  Asteroseismology can be used to constrain some properties of dark-matter (DM)
particles (Casanellas & Lopes, 2013). In this work, we performed an
asteroseismic modelling of the main-sequence solar-like pulsator KIC 2009505
(also known as Dushera) in order to test the existence of DM particles with the
characteristics that explain the recent results found in some of the DM direct
detection experiments. We found that the presence of a convective core in KIC
2009504 is incompatible with the existence of some particular models of DM
particles.
