Dark matter heat transport can erase convective cores in solar-mass stars, yielding asteroseismic constraints on dark matter-nucleon scattering and a 4 sigma hint of dark matter-electron scattering in KIC 8228742 that conflicts with direct detection limits.

abstract
Capt'n General is a FORTRAN90 standalone package that can be used to compute the capture and heat transport of dark matter in stars. It can compute capture rates for constant, velocity and momentum-dependent DM-nucleon elastic scattering cross sections, as well as non-relativistic effective operator interactions. Capt'n General can be interfaced with the GAMBIT global fitting codebase as well as stellar evolution simulation codes such as MESA.

Asteroseismological constraints on--and hints of--dark matter interactions
Dark matter heat transport can erase convective cores in solar-mass stars, yielding asteroseismic constraints on dark matter-nucleon scattering and a 4 sigma hint of dark matter-electron scattering in KIC 8228742 that conflicts with direct detection limits.
