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…
Physical Conditions in Circumstellar Gas surrounding SN 1987A 12 Years After Outburst
Stephen P. Maran, George Sonneborn, Chun S. J. Pun +3
Two-dimensional spectra of Supernova 1987A were obtained on 1998 November 14-15 (4282 days after outburst) with the Space Telescope Imaging Spectrograph (STIS) on board the Hubble…
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…
Observations of the Crab Nebula and its pulsar in the far-ultraviolet and in the optical
Jesper Sollerman, Peter Lundqvist, Don Lindler +5
We present HST/STIS far-UV observations of the Crab nebula and its pulsar. Broad, blueshifted absorption arising in the nebula is seen in C IV 1550, reaching about 2500 km/s. This…
