Description
Strong deviations from the classical picture of stellar evolution are predicted when
low-mass stars are embedded in halos of dark matter (DM) particles with very high
densities, such as those expected in the inner parsec of our galaxy. In this talk we
will focus on two possible strategies to detect the influence of the DM captured
inside low-mass stars. First, by looking at the signatures of DM annihilation on the
stellar oscillations. Second, describing the impact on the appearance of a whole
stellar cluster, comparing the shape of the isochrones computed for a cluster within
a dense DM halo with those predicted for a classical stellar cluster.
