Protostar Formation in the Early Universe
Naoki Yoshida, Kazuyuki Omukai, Lars Hernquist
The nature of the first generation of stars in the Universe remains largely unknown. Observations imply the existence of massive primordial stars early in the history of the univer…
Formation of Massive Primordial Stars in a Reionized Gas
Naoki Yoshida, Kazuyuki Omukai, Lars Hernquist
We use cosmological hydrodynamic simulations with unprecedented resolution to study the formation of primordial stars in an ionized gas at high redshifts. Our approach includes all…
The First Jet in the Universe: Protostellar Jets from the First Stars
Masahiro N. Machida, Kazuyuki Omukai, Tomoaki Matsumoto +1
The protostellar jets driven by the formation of the first stars are studied by using MHD nested grid simulations. Starting from a slowly rotating spherical cloud of 5.1 times 10^4…
Fragmentation of star-forming clouds enriched with the first dust
Raffaella Schneider, Kazuyuki Omukai, Akio Inoue +1
The thermal and fragmentation properties of star-forming clouds have important consequences on the corresponding characteristic stellar mass. The initial composition of the gas wit…
Dust-cooling--induced Fragmentation of Low-metallicity Clouds
T. Tsuribe, K. Omukai
Dynamical collapse and fragmentation of low-metallicity cloud cores is studied using three-dimensional hydrodynamical calculations, with particular attention devoted whether the co…
