Nucleosynthesis in the Accretion-induced Collapse of magnetised, Rotating White Dwarfs
Laurenz Thümmler, Takami Kuroda, Masaru Shibata
Accretion-induced collapse (AIC) of a rotating oxygen-neon-magnesium white dwarf (WD) is an alternative channel of neutron-star formation, in which a mass-accreting star near the C…
Exploring Physics beyond the Standard Model from kHz-Gravitational-Wave Signals of Core-Collapse Supernovae
Kei Kotake, Takami Kuroda
Recent advances in multidimensional modeling of core-collapse supernovae (CCSNe) have enabled detailed predictions of high-frequency gravitational-wave (GW) signals, offering a new…
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…
Collapse of Rotating White Dwarfs and Multimessenger Signals
Takami Kuroda, Kyohei Kawaguchi, Masaru Shibata
We present results of numerical relativity simulations for the collapse of rotating magnetized white dwarfs (WDs) in three dimension, aiming at discussing the explosion dynamics an…
