  text: Recent three-dimensional cosmological simulations of protogalaxy formation
    have suggested that supermassive stars (SMSs) can form in gas clouds in which
    H2 cooling is suppressed by dynamical heating prior to the activation of atomic
    cooling (Wise et al. 2019), but they stopped short of the following growth of
    a central protostar. Here we examine whether accretion on the protostellar core
    in this cloud is sufficiently rapid, in the face of the radiation feedback, to
    produce a SMS. We perform one-dimensional radiation-hydrodynamical simulations
    of the hot collapsing cloud with non-equilibrium chemical reactions directly adopting
    the cloud properties from Wise et al. (2019) as an initial condition. We find
    that the stellar Lyman-Werner (LW) radiation from the SMS dissociates H2 in the
    inner regions of the gas flow, increasing gas temperature and thermal pressure,
    and temporarily stopping the accretion. However, this negative feedback ceases
    when the self-gravity and inward ram pressure force on larger scales push the
    gas inward. The central protostar is unable to expand an HII region due to the
    high density, and grows to a mass of ≳105M⊙. Our results suggests the successful
    formation of SMSs, and resulting massive (∼105M⊙) remnant black holes in the clouds,
    but need to be confirmed in two- or three-dimensional simulations.
