Dilute and dense axion stars

Axion stars are hypothetical objects formed of axions, obtained as localized and coherently oscillating solutions to their classical equation of motion. Depending on the value of the field amplitude at the core |θ 0 |≡|θ(r=0)|, the equilibrium of the system arises from the balance of the kinetic pre...
