Phys. Rev. D 53, 2236–2239 (1996)Galactic halos as boson starsReceived 28 July 1995; published in the issue dated 15 February 1996 We investigate a boson star with a self-interacting scalar field as a model of galactic halos. The model has slightly increasing rotation curves and allows wider ranges of the mass (m) and coupling (λ) of the halo dark matter particle than the noninteracting model previously suggested. The two quantities are related by λ1/2(mp/m)2≳1050. © 1996 The American Physical Society. © 1996 The American Physical Society URL:
