Multi-oscillating Boson Stars
arXiv:1904.02168 · doi:10.1103/PhysRevLett.123.131101
Abstract
We propose that stable boson stars generically fall within an infinite-parameter family of solutions that oscillate on any number of non-commensurate frequencies. We numerically construct two-frequency solutions and explore their parameter space. These solutions merge with the standard boson star family in the limit where the non-dominating frequencies are turned off. We find that for a fixed energy, these two-frequency solutions can differ considerably in size from standard boson stars.
