The three dynamical fates of Boson Stars

Abstract

In this manuscript the three types of late-time behavior of spherically symmetric Boson Stars are presented, these are: stable configurations, unstable bounded that collapse to form black holes and unstable unbounded that explode. The results are found by solving the spherically symmetric Einstein-Klein-Gordon system of equations for a complex scalar field with initial conditions corresponding to a Boson Star. The solution is based on a constrained evolution that uses the method of lines for the scalar field and solves the constraint equations for the geometry on the fly.
