New insights into the formation and growth of boson stars in dark matter halos

Understand

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.
