Self-interacting multistate boson stars
Abstract
In this paper, we consider rotating multistate boson stars with quartic self-interactions. In contrast to the nodeless quartic-boson stars in \cite{Herdeiro:2015tia}, the self-interacting multistate boson stars (SIMBSs) have two types of nodes, including the and states. We show the mass of SIMBSs as a function of the synchronized frequency , and the nonsynchronized frequency for three different cases. Moreover, for the case of two coexisting states with self-interacting potential, we study the mass of SIMBSs versus the angular momentum for the synchronized frequency and the nonsynchronized frequency . Furthermore, for three different cases, we analyze the coexisting phase with both the ground and first excited states for SIMBSs. We also calculate the maximum value of coupling parameter , and find the coupling parameter exists the finite range.
