A bevy of light dark matter direct detection experiments have been proposed,
targeting spin-independent dark matter scattering. In order to be exhaustive,
non-standard signatures that have been investigated in the WIMP window
including spin-dependent dark matter scattering also need to be looked into in
the light dark matter parameter space. In this work, we promote this endeavor
by deriving indirect limits on sub-GeV spin-dependent dark matter through
terrestrial and astrophysical limits on the forces that mediate this
scattering.
