We present a generalization of the curative initial data construction derived for equal-mass compact binaries in Helfer {\it et al} (2019 Phys. Rev. D 99 044046; 2022 Class. Quantum Grav. 39 074001) to arbitrary mass ratios. We demonstrate how these improved initial data avoid substantial spurious artifacts in the collision dynamics of unequal-mass boson-star binaries in the same way as has previously been achieved with the simpler method restricted to the equal-mass case. We employ the improved initial data to explore in detail the impact of phase offsets in the coalescence of equal- and unequal-mass boson star binaries.

  1. 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 ...

  2. Scalar fields from nonlinear sigma models on black hole spacetimes

    gr-qc 2025-08 conditional novelty 6.0 of 10

    Numerical evolutions show positive-curvature SL(2,R) sigma-model scalars create denser clouds and earlier binary mergers, while negative-curvature O(3) scalars spread out and delay mergers.

  3. Head-on Collisions of Boson Stars with Bowen-York Type Initial Data

    gr-qc 2026-07 accept novelty 5.5 of 10

    Bowen-York-type initial data for boson stars yields head-on collision results consistent with prior work: BBS radiate more GW energy than BBH, while BHBS radiate less.
