Orbit-averaged DM energy exchange for S4714 reaches stellar luminosity at σ_χp ~ 10^{-36} cm² (MeV-GeV) and σ_χe ~ 5×10^{-38} cm² (sub-MeV) for spiked DM profiles.
Bayesian analysis finds that the likely ranges of light dark-matter fermion mass and exponential density-profile parameter in hyperon-containing neutron stars are nearly independent of the hadronic model for symmetry-energy slopes between 40 and 58 MeV, with HESS J1731-347 and GW170817 data playing,

Bayesian analysis of density profile of light dark matter elucidating the properties of dark matter admixed neutron stars in the presence of hyperons
