First asteroseismic limits on the nature of dark matter
  We report the first constraints on the properties of weakly interacting
low-mass dark matter (DM) particles using asteroseismology. The additional
energy transport mechanism due to accumulated asymmetric DM particles modifies
the central temperature and density of low-mass stars and suppresses the
convective core expected in 1.1-1.3 Ms stars even for an environmental DM
density as low as the expected in the solar neighborhood. An asteroseismic
modeling of the stars KIC 8006161, HD 52265 and Alpha Cen B revealed small
frequency separations significantly deviated from the observations, leading to
the exclusion of a region of the DM parameter space mass versus spin-dependent
DM-proton scattering cross section comparable with present experimental
constraints.
