2D solar modeling
P. Ventura, V. Penza, L. Li +3
Understanding the reasons of the cyclic variation of the total solar irradiance is one of the most challenging targets of modern astrophysics. These studies prove to be essential a…
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…
Inclusion of turbulence in solar modeling
L. H. Li, F. J. Robinson, P. Demarque +2
The general consensus is that in order to reproduce the observed solar p-mode oscillation frequencies, turbulence should be included in solar models. However, until now there has n…
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…
