Supernova theory and supernova 1987A

open access: yesThe 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.

Gamma-ray emission from young supernova remnants: Hadronic or leptonic?

open access: yesEPJ 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 ...

Performance of SK-Gd’s Upgraded Real-time Supernova Monitoring System

open access: yesThe Astrophysical Journal
Among multimessenger observations of the next Galactic core-collapse supernova, Super-Kamiokande (SK) plays a critical role in detecting the emitted supernova neutrinos, determining the direction to the supernova (SN), and notifying the astronomical ...
