Description
The gravitational instability of free and dilute Newtonian boson clouds
has been examined. For collisionless Newtonian boson clouds with a
uniform unperturbated Bose gas density, it is deduced that the
gravitational instability will never give rise to the formation of boson
stars, but only black holes; however if the unperturbated density, in
the neighbourhood of the perturbation, has a scale length equal to or
smaller than the perturbation wavelength, the formation of free
Newtonian boson stars could also be possible. For dilute Newtonian boson
clouds it is shown that the gravitational instability can lead the cloud
to condense into boson stars of different masses but identical radii, in
agreement with studies about equilibrium configurations of dilute
Newtonian boson stars. The galactic distribution of these Newtonian
boson stars, and hence, the average distance among them is also
discussed.
