Amplification of turbulence in contracting prestellar cores in primordial minihalos
Sho Higashi, Hajime Susa, Gen Chiaki
We investigate the amplification of turbulence through gravitational contraction of the primordial gas in minihalos. We perform numerical simulations to follow the cloud collapse,…
Formation of massive stars under protostellar radiation feedback: Very metal-poor stars
Hajime Fukushima, Takashi Hosokawa, Gen Chiaki +3
We study the formation of very metal-poor stars under protostellar radiative feedback effect. We use cosmological simulations to identify low-mass dark matter halos and star-formin…
Particle splitting in smoothed particle hydrodynamics based on Voronoi diagram
Gen Chiaki, Naoki Yoshida
We present a novel method for particle splitting in smoothed particle hydrodynamics simulations. Our method utilizes the Voronoi diagram for a given particle set to determine the p…
Growth of dust grains in a low-metallicity gas and its effect on the cloud fragmentation
Gen Chiaki, Takaya Nozawa, Naoki Yoshida
In a low-metallicity gas, rapid cooling by dust thermal emission is considered to induce cloud fragmentation and play a vital role in the formation of low-mass stars (<~ 1 M_sun) i…
