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

    gr-qc 2026-05 unverdicted novelty 6.0

    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.

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

    gr-qc 2026-05 unverdicted novelty 5.0

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

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

    gr-qc 2025-12 unverdicted novelty 5.0

    Numerical evolutions of quartically self-interacting boson stars reveal three merger outcomes and a non-monotonic gravitational-wave energy pattern driven by the competition between compactness and tidal deformability.

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

    gr-qc 2026-06 unverdicted novelty 4.0

    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...
