Doc-summary/Abstract:
The formation and evolution of the Population III stars are examined on the assumption that primordial fluctuations had an isothermal component. It is proposed that immediately after recombination the scale of nonlinearity would be one-million to 100-million solar masses and clouds of this mass would separate from the comoving frame. Reasons are given why fragmentation is unlikely before centrifugal forces halt the collapse and a dense disk forms. According to the proposed scenario, most of the hidden mass could be in very low mass stars (which would have 'evaporated' from the tightly bound clusters of one-million to 100-million solar masses in which they formed), but a small percentage of the mass would be in very massive objects. Attention is given to cosmological implications of the model.
