The gravitational collapse of a primordial cloud does differ of the gravitational collapse of normal interstellar clouds, mostly because radiative cooling processes and opacity are very different. Fragmentation is of course affected by this. In the seventies it was believed that fragmentation could be inhibited below one or several solar masses in a zero-metal environment, leading to a first stellar generation with no low-mass stars. However the problem appears more complex now, and recent work on the subject, both theoretical and observational, are surveyed.gravitational collapsepopulation IIIprimordial matter
