Abstract:
Evolution of inhomogeneities in the axion field around the QCD epoch is studied numerically, including for the first time important non-linear effects. It is found that perturbations on scales corresponding to causally disconnected regions at can lead to very dense axion clumps, with present density \rho_a \ga 10~{-8}\,{\rm g \, cm~{-3}}. This is high enough for the collisional process to lead to Bose--Einstein relaxation in the gravitationally bound clumps of axions, forming Bose stars.- astrophysics
