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 authors integrate metallicity‑dependent massive‑star explodability prescriptions into galactic chemical evolution models, showing they reproduce observed elemental abundances a…

Neural-Network Chemical Emulator for First-Star Formation: Robust Iterative Predictions over a Wide Density Range
Sojun Ono, Kazuyuki Sugimura
We present a neural-network emulator for the thermal and chemical evolution in Population III star formation. The emulator accurately reproduces the thermochemical evolution over a…
