No-go theorem for static boson stars
arXiv:1902.05230 · doi:10.1016/j.physletb.2018.01.036
Abstract
It is proved that self-gravitating static scalar fields whose self-interaction potential is a monotonically increasing function of its argument cannot form spherically symmetric asymptotically flat bound matter configurations. Our compact theorem rules out, in particular, the existence of spatially regular static boson stars made of nonlinear massive scalar fields.
