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 5-600 solar mass forming in the centre of a 1e6 solar mass halo at redhisft z=20. DM particles of the parent halo are accreted in the proto-stellar interior by adiabatic contraction and scattering/capture processes, reaching central densities of order 1e12… Expand

First star formation with dark matter annihilation
We include an energy term based on dark matter (DM) self-annihilation during the cooling and subsequent collapse of the metal-free gas, in haloes hosting the formation of the first stars in theExpand
WIMP DM and first stars: suppression of fragmentation in primordial star formation
We present the first 3D simulations to include the effects of dark matter annihilation feedback during the collapse of primordial mini-halos. We begin our simulations from cosmological initialExpand
Stellar Structure of Dark Stars: A First Phase of Stellar Evolution Resulting from Dark Matter Annihilation
Dark stars are the very first phase of stellar evolution in the history of the universe: the first stars to form (typically at redshifts -->z ~ 10–50) are powered by heating from dark matter (DM)Expand
DARK STARS: A NEW LOOK AT THE FIRST STARS IN THE UNIVERSE
We have proposed that the first phase of stellar evolution in the history of the Universe may be Dark Stars (DS), powered by dark matter heating rather than by nuclear fusion, and in this paper weExpand
THE FORMATION AND EVOLUTION OF YOUNG LOW-MASS STARS WITHIN HALOS WITH HIGH CONCENTRATION OF DARK MATTER PARTICLES
The formation and evolution of low-mass stars within dense halos of dark matter (DM) leads to evolution scenarios quite different from the classical stellar evolution. As a result of our detailedExpand
Impacts of WIMP dark matter upon stellar evolution: main-sequence stars
The presence of large amounts of WIMP dark matter in stellar cores has been shown to have significant effects upon models of stellar evolution. We present a series of detailed grids of WIMPinfluencedExpand
THE WIMP CAPTURE PROCESS FOR DARK STARS IN THE EARLY UNIVERSE
The first stars to form in the universe may have been dark stars, powered by dark matter annihilation instead of nuclear fusion. The initial amount of dark matter gathered by the star gravitationallyExpand
Dark stars at the Galactic Centre - the main sequence
In regions of very high dark matter density such as the Galactic centre, the capture and annihilation of WIMP dark matter by stars has the potential to significantly alter their evolution. WeExpand
Dark stars: a new study of the first stars in the Universe
We have proposed that the first phase of stellar evolution in the history of the Universe may be dark stars (DSs), powered by dark matter (DM) heating rather than by nuclear fusion. WeaklyExpand
SIGNATURES OF DARK MATTER BURNING IN NUCLEAR STAR CLUSTERS
In order to characterize how dark matter (DM) annihilation inside stars changes the aspect of a stellar cluster, we computed the evolution until the ignition of the He burning of stars from 0.7 M ?Expand
