An Explicit M1 Radiation-hydrodynamics Scheme for 3D Protostellar Evolution
Kazutaka Kimura, Kazuyuki Sugimura, Takashi Hosokawa +2
We present a radiation-hydrodynamics (RHD) scheme that enables 3D simulations resolving both protostellar interiors and their surrounding accretion flows within a single framework,…
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…
Unveiling the Ionized and Neutral ISM at z > 10 : The Origin of [O III] /[C II] Ratios from a Sub-parsec Resolution Radiative Transfer Simulation
Yurina Nakazato, Kazuyuki Sugimura, Akio K. Inoue +1
Recent multi-wavelength observations by JWST and ALMA are unveiling both ionized and neutral ISM components in high-redshift () galaxies. In this work, we investigate the orig…
Impact of Turbulent Magnetic Fields on Disk Formation and Fragmentation in First Star Formation
Kenji Eric Sadanari, Kazuyuki Omukai, Kazuyuki Sugimura +2
Recent cosmological hydrodynamic simulations have suggested that the first stars in the universe often form as binary or multiple systems. However, previous studies typically overl…
Gas Dynamical Friction on Accreting Objects
Tomoya Suzuguchi, Kazuyuki Sugimura, Takashi Hosokawa +1
The drag force experienced by astronomical objects moving through gaseous media (gas dynamical friction) plays a crucial role in their orbital evolution. Ostriker (1999) derived a…
