The first stars to light the early universe may have been powered by dark matter, according to a new study. Researchers from the University of Michagan, Ann Arbor call these very first stars "Dark Stars," and propose that dark matter heating provided the energy for these stars instead of fusion. The researchers [...]

Due to the density available for star formation in the early universe, I would expect the protostellar clouds of the era to have tended to be too massive with just the hadronic matter. The problem would have been generating so much heat from compressing the hadronic matter that, in conjunction with increased spin from the conservation of angular momentum, would have prevented the cloud from evolving into a star.
