"Dark Stars: a new phase of stellar evolution driven by dark matter annihilation in the first stars"

Abstract. The first phase of stellar evolution in the history of the universe may be Dark Stars, powered by dark matter rather than by fusion. Weakly interacting massive particles, which are their own antiparticles, can annihilate and provide an important heat source for the first stars in the the universe. Hence these first stars may be powered by dark matter annihilation for an extended period of time en route to becoming fusion driven stars. This talk presents the story of these Dark Stars.
