We study the formation of Population III objects (and stars) taking into account the expansion of the Universe and a series of physical processes relevant to the primordial plasma. In particular, a very important way to cool the first condensations in the Universe is with molecular hydrogen. The minimum mass of the Population III objects formed is ~ 104M⊙. We show also that stars of mass ≳ 50M⊙ can be formed from the fragmentation of Population III objects of mass ~ 106M⊙.
