The standard cosmological model predicts that first cosmological objects are formed when the age of the universe is a few hundred million years. Recent theoretical works and numerical simulations consistently suggests that the first objects are very massive primordial stars. We introduce the key physics and explain why the first stars are thought to be massive, rather than to be low-mass stars. The state-of-the-art simulation includes all the relevant atomic and molecular physics to follow the thermal evolution of a prestellar gas cloud to very high densities. We also show the result of a simulation of the formation of primordial stars in a reionized gas.
