In this paper, we study gauged solutions associated to a massive vector field representing a spin-one condensate, namely the Proca field. We focus on regular spherically-symmetric solutions which we construct either using a self-interaction potential or general relativity in order to glue the solutions together. We start generating non-gravitating solutions, so-called, Proca Q-balls and charged Proca Q-balls. Then, we turn-on backreaction on the metric, allowing gravity to hold together the Proca condensate, to study the so-called Proca stars, charged Proca stars, Proca Q-stars and charged Proca Q-stars.

  1. Extreme mass-ratio inspirals into Newtonian Proca stars

    gr-qc 2026-07 accept novelty 6.0 of 10

    For Newtonian Proca stars, a perturbing object on a circular orbit loses nearly the same energy in the vector ground state as in the scalar boson-star ground state (within ~20%), while the spherical excited Proca stat...

  2. Nonrelativistic Proca stars: Spherical stationary and multi-frequency states

    gr-qc 2024-12 conditional novelty 6.0 of 10

    Nonrelativistic Proca stars have a ground state with constant polarization (linear or circular depending on the sign of the spin-spin coupling), and a symmetry-enhanced sector with λs=0 contains a continuum of multi-f...

  3. Proca stars in excited states

    gr-qc 2024-11 conditional novelty 6.0 of 10

    Excited Proca stars are always unstable: under perturbations they collapse, disperse, or migrate to the ground state, with migration possible only for a narrow set of negative-binding-energy configurations.

  4. The continuum spectrum of nonrelativistic multi-frequency Proca stars

    gr-qc 2026-03 conditional novelty 5.5 of 10

    At fixed particle number, spherical multi-frequency Proca stars form continuous 1- and 2-parameter families interpolating between discrete stationary states, and a subset with a nodeless component is linearly stable.

  5. Boson Stars in Bumblebee Gravity and Their Gravitational Waveforms from Extreme-Mass-Ratio Inspirals

    gr-qc 2025-12 conditional novelty 5.0 of 10

    In bumblebee gravity, the Lorentz-violating parameter ℓ makes mini-boson stars more compact for positive ℓ and produces LISA-detectable, sustained EMRI waveforms for penetrating orbits.
