Description

We investigate the stability of oscillatons with a quartic self-interaction. Oscillatons are spherically symmetric solutions of the coupled Einstein-Klein-Gordon for the case of a real scalar field. It is shown that there exist equilibrium configurations which are stables under small and strong (radial) perturbations. Some basic numerical tools are implemented that shall help in the study of arbitrary equilibrium configurations.
