Influence of effective mass of the relativistic mean field theory on core collapse supernovae and compact objects

Kohsuke Sumiyoshi, Hajime Togashi, Shun Furusawa +4

We study the influence of the effective mass in the relativistic mean field (RMF) theory on the properties of the central core of collapse-driven supernovae and the formation of co…

Paleodetectors for neutrino signals from diverse Galactic stellar collapses

Mahiro Yamasaki, Ken'ichiro Nakazato

The paper studies how ancient minerals (paleodetectors) can record nuclear recoil tracks from neutrinos emitted by past Galactic core‑collapse supernovae, accounting for variations…

From supernovae to neutron stars: crust formation time

Yudai Suwa, Ken'ichiro Nakazato

A neutron star is born as a hot, lepton-rich protoneutron star (PNS) and cools via neutrino emission, eventually allowing heavy ions in the outer layers to crystallize into a solid…

Neutrino Constraints on Black Hole Formation in M31

Yudai Suwa, Ryuichiro Akaho, Yosuke Ashida +9

We investigate neutrino signals associated with black hole formation resulting from the gravitational collapse of massive stars, motivated by the candidate failed supernova M31-201…

Role of symmetry energy at subnuclear densities in protoneutron star crusts

Ken'ichiro Nakazato, Hajime Togashi, Kohsuke Sumiyoshi +1

The impact of matter properties at subnuclear densities on the evolution of protoneutron stars is investigated. Several models of nuclear equation of state (EOS) are constructed wi…

Observing Supernova Neutrino Light Curves with Super-Kamiokande.VI. A Practical Data Analysis Technique Considering Realistic Experimental Backgrounds

Fumi Nakanishi, Ken'ichiro Nakazato, Masayuki Harada +9

Neutrinos from supernovae, especially those emitted during the late phase of core collapse, are essential for understanding the final stages of massive star evolution. We have been…
