Systematic motions in the Galactic plane found in the Hipparcos Catalogue using Herschel's Method
Carlos Abad, Katherine Vieira
Two motions in the galactic plane have been detected and characterized, based on the determination of a common systematic component in Hipparcos catalogue proper motions. The proce…
New Quasars Detected via Variability in the QUEST1 Survey
A. W. Rengstorf, S. L. Mufson, C. Abad +31
By observing the high galactic latitude equatorial sky in drift scan mode with the QUEST (QUasar Equatorial Survey Team) Phase 1 camera, multi-bandpass photometry on a large strip…
A Large Area CCD Camera for the Schmidt Telescope at the Venezuelan National Astronomical Observatory
C. Baltay, J. A. Snyder, P. Andrews +25
We have designed, constructed and put into operation a large area CCD camera that covers a large fraction of the image plane of the 1 meter Schmidt telescope at Llano del Hato in V…
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…
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…
