Chandra Observations of SNR 1987A
S. Park, D. N. Burrows, S. A. Zhekov +3
We report on the results of our monitoring program of the X-ray remnant of supernova 1987A with the {\it Chandra X-Ray Observatory}. We have performed two new observations during t…
Modelling the Hubble Space Telescope Ultraviolet and Optical Spectrum of Spot 1 on the Circumstellar Ring of SN 1987A
Chun S. J. Pun, Eli Michael, Svetozar A. Zhekov +18
We report and interpret HST/STIS long-slit observations of the optical and ultraviolet (1150 - 10270 Angstrom) emission-line spectra of the rapidly brightening Spot 1 on the equato…
The X-ray Spectrum of Supernova Remnant 1987A
Eli Michael, Svetozar Zhekov, Richard McCray +6
We discuss the X-ray emission observed from Supernova Remnant 1987A with the Chandra X-ray Observatory. We analyze a high resolution spectrum obtained in 1999 October with the high…
Monitoring the Evolution of the X-ray Remnant of SN 1987A
Sangwook Park, David N. Burrows, Gordon P. Garmire +4
We report on the results of our monitoring program of the remnant of SN 1987A with the Advanced CCD Imaging Spectrometer (ACIS) on board the {\it Chandra X-ray Observatory}. Two ne…
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…
