abstract

We study boson star configurations with generic, but not non-topological, self-interaction terms, i.e. we do not restrict ourselves just to consider the standard $\lambda |\psi|^4$ interaction but more general U(1)-symmetry-preserving profiles. We find that when compared with the usual potential, similar results for masses and number of particles appear. However, changes are of order of few percent of the star masses. We explore the stability properties of the configurations, that we analyze using catastrophe theory. We also study possible observational outputs: gravitational redshifts, rotation curves of accreted particles, and lensing phenomena, and compare with the usual case.

  1. Tidal Love numbers of multi-state Boson stars

    gr-qc 2026-07 conditional novelty 6.0 of 10

    Quadrupolar electric tidal Love numbers of multi-state boson stars flip from positive to negative when mu~1 > 0.891 or omega~0 > 0.777, while magnetic Love numbers stay negative.

  2. Timing-Window Mechanism for Chain-Like Transients in Collisions of Radially Excited Boson Stars

    gr-qc 2026-05 unverdicted novelty 6.0 of 10

    Chain-like transients in boson star collisions are governed by a timing window set by the binary collision time relative to isolated breathing clocks rather than excitation level alone.

  3. Massive boson stars: Stability and GW emission in head-on mergers

    gr-qc 2025-12 unverdicted novelty 6.0 of 10

    Quartically self-interacting massive boson stars are stable only up to the first mass maximum; their head-on mergers yield a boson-star remnant, a black hole at contact, or two black holes formed before contact, with ...

  4. Massive boson stars: Waveform-based branch diagnosis with neural reconstruction

    gr-qc 2026-06 unverdicted novelty 4.0 of 10

    Using an existing numerical-relativity catalogue, the paper builds a branch-conditioned neural reconstruction model that infers boson-star merger outcomes from waveform morphology by comparing reconstruction quality a...

  5. Hayward Boson Stars

    gr-qc 2025-08 conditional novelty 4.0 of 10

    Hayward boson stars exist only when sqrt(beta)/Q > 1.49661, exactly where the vacuum Hayward spacetime has no horizon.
