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.

    In axisymmetric collapse of electromagnetic waves, the threshold of black hole formation shows approximate power-law scaling with exponent gamma ~ 0.145 and approximate echoing period Delta ~ 0.55, but the critical so...

  3. Critical phenomena in gravitational collapse with two competing massless matter fields

    gr-qc 2019-08 conditional novelty 7.0 of 10

    Near-critical collapse with a scalar field and a Yang-Mills field shows the scalar field dominating at small scales, explained by a conjectured quasi-periodically self-similar critical solution with one unstable mode.
