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

TL;DR

This study uses asteroseismic modeling of the star KIC 2009504 to investigate how certain dark-matter particle models could affect stellar structure, providing constraints on dark matter properties.

Contribution

It demonstrates that the presence of a convective core in KIC 2009504 can rule out specific dark-matter particle models based on asteroseismic data.

Findings

Presence of a convective core excludes some dark-matter models.

Asteroseismology constrains dark-matter particle properties.

Results challenge certain dark-matter explanations from direct detection.

Abstract

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.
