Query: The Effect of Dark Matter on the First Stars: A New Phase of Stellar
  Evolution   Dark matter (DM) in protostellar halos can dramatically alter the current
theoretical framework for the formation of the first stars. Heat from
supersymmetric DM annihilation can overwhelm any cooling mechanism,
consequently impeding the star formation process and possibly leading to a new
stellar phase. The first stars to form in the universe may be ``dark stars'';
i.e., giant (larger than 1 AU) hydrogen-helium stars powered by DM annihilation
instead of nuclear fusion. Possibilities for detecting dark stars are
discussed.
