Newtonian boson spheres

Newtonian boson spheres The Newtonian limit of a boson star is analyzed as a function of the number of its component particles ( N ). For moderate N , the sphere is in the collisionless regime and its radius ( R ) satisfies the law R ∝ N - 1 m - 3 , m being the elementary boson mass. For increasing N , this dependence stops when the interparticle repulsion takes over in the equation of state and the cluster turns into an n = 1 polytrope: Thus R becomes constant, independent of N . The physical scales involved and some phenomenological implications are briefly discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review D American Physical Society (APS)

Abstract

The Newtonian limit of a boson star is analyzed as a function of the number of its component particles ( N ). For moderate N , the sphere is in the collisionless regime and its radius ( R ) satisfies the law R ∝ N - 1 m - 3 , m being the elementary boson mass. For increasing N , this dependence stops when the interparticle repulsion takes over in the equation of state and the cluster turns into an n = 1 polytrope: Thus R becomes constant, independent of N . The physical scales involved and some phenomenological implications are briefly discussed.
