WLM-1: A Non-Rotating, Gravitationally Unperturbed, Highly Elliptical Extragalactic Globular Cluster
Andrew W. Stephens, Marcio Catelan, Roxana P. Contreras
Globular clusters have long been known for presenting (at times) significant deviations from spherical symmetry. While rotation has been the main proposed explanation, other compli…
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…
Homogeneous Photometry V: The Globular Cluster NGC 4147
P. B. Stetson, M. Catelan, H. A. Smith
New BVRI broad-band photometry and astrometry are presented for the globular cluster NGC 4147, based upon measurements derived from 524 ground-based CCD images mostly either donate…
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…
Horizontal Branch Stars: The Interplay between Observations and Theory, and Insights into the Formation of the Galaxy
M. Catelan
We review HB stars in a broad astrophysical context, including both variable and non-variable stars. A reassessment of the Oosterhoff dichotomy is presented, which provides unprece…
