Episodic excursions of low-mass protostars on the Hertzsprung-Russell diagram
Vardan G. Elbakyan, Eduard I. Vorobyov, Christian Rab +4
Following our recent work devoted to the effect of accretion on the pre-main-sequence evolution of low-mass stars, we perform a detailed analysis of episodic excursions of low-mass…
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…
Titans of the Early Universe: The Prato Statement on the Origin of the First Supermassive Black Holes
Tyrone E. Woods, Bhaskar Agarwal, Volker Bromm +30
In recent years, the discovery of massive quasars at z~7 has provided a striking challenge to our understanding of the origin and growth of supermassive black holes in the early Un…
Evolution and Final Fates of Rapidly Accreting Supermassive Stars
Takashi Hosokawa
The formation of supermassive stars (SMSs) is a possible pathway to seed supermassive black holes in the early universe. This chapter summarizes recent theoretical efforts to under…
The Impact of Feedback in Massive Star Formation. II. Lower Star Formation Efficiency at Lower Metallicity
Kei E. I. Tanaka, Jonathan C. Tan, Yichen Zhang +1
We conduct a theoretical study of the formation of massive stars over a wide range of metallicities from 1e-5 to 1Zsun and evaluate the star formation efficiencies (SFEs) from pres…
Radiation hydrodynamics simulations of photoevaporation of protoplanetary disks II: Metallicity dependence of UV and X-ray photoevaporation
Riouhei Nakatani, Takashi Hosokawa, Naoki Yoshida +2
We perform a suite of radiation hydrodynamics simulations of photoevaporating disks with varying the metallicity in a wide range of $10^{-3} \, Z_\odot \leq Z \leq 10^{0.5} \, Z_\o…
