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

Bo-Xuan Ge

Quartically self-interacting massive boson stars remain stable only up to the first maximum on their mass curve, and equal-mass head-on collisions produce one of three outcomes depending on compactness.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Head-on collisions of equal-mass stars yield three distinct outcomes -- boson star remnants, black hole formation at contact, and collapse of each star to a black hole prior to contact. The associated gravitational-wave energies reflect a competition between increasing compactness, which enhances the efficiency of gravitational-wave emission, and decreasing tidal deformability, which suppresses merger asymmetries.

C2weakest assumption

Stability changes only at the first maximum of the mass curve M(|φ_c|); configurations beyond it become highly compact and collapse under numerically induced perturbations.

C3one line summary

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.
