The axion is a hypothetical particle postulated to solve the strong-CP problem in quantum chromodynamics and has a cosmological significance as a dark matter candidate. Solar axions should be produced copiously in the Sun's core via nuclear reactions and is predicted to convert to X-rays in a magnetic field perpendicular to its velocity vector. RHESSI has been used to search for the faint X-ray emission from axions converting in coronal magnetic fields (Hannah et al. 2007 ApJL). We plan on continuing this search, exploiting the unique spatial and spectral emission predicted for axions, using RHESSI and other X-ray data.
