Our approach includes all the relevant atomic and molecular physics to follow the thermal evolution of a prestellar gas cloud to “stellar” densities. We describe the numerical implementation of the physics. We also show the result of a simulation of the formation of primordial stars in a reionized gas.}, pages = {18--23}, title = {Protostar formation in the early universe}, volume = {4}, year = {2008} }
