Effects of dark matter annihilation on the first stars
We study the evolution of the first stars in the universe (Population III) from the early pre–Main Sequence (MS) until the end of helium burning in the presence of WIMP dark matter annihilation inside the stellar structure. The two different mechanisms that can provide this energy source are the contemporary contraction of baryons and dark matter, and the capture of WIMPs by scattering off the ...
متن کاملDark matter annihilation effects on the first stars
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 the proto-stellar interior by adiabatic ...
متن کاملDark Matter Densities during the Formation of the First Stars and in Dark Stars
The first stars in the universe form inside ∼ 106M⊙ dark matter (DM) haloes whose initial density profiles are laid down by gravitational collapse in hierarchical structure formation scenarios. During the formation of the first stars in the universe, the baryonic infall compresses the dark matter further. The resultant dark matter density is presented here, using an algorithm originally develop...
متن کاملLight on Dark Matter
Galaxies are lighthouses that sit atop peaks in the density field. There is good observational evidence that these lighthouses do not provide a uniform description of the distribution of dark matter.
