The existence of dark matter in the solar neighbourhood can be tested in the framework of stellar evolution theory by using the new results of helioseismology and solar neutrinos. If weakly interacting massive particles accumulate in the centre of the Sun, they can provide an additional mechanism for transferring energy from the solar core to the outer regions. The presence of these particles produces a change in the local luminosity of the Sun of the same order of magnitude or larger that the difference between the Sun model's and the seismic data. In this paper I briefly present the difficulties in modelling the Sun, and argue in favour of using seismic data and neutrino measurements to constrain the super-symmetric particles candidates to the non-baryonic component of dark matter. Moreover, I discuss about how future helioseismological experiments have the potential for exploring most, if not all, of the parameter space of the weakly interacting massive particles accessible to the current and planned direct experiments for dark matter detection.
