Metals, dust and the cosmic microwave background: fragmentation of high-redshift star-forming clouds
Raffaella Schneider, Kazuyuki Omukai
We investigate the effects of the Cosmic Microwave Background (CMB) radiation field on the collapse of prestellar clouds. Using a semi-analytic model to follow the thermal evolutio…
Star Formation in Relic HII Regions of the First Stars: Binarity and Outflow Driving
Masahiro N. Machida, Kazuyuki Omukai, Tomoaki Matsumoto
Star formation in relic HII regions of the first stars is investigated using magneto-hydrodynamical simulations with a nested grid method that covers 10 orders of magnitude in spat…
Star Formation Triggered by Supernova Explosions in Young Galaxies
Takanori Nagakura, Takashi Hosokawa, Kazuyuki Omukai
We study the evolution of supernova remnants in a low-metallicity medium -- in the early universe, using one-dimensional hydrodynamics with non-eq…
Binary Formation with Different Metallicities: Dependence on Initial Conditions
Masahiro N. Machida, Kazuyuki Omukai, Tomoaki Matsumoto +1
The fragmentation process in collapsing clouds with various metallicities is studied using three-dimensional nested-grid hydrodynamics. Initial clouds are specified by three parame…
Low-Metallicity Protostars and the Maximum Stellar Mass Resulting from Radiative Feedback
Takashi Hosokawa, Kazuyuki Omukai
The final mass of a newborn star is set at the epoch when the mass accretion onto the star is terminated. We study the evolution of accreting protostars and the limits of accretion…
