Cluster AgeS Experiment: The Age and Distance of the Globular Cluster omega Centauri Determined from Observations of the Eclipsing Binary OGLEGC17
I. B. Thompson, J. Kaluzny, W. Pych +5
We use masses, radii, and luminosities of the detached eclipsing binary OGLEGC17 derived from photometric and spectroscopic observations to calculate the age and distance of the gl…
Analysis of the Type IIn Supernova 1998S: Effects of Circumstellar Interaction on Observed Spectra
Eric J. Lentz, E. Baron, Peter Lundqvist +20
We present spectral analysis of early observations of the Type IIn supernova 1998S using the general non-local thermodynamic equilibrium atmosphere code \tt PHOENIX}. We model both…
Preliminary Spectral Analysis of the Type II Supernova 1999em
E. Baron, David Branch, Peter H. Hauschildt +19
We have calculated fast direct spectral model fits to two early-time spectra of the Type-II plateau SN 1999em, using the SYNOW synthetic spectrum code. The first is an extremely ea…
The Dwarf Galaxy Population of the Dorado group down to Mv=-11
E. R. Carrasco, C. M. de Oliveira, Leopoldo Infante +1
We present V and I CCD photometry of suspected low-surface brightness dwarf galaxies detected in a survey covering ~2.4 deg^2 around the central region of the Dorado group of galax…
Variable Galaxies in the Hubble Deep Field
V. L. Sarajedini, R. L. Gilliland, M. M. Phillips
We present results from a study to detect variable galaxies in the Hubble Deep Field North. The goal of this project is to investigate the number density of AGN at z=1 through the…
HST Spectroscopy of Spot 1 on the Circumstellar Ring of SN 1987A
Eli Michael, Richard McCray, C. S. J. Pun +15
We present ultraviolet and optical spectra of the first bright spot (PA = 29 degrees) on Supernova 1987A's equatorial circumstellar ring taken with the Space Telescope Imaging Spec…
