Supernovae of Type II occur at the end of the evolution of massive stars. The phenomenon
begins when the iron core of the star exceeds a Chandrasekhar mass. The collapse of that …

Rapid progress has been made during recent years in the understanding of the flavour
oscillations that occur as neutrinos traverse through supernova. The previous paradigm has …

Supernova remnants are beautiful astronomical objects that are also of high scientific
interest, because they provide insights into supernova explosion mechanisms, and because …

The role of neutrino heating and convective processes in the explosion mechanism of Type-
II supernovae is investigated by one-and two-dimensional hydrodynamical simulations of …

We report far-infrared and submillimeter observations of supernova 1987A, the star whose
explosion was observed on 23 February 1987 in the Large Magellanic Cloud, a galaxy …

Two-dimensional hydrodynamic calculations of SN 1987A (Arnett, Fryxell, and Muller 1989)
have been confirmed and extended. A systematic sequence of calculations, differing only in …

We outline the possible physical processes, associated timescales, and energetics that
could lead to the production of pulsars, jets, asymmetric supernovae, and weak γ-ray bursts …

The orbital observatory Spectrum-Roentgen-Gamma (SRG), equipped with the grazing-
incidence X-ray telescopes Mikhail Pavlinsky ART-XC and eROSITA, was launched by …

A type Ia supernova is thought to be a thermonuclear explosion of either a single carbon–
oxygen white dwarf or a pair of merging white dwarfs. The explosion fuses a large amount of …

The gamma-ray spectrometer (GRS) on NASA's Solar Maximum Mission satellite (SMM) has
observed a significant (> 5δ) net line flux at˜ 847 keV in the background-subtracted spectrum …
