The determination of the age of Globular Clusters: a statistical approach
Miriam Rengel, Juan Mateu, Gustavo Bruzual
We present a statistical approach for determining the age of Globular Clusters (GCs) that allows estimating the age derived from CMDs more accurately than the conventional methods…
The QUEST RR Lyrae Survey: Confirmation of the Clump at 50 kpc and Other Over-Densities in the Outer Halo
A. K. Vivas, R. Zinn, P. Andrews +33
We have measured the periods and light curves of 148 RR Lyrae variables from V=13.5 to 19.7 from the first 100 sq. degrees of the QUEST RR Lyrae survey. Approximately 55% of these…
Discovery of the Bright Trans-Neptunian Object 2000 EB173
Ignacio Ferrin, D. Rabinowitz, B. Schaefer +45
We describe the discovery circumstances and photometric properties of 2000 EB173, now one of the brightest trans-Neptunian objects (TNOs) with opposition magnitude m_R=18.9 and als…
Vacuum effects in an asymptotically uniformly accelerated frame with a constant magnetic field
Victor M. Villalba, Juan Mateu
In the present article we solve the Dirac-Pauli and Klein Gordon equations in an asymptotically uniformly accelerated frame when a constant magnetic field is present. We compute, v…
Discovery of the Optical Transient of the Gamma Ray Burst 990308
Bradley E. Schaefer, J. A. Snyder, J. Hernandez +53
The optical transient of the faint Gamma Ray Burst 990308 was detected by the QUEST camera on the Venezuelan 1-m Schmidt telescope starting 3.28 hours after the burst. Our photomet…
