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 radiated energy varying non-monotonically at strong coupling.

abstract
We consider compact boson stars that arise for a V-shaped scalar field potential. They represent a one parameter family of solutions of the scaled Einstein-signum-Gordon equations. We analyze the physical properties of these solutions and determine their domain of existence. Along their physically relevant branch emerging from the compact Q-ball solution, their mass increases with increasing radius. Empoying arguments from catastrophe theory we argue that this branch is stable, until the maximal value of the mass is reached. There the mass and size are on the order of magnitude of the Schwarzschild limit, and thus the spiralling respectively oscillating behaviour, well-known for compact stars, sets in.

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.
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 across candidate hypotheses.
Boson stars are particle-like solutions in general relativity that model dark matter, black hole mimickers, and binary systems.

Massive boson stars: Stability and GW emission in head-on mergers
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 radiated energy varying non-monotonically at strong coupling.
