Abstract:
The relaxation time of a gravitationally bounded cloud of bosons is estimated for the case of a large phase-space density of particles. The axionic mass and self-coupling relaxation time are compatible to the age of the Universe if the escape velocity and the mass in the core region satisfy the relation M < 108ve 5 2φ10 - 1 4M⊙. In the central part of such a cloud an axionic cosmic matter with luminosity ∼ 10-2vr 5 2φ10 - 1 4M⊙/yr will form. An upper bound on the self-coupling is obtained provided the mass distribution in galaxies is dominated by this kind of dark matter. © 1991.
