  Recent work has indicated that WIMP annihilation in stellar cores has the
potential to contribute significantly to a star's total energy production. We
report on progress in simulating the effects of WIMP capture and annihilation
upon stellar structure and evolution near supermassive black holes, using the
new DarkStars code. Preliminary results indicate that low-mass stars are the
most influenced by WIMP annihilation, which could have consequences for
upcoming observational programs.
