Asteroseismic constraints on Asymmetric Dark Matter: Light particles with an effective spin-dependent coupling

Understand

So far, direct detection searches have come empty handed in their quest for Dark Matter (DM).

• Meanwhile, asteroseismology arises as a complementary tool to study DM, as its accumulation in a star can enhance energy transport, by providing a conduction mechanism, producing significant changes in the stellar structure during the course of the star's evolution.
• The stellar core, particularly affected by the presence of DM, can be investigated through precise asteroseismic diagnostics.
• We modelled three stars including DM energy transport: the Sun, a slightly less massive and much older star, KIC 7871531 ($0.85 \, M_{\odot}$, $9.41 \, \text{Gyr}$), and a more massive and younger one, KIC 8379927 ($1.12 \, M_{\odot}$, $1.82 \, \text{Gyr}$).
