摘要：
Light scalar fields can form gravitationally bound compact objects called boson stars. The profile of boson stars in the Newtonian limit is described by the Gross-Pitaevskii-Poisson equations. We present a semianalytic solution to these equations and construct the profile of boson stars formed by a noninteracting scalar field. Our solution is stable with respect to numerical errors and has accuracy better than 10-6 over the entire range.
