How the first stars regulated the formation of later generations by their intense UV flux is key to the assembly of primeval galaxies, the rise of the first stellar populations, and the onset of cosmological reionization. It is commonly held that photoevaporation of cosmological halos by nearby Pop III stars quenched new star formation. We present a survey of halo photoevaporation by high-mass and low-mass primordial stars with simulations that self-consistently solve hydrodynamics, radiative transfer, and primordial gas chemistry. We find that ionizing and LW radiative feedback from a nearby star is much less destructive to star formation than is generally believed, and that it can even accelerate the collapse of baryons into new stars in some cases.
