We study the effects of WIMP dark matter (DM) on the collapse and evolution of the first stars in the Universe. Using a stellar evolution code, we follow the pre-Main Sequence (MS) phase of a grid of metal–free stars with masses in the range 5M⊙ ≤ M∗ ≤ 600M⊙ forming in the centre of a 10 6M⊙ halo at z = 20. DM particles of the parent halo are accreted in… CONTINUE READING
