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 1S2S^1S^2S and 1S2P^1S^2P states. We show the mass MM of SIMBSs as a function of the synchronized frequency ω\omega, and the nonsynchronized frequency ω2\omega_2 for three different cases. Moreover, for the case of two coexisting states with self-interacting potential, we study the mass MM of SIMBSs versus the angular momentum JJ for the synchronized frequency ω\omega and the nonsynchronized frequency ω2\omega_2. 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 Λ\Lambda, and find the coupling parameter Λ\Lambda exists the finite range.
