International Astronomical Union Colloquium, 2005 SummaryIn this paper are summarized the main advances of the last years in the field of SN spectra . The arguments against a monodimensional sequence for SNIa are discussed as well as the efforts to improve the temporal and spectral coverage of this kind of SNe, with the aim to understand the physics of the explosions for their use as cosmological ...

Superluminous Supernovae [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractNot long ago the sample of well studied supernovae, which were gathered mostly through targeted surveys, was populated exclusively by events with absolute peak magnitudes fainter than about −20. Modern searches that select supernovae not just from massive hosts but from dwarfs as well have produced a new census with a surprising difference: a ...

Science, 2007 Analysis of the polarization of light from supernovae can reveal the shape and distribution of matter ejected from exploding stars. Here we review the young field of Type Ia supernova spectropolarimetry and critically evaluate, and place in context, the recent work of Wang et al.

Gamma-ray emission from young supernova remnants: Hadronic or leptonic?
EPJ Web of Conferences, 2016 The debate on the nature of the gamma-ray emission from young supernova remnants is still open. Ascribing such emission to hadronic rather than leptonic processes would provide an evidence for the acceleration of protons and nuclei, and this fact would ...

Supernova theory and supernova 1987A
The Astrophysical Journal, 1987 The implications of Supernova 1987A are examined and compared with theoretical expectations. The relatively low luminosity follows from the progenitor having lower than solar abundances. The explosion energy is (1.0-2.0) x 10 to the 51st ergs for a 15 solar mass star.

Supernova 1604, Kepler’s Supernova, and Its Remnant [PDF]
, 2016 Supernova 1604 is the last Galactic supernova for which historical records exist. Johannes Kepler's name is attached to it, as he published a detailed account of the observations made by himself and European colleagues. Supernova 1604 was very likely a Type Ia supernova, which exploded 350 pc to 750 pc above the Galactic plane.
