We study energy transport by asymmetric dark matter in the interiors of verylow-mass stars and brown dwarfs. Our motivation is to explore astrophysicalsignatures of asymmetric dark matter, which otherwise may not be amenable toconventional indirect dark matter searches. In viable models, the additionalcooling of very-low mass stellar cores can alter stellar properties. Asymmetricdark matter with mass 4 < Mx/GeV < 10 and a spin-dependent (spin-independent)cross sections of sigma \sim 10^{-37} cm^2 (sigma \sim 10^{-40} cm^2) canincrease the minimum mass of main sequence hydrogen burning, partly determiningwhether or not the object is a star at all. Similar dark matter candidatesreduce the luminosities of low-mass stars and accelerate the cooling of browndwarfs. Such light dark matter is of particular interest given results from theDAMA, CoGeNT, and CRESST dark matter searches. We discuss possibilities forobserving dark matter effects in stars in the solar neighborhood, globularclusters, and, of particular promise, local dwarf galaxies, among otherenvironments, as well as exploiting these effects to constrain dark matterproperties.

Asymmetric Dark Matter May Alter the Evolution of Low-mass Stars and Brown Dwarfs
