed at completing the census of (bright) variable stars in Galactic globular clusters. While our main aim is to obtain a reliable assessment of the…
Newly Discovered Variable Stars in the Globular Clusters NGC 5634, Arp 2 and Terzan 8
R. Salinas, M. Catelan, H. A. Smith +2
We report the discovery of a sizeable, previously unknown variable star population in the Sagittarius dwarf spheroidal globular clusters NGC 5634, Arp 2 and Terzan 8. Location, pre…
RR Lyrae Variables in Globular Clusters and Nearby Galaxies
M. Catelan
I point out that the Oosterhoff dichotomy for globular cluster and field RR Lyrae (RRL) stars may place the strongest constraints so far on the number of dwarf spheroidal-like prot…
On the Oosterhoff Classification of the Unusual, Metal-Rich Globular Clusters NGC 6388 and NGC 6441
M. Catelan, A. V. Sweigart, B. J. Pritzl +1
We discuss the Oosterhoff classification of the unusual, metal-rich globular clusters NGC 6388 and NGC 6441, on the basis of new evolutionary models computed for a range of metalli…
Blue Horizontal--Branch Stars: The "Jump" in Stromgren u, Low Gravities, and Radiative Levitation of Metals
F. Grundahl, M. Catelan, W. B. Landsman +3
We study the ``jump'' in the blue horizontal--branch (BHB) distribution first detected by Grundahl et al. (1998) in the Galactic globular cluster (GC) M13. On the basis of Stromgre…
The Second-Parameter Effect in Metal-Rich Globular Clusters
Allen V. Sweigart
Recent Hubble Space Telescope (HST) observations by Rich et al. (1997) have shown that the metal-rich globular clusters (GCs) NGC 6388 and NGC 6441 exhibit a pronounced 2nd paramet…
