Abstract: Supermassive stars (SMSs) with $\sim10^{4-5}~\mathrm{M}_{\odot}$ are candidate objects for the origin of supermassive black holes observed at redshift $z$>6. They are supposed to form in primordial-gas clouds that provide the central stars with gas at… read more here.

Abstract: We study low-metallicity star formation with a set of high-resolution hydrodynamics simulations for various gas metallicities over a wide range 0–$10^{-3} \ {\rm Z_{\bigodot }}$. Our simulations follow non-equilibrium chemistry and radiative cooling by adopting… read more here.
