摘要：
Boson stars built from a very light Kalb-Ramond axion, the dilaton or other moduli fields of effective string models could provide a considerable fraction of the non-baryonic part of dark matter. Gravitational microlensing of similar to0.5 M-circle dot MACHOs within the halo of galaxies may indirectly "weighing" the mass of the constituent scalar particle, resulting in similar to 10(-10) eV/c(2).
