New insights into the formation and growth of boson stars in dark matter
  halos
  This work studies the formation and growth of boson stars and their
surrounding miniclusters by gravitational condensation using non-linear
dynamical numerical methods. Fully dynamical attractive and repulsive
self-interactions are also considered for the first time. In the case of pure
gravity, we numerically prove that the growth of boson stars inside halos slows
down and saturates as has been previously conjectured, and detail its
conditions. Self-interactions are included using the Gross-Pitaevskii-Poisson
equations. We find that in the case of strong attractive self-interactions the
boson stars can become unstable and collapse, in agreement with previous
stationary computations. At even stronger coupling, the condensate fragments.
Repulsive self-interactions, as expected, promote boson star formation, and
lead to solutions with larger radii.
