Abstract
The Newtonian limit of a boson star is analyzed as a function of the number of its component particles (). For moderate , the sphere is in the collisionless regime and its radius () satisfies the law , being the elementary boson mass. For increasing , this dependence stops when the interparticle repulsion takes over in the equation of state and the cluster turns into an polytrope: Thus becomes constant, independent of . The physical scales involved and some phenomenological implications are briefly discussed.
