We study head-on collisions of boson stars in three dimensions. We consider evolutions of two boson stars which may differ in their phase or have opposite frequencies but are otherwise identical. Our studies show that these phase differences result in different late time behavior and gravitational wave output.

  1. Establishing Compactness as a Population Observable in Gravitational-Wave Astronomy

    gr-qc 2026-06 unverdicted novelty 6.0 of 10

    Hierarchical analysis of GWTC-3 yields C_eff = 0.5^{+0.3}_{-0.1} consistent with black holes and limits low-compactness exotic binary merger rate to <0.7 Gpc^{-3} yr^{-1}.

  2. Compactness Inference in Gravitational-Wave Mergers with PhenomDECO: Catalog Benchmarks and Robustness Diagnostics

    gr-qc 2026-06 unverdicted novelty 6.0 of 10

    PhenomDECO analysis of GWTC-3 events finds all considered signals consistent with binary black holes once low-frequency noise effects are addressed via higher starting frequencies.

  3. 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.

  4. 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 ...

  5. 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...

  6. The three dynamical fates of Boson Stars

    gr-qc 2019-07 unverdicted novelty 3.0 of 10

    Numerical classification of spherically symmetric boson star evolutions into stable, black-hole-forming, and exploding categories via constrained evolution of the Einstein-Klein-Gordon system.
