Dark Stars: the Dark Phase of the First Stars in the Universe

Abstract:  The first stars in the universe form at the center of dark 
matter (DM) halos.  As baryons cool and collapse, DM adiabatically 
contracts.  If DM is a WIMP, then the first stars are powered by dark 
matter i.e. Dark stars are brighter, cooler, and much more massive than 
without DM heating. They can also change the reionization history of the 
universe, seed the formation of massive black holes and maybe observable 
with JWST.
