Abstract
We review our recent work on gravitationally bound condensates formed by Hermitian bosons interacting with a potential energy Λ4[1 − cos(A/f)]. We have used an expansion method to simplify the equations of motion. The expansion parameters are the binding energy of the condensed bosons, and the ratio between the scale of the Bose field f and the Planck mass. Applying our analysis to QCD axions, we find that the condensates have a limiting mass of O(1019) kg and a size of O(100) km.
