We investigate the stability of general-relativistic boson stars by classifying singularities of differential mappings and compare it with the results of perturbation theory. Depending on the particle number, the star has the following regimes of behavior: stable, metastable, pulsation, and collapse.

  1. Boson Stars in $D \ge 4$ Dimensions: Stability, Oscillation Frequencies, and Dynamical Evolutions

    gr-qc 2025-10 conditional novelty 9.0 of 10

    Self-interacting boson stars in D=5,6 and solitonic boson stars in D=5 can be radially stable, as shown by generalized pulsation equations and nonlinear spherical evolutions.

  2. Radial spectra and dynamical signatures of excited boson stars

    gr-qc 2026-08 conditional novelty 6.0 of 10

    For excited boson stars, the first zero of the fundamental radial mode matches the first critical point of mass, charge, and binding energy for all tested node numbers and self-interactions.
