We obtain bounds on the stability of various self-gravitating astrophysical objects using a new measure of shape complexity known as configurational entropy. We apply the method to Newtonian polytropes, neutron stars with an Oppenheimer-Volkoff equation of state, and to self-gravitating configurations of complex scalar field (boson stars) with different self-couplings, showing that the critical stability region of these stellar configurations obtained from traditional perturbation methods correlates well with critical points of the configurational entropy with accuracy of a few percent or better.

  1. Multishell Dirac fermions in the Einstein-Dirac system

    gr-qc 2025-07 conditional novelty 6.0 of 10

    Multishell solutions of the spherically symmetric Einstein-Dirac system are constructed for 2, 6, 12, and 20 fermions.

  2. Cosmological comoving behavior of the configurational entropy

    gr-qc 2019-08 reject novelty 5.0 of 10

    The paper claims the configurational entropy of cosmic fluids scales as a^{-3} for radiation and a^{-3/2} for matter, but the radiation result conflicts with the scale invariance of a blackbody spectrum.

  3. Configurational entropy and instability of tachyonic braneworld

    hep-th 2019-08 conditional novelty 4.0 of 10

    In a tachyonic braneworld, configurational entropy has a minimum at a critical scale-factor rate for AdS or flat bulk, and the paper suggests this rate sets cosmic acceleration or inflation, though the physical link i...

  4. Dynamical Boson Stars

    gr-qc 2012-02 unverdicted novelty 2.0 of 10

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