Description

The aim of the workshop is to dicuss the signals of gravitational waves and neutrinos  from core-collapse supernovae to probe into the stellar collapse and explosion as well as the birth of  compact objects.  The observational facilities such as Super-Kamiokande and KAGRA are prepared to detect the burst signals from the next supernova and the Super-Kamiokande with Gd loading will detect the first event of the diffuse supernova neutrino background.  The cutting-edge numerical simulations are revealing the explosion mechanism with prediction of signals and exploring variety of explosive phenomena .  We would like to exchange the latest understanding of observations and theories and to discuss how to extract the information from stellar core.

Topics to discuss

  • Gravitational waves and neutrinos from core-collapse supernovae
  • Observational aspects of gravitaional waves and neutrinos to extract the information
  • Numerical simulations of supernova explosions, the birth of compact objects
  • Influence of microphysics (equation of state, neutrino reactions) in core-collapse supernovae
  • Diffuse supernova neutrino background, neutrino oscillation of supernovae
