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…
