  We study the effects of feebly or non-annihilating weakly interacting Dark
Matter (DM) particles on stars that live in DM environments denser than that of
our Sun. We find that the energy transport mechanism induced by DM particles
can produce unusual conditions in the core of Main Sequence stars, with effects
which can potentially be used to probe DM properties. We find that solar mass
stars placed in DM densities of rhochi>= e2 GeV/cm3 are sensitive to
Spin-Dependent scattering cross-section sigmsd >= e-37 cm2 and a DM particle
mass as low as mchi=5 GeV, accessing a parameter range weakly constrained by
current direct detection experiments.
