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…

Angular momentum transport in the convection zone of a 3D MHD simulation of a rapidly rotating core-collapse progenitor

Ryota Shimada, Lucy O. McNeill, Vishnu Varma +3

Rotation and magnetic fields in the cores of evolved massive stars in their final phase are thought to play an important role in the subsequent supernova explosion and the formatio…

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…
