The Zero Age Main Sequence of WIMP burners

Understand

We modify a stellar structure code to estimate the effect upon the main sequence of the accretion of weakly interacting dark matter onto stars and its subsequent annihilation.

• The effect upon the stars depends upon whether the energy generation rate from dark matter annihilation is large enough to shut off the nuclear burning in the star.
• Main sequence WIMP burners look much like protostars moving on the Hayashi track, although they are in principle completely stable.
• We make some brief comments about where such stars could be found, how they might be observed and more detailed simulations which are currently in progress.
