Supernova Burst and Diffuse Supernova Neutrino Background Simulator for Water Cherenkov Detectors

open access: yesThe Astrophysical Journal
If a Galactic core-collapse supernova explosion occurs in the future, it will be critical to rapidly alert the community to the direction of the supernova by utilizing neutrino signals in order to enable the initiation of follow-up optical observations ...

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 ...

Charged-Current Neutrino-Nucleus Scattering off the Even Molybdenum Isotopes

open access: yesAdvances in High Energy Physics, 2012
Neutrinos from supernovae constitute important probes of both the currently unknown supernova mechanisms and of neutrino properties. Reliable information about the nuclear responses to supernova neutrinos is therefore crucial.

The ν process in the innermost supernova ejecta

open access: yesEPJ Web of Conferences, 2017
The neutrino-induced nucleosynthesis (ν process) in supernova explosions of massive stars of solar metallicity with initial main sequence masses between 13 and 30 M⊙ has been studied with an analytic explosion model using a new extensive set of neutrino ...

Distances to Recent Near-Earth Supernovae from Geological and Lunar 60Fe

open access: yesThe Astrophysical Journal
Near-Earth supernova blasts which engulf the solar system have left traces of their ejecta in the geological and lunar records. There is now a wealth of data on live radioactive ^60 Fe pointing to a supernova at 3 Myr ago, as well as the recent discovery

Acceleration and Transport of the Unstable Cosmic-Ray Isotope 60Fe in Supernova-enriched Environments

open access: yesThe Astrophysical Journal
The unstable isotope ^60 Fe, with a half-life of 2.6 million years, is produced primarily in supernova explosions. The observed presence of ^60 Fe in cosmic rays and its detection in deep-sea crusts and sediments suggest two possible scenarios: either ...

LAMOST J1010+2358 is not a Pair-Instability Supernova Relic

open access: yesThe Open Journal of Astrophysics
The discovery of a star formed out of pair-instability supernova ejecta would have massive implications for the Population III star initial mass function and the existence of stars over 100 Msun, but none have yet been found.

Shedding light on the Δm212 tension with supernova neutrinos

open access: yesPhysics Letters B
One long-standing tension in the determination of neutrino parameters is the mismatched value of the solar mass square difference, Δm212, measured by different experiments: the reactor antineutrino experiment KamLAND finds a best fit larger than the one ...
