  Current problems with the solar model may be alleviated if a significant
amount of dark matter from the galactic halo is captured in the Sun. We discuss
the capture process in the case where the dark matter is a Dirac fermion and
the background halo consists of equal amounts of dark matter and anti-dark
matter. By considering the case where dark matter and anti-dark matter have
different cross sections on solar nuclei as well as the case where the capture
process is considered to be a Poisson process, we find that a significant
asymmetry between the captured dark particles and anti-particles is possible
even for an annihilation cross section in the range expected for thermal relic
dark matter. Since the captured number of particles are competitive with
asymmetric dark matter models in a large range of parameter space, one may
expect solar physics to be altered by the capture of Dirac dark matter. It is
thus possible that solutions to the solar composition problem may be searched
for in these type of models.
