SN 1994W: evidence of explosive mass ejection a few years before explosion
Nikolai N. Chugai, Robert J. Cumming, Sergei I. Blinnikov +7
We present and analyse spectra of the Type IIn supernova 1994W obtained between 18 and 202 days after explosion. During the first 100 days the line profiles are composed of three m…
High-resolution optical studies of nearby Type Ia supernovae
Peter Lundqvist, Seppo Mattila, Jesper Sollerman +5
Since April 2000, a program using the ESO/VLT/UVES to search for early circumstellar signatures from nearby supernovae has been conducted. Until now, two Type Ia supernovae have be…
The Iron Abundance and Density Structure of the Inner Ring around SN 1987A
S. Mattila, P. Lundqvist, P. Meikle +2
We present a spectroscopic study of the inner circumstellar ring around SN 1987A. The aim is to determine the elemental abundances and density structure, with particular emphasis o…
Pulsar optical observation with the Very Large Telescope
A. Ray, P. Lundqvist, J. Sollerman +2
Optical data in the V-band gathered with the 8.2m ESO Very Large Telescope (VLT) at the radio interferometric position of PSR 1706-44 are presented. The pulsar is close to a bright…
ISO SWS/LWS observations of SN 1987A
P. Lundqvist, J. Sollerman, C. Kozma +5
We report on observations of SN 1987A with ISO SWS/LWS made 9 - 11 years after the explosion. No emission from the supernova was seen. In particular, the upper limits on the fluxes…
Type II supernovae at high redshifts
Nikolai Chugai, Sergei Blinnikov, Peter Lundqvist
A hydro code coupled with radiation transfer was applied to produce monochromatic light curves of two models of type II supernovae (SN II) simulating SN II-P and SN IIb (SN 1993J-l…
