High-resolution radio imaging of young supernovae
M. A. Perez-Torres, J. M. Marcaide, A. Alberdi +12
The high resolution obtained through the use of VLBI gives an unique opportunity to directly observe the interaction of an expanding radio supernova with its surrounding medium. We…
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…
X-ray emission of young SN Ia remnants as a probe for an explosion model
D. I. Kosenko, E. I. Sorokina, S. I. Blinnikov +1
We present results of hydrodynamical simulations of young supernova remnants. To model the ejecta, we use several models (discussed in literature) of type Ia supernova explosions w…
Time-dependent thermal X-ray afterglows from GRBs
D. I. Kosenko, S. I. Blinnikov, K. A. Postnov +2
Time-dependent thermal X-ray spectra are calculated from physically plausible conditions around GRB. It is shown that account for time-dependent ionization processes strongly affec…
