Gravitational stability and fragmentation condition for discs around accreting supermassive stars
Ryoki Matsukoba, Sanemichi Z. Takahashi, Kazuyuki Sugimura +1
Supermassive stars (SMSs) with mass are promising candidates for the origin of supermassive black holes observed at redshift . They are suppos…
Super-Eddington accretion of dusty gas onto seed black holes: metallicity-dependent efficiency of mass growth
Daisuke Toyouchi, Takashi Hosokawa, Kazuyuki Sugimura +2
The super-Eddington accretion onto intermediate seed BHs is a potential formation mode of supermassive black holes exceeding in the early universe. We here investiga…
Stunted accretion growth of black holes by combined effect of the flow angular momentum and radiation feedback
Kazuyuki Sugimura, Takashi Hosokawa, Hidenobu Yajima +2
Accretion on to seed black holes (BHs) is believed to play a crucial role in formation of supermassive BHs observed at high-redshift (z>6). Here, we investigate the combined effect…
