  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 WIMP-influenced stellar models for main sequence
stars, computed using the DarkStars code. We describe the changes in stellar
structure and main sequence evolution which occur for masses ranging from 0.3
to 2.0 solar masses and metallicities from Z = 0.0003-0.02, as a function of
the rate of energy injection by WIMPs. We then go on to show what rates of
energy injection can be obtained using realistic orbital parameters for stars
near supermassive black holes, including detailed considerations of dark matter
halo velocity and density profiles. Capture and annihilation rates are strongly
boosted when stars follow elliptical rather than circular orbits, causing WIMP
annihilation to provide up to 100 times the energy of hydrogen fusion in stars
at the Galactic centre.
