Internal Radiative Feedback Triggers Global Collapse and Direct-Collapse Black Hole Formation in Metal-free Atomic-Cooling Haloes
Masaki Kiyuna, Sunmyon Chon, Kazuyuki Omukai +1
The formation of heavy seed black holes from the collapse of supermassive stars (SMSs) is a promising pathway to the supermassive black holes (SMBHs). In the conventional direct-co…
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,…
Formation of supermassive stars and dense star clusters in metal-poor clouds exposed to strong FUV radiation
Sunmyon Chon, Kazuyuki Omukai
The direct collapse scenario, which predicts the formation of supermassive stars (SMSs) as precursors to supermassive black holes (SMBHs), has been explored primarily under the ass…
Impact of Ly radiation force on super-Eddington accretion onto a massive black hole
Takuya Mushano, Takumi Ogawa, Ken Ohsuga +2
The viability of super-Eddington accretion remains a topic of intense debate, crucial for understanding the formation of supermassive black holes in the early universe. However, th…
Gravitational collapse at low to moderate Mach numbers: The relationship between star formation efficiency and the fraction of mass in the massive object
Jorge Saavedra-Bastidas, Dominik R. G. Schleicher, Ralf S. Klessen +7
The formation of massive objects via gravitational collapse is relevant both for explaining the origin of the first supermassive black holes and in the context of massive star form…
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…
