Scientific paper

Using thee-dimensional radiation hydrodynamics (RHD) simulations, we explore the radiative feedback effects by a Population III (Pop III) star on second star formation. We find that the adjacent peak can survive, although a shock associated with ionization front strips a large amount of gas. The surviving cloud is never ionized, but H2 fractions become large due to radiation hydrodynamic effects. These effects lower mass accretion rates onto the adjacent peak, and consequently the second star is likely to be less massive.
