An axion constraint from the diffuse supernova neutrino background indicated by Super-Kamiokande
Kanji Mori, Tomoya Takiwaki, Kazunori Kohri +1
Recently, the Super-Kamiokande Collaboration reported an indication of the diffuse supernova neutrino background (DSNB) with a statistical significance of . Motivated by this…
Circular polarization of gravitational waves from magnetorotational supernovae
Shota Shibagaki, Tomoya Takiwaki, Kei Kotake +2
Context. Gravitational waves (GWs) provide a unique probe of the explosion mechanism of massive stars and the evolution of nascent proto-neutron stars (PNSs). Magnetorotational exp…
Physical Conditions for Synthesis of Sc, Ti, and V in Neutrino-driven Supernovae
Ryota Hatami, Nozomu Tominaga, Takashi Yoshida +2
We present the results of simulations of nucleosynthesis in a core-collapse supernova (CCSN) including the neutrino process. Using the Si layer of zero-metal progenitor…
Modeling stellar convective transport with plumes : II. Transport Properties of Locally and Non-locally driven Convection
Youhei Masada, Tomoya Takiwaki, Nobumitsu Yoko
We perform three-dimensional hydrodynamic simulations of two idealized regimes of stellar convection: a cooling-driven model (Model C) and an entropy-gradient-driven model (Model S…
Verifying the failing supernova constraint on dark photons with two-dimensional hydrodynamic simulations
Kanji Mori, Tomoya Takiwaki, Kazunori Kohri
Recent studies on the dark photon (DP) production in collapsing stars argue that the cooling effect induced by DPs can hinder supernova explosions and lead to a ``failing supernova…
Effects of multidimensional treatment of gravity in simulations on supernova gravitational waves
Hajime Sotani, Bernhard Müller, Tomoya Takiwaki
Supernova explosions are expected as one of the promising candidates for gravitational wave sources. In this study, we examine the supernova gravitational waves, focusing on the mu…
