Cell-based theoretical criteria on the onset and stability limit of thermonuclear detonation
Kazuya Iwata, Keiichi Maeda, Ken J. Shen
One of the key unresolved problems in thermonuclear explosions of white dwarfs (WDs), including type Ia supernovae, is the condition for ignition and propagation of thermonuclear f…
Constraints on the Metallicity-dependent Explodability of Massive Stars from Galactic Chemical Evolution: Toward Alleviating the Red Supergiant Problem
Sojun Ono, Keiichi Maeda, Akihiro Suzuki
The explodability of massive stars, namely whether they undergo core-collapse supernovae (CCSNe) or form black holes (BHs), strongly influences galactic chemical evolution (GCE). D…
Cellular Dynamics of Helium-rich Detonation on sub-Chandrasekhar Mass White Dwarf
Kazuya Iwata, Keiichi Maeda
Most previous efforts for hydrodynamic studies on detonation in the context of Type Ia supernovae did not take into account the scale of the cellular structure for a criterion in i…
Viewing explosion models of type Ia supernovae via the insight from terrestrial cellular detonation
Kazuya Iwata, Keiichi Maeda
The cellular structure is considered to be a key as a criterion in initiation, propagation, and quenching of terrestrial detonation. While a few studies on type Ia supernovae, whic…
