Discovery of 9,000 new RR Lyrae in the Southern Catalina Surveys
G. Torrealba, M. Catelan, A. J. Drake +8
We present the results of a deep, wide-area variability survey in the Southern hemisphere, the first of its kind. As part of the Catalina Sky Surveys, the Siding Spring Survey (SSS…
New galactic star clusters discovered in the VVV survey. Candidates projected on the inner disk and bulge
J. Borissova, A. -N. Chené, S. Ramírez Alegría +21
VISTA Variables in the Vía Láctea (VVV) is one of six ESO Public Surveys using the 4 meter Visible and Infrared Survey Telescope for Astronomy (VISTA). The VVV survey covers the Mi…
Constraints on Helium Enhancement in the Globular Cluster M4 (NGC 6121): The Horizontal Branch Test
A. A. R. Valcarce, M. Catelan, J. Alonso-García +2
Recent pieces of evidence have revealed that most, and possibly all, globular star clusters are composed of groups of stars that formed in multiple episodes with different chemical…
A New Lower Main Sequence Eclipsing Binary with Detached Components
M. Rozyczka, J. Kaluzny, P. Pietrukowicz +4
We present an analysis of NGC2204-S892 -- a new detached eclipsing binary composed of two late K dwarfs. Based on three photometric campaigns launched in 2008 we obtained 5 light c…
Constraints on Helium Enhancement in the Globular Cluster M3 (NGC 5272): The Horizontal Branch Test
M. Catelan, F. Grundahl, A. V. Sweigart +2
It has recently been suggested that the presence of multiple populations showing various amounts of helium enhancement is the rule, rather than the exception, among globular star c…
Evidence for an Overluminosity of the Variable Star RR Lyr, and a Revised Distance to the LMC
M. Catelan, C. Cortés
We use theoretical models to establish a tight relationship for the absolute magnitudes of RR Lyrae stars as a function of their periods and Stroemgren pseudo-color c_0 = (u-v)_0 -…
