We study the time evolution of spherical, excited---with $n$ radial nodes---scalar boson stars in general relativity minimally coupled to a complex massive scalar field with quartic self-interactions. report that these stars, up $n=10$, can be made dynamically stable, timescales $t\ensuremath{\sim}\frac{1{0}^{4}}{c\ensuremath{\mu}}$, where $\ensuremath{\mu}$ is inverse Compton wavelength partic...
