Constraints to dark-matter properties from asteroseismic analysis of KIC 2009504

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.
