In this paper, we construct a static spherical symmetric Bardeen-Dirac Stars (BDSs) in the four-dimensional Anti-de Sitter (AdS) spacetime, which consists of the electromagnetic field and Dirac field coupled to gravity. We investigate the ADM mass, Noether charge and light rings of BDSs in AdS spacetime. In asymptotically Minkowski spacetime, the maximum frequency of BDSs is one. However, we observe that the maximum frequency of BDSs increases as the cosmological constant decreases in AdS spacetime. Additionally, BDSs can exhibit extreme behavior at low frequencies, refer to as Frozen Bardeen-Dirac stars (FBDSs) in AdS spacetime. FBDSs have a critical event horizon, where the metric function gtt is very close to zero. The matter is entirely encapsulated by this critical horizon, highly concentrated within it. When the magnetic charge is fixed, the FBDSs gradually disappear as the cosmological constant decreases.

  1. Dynamical Formation of Regular Black Holes

    gr-qc 2024-12 conditional novelty 7.0 of 10

    In quasi-topological gravity, a collapsing thin shell bounces at small radius, producing a regular, geodesically complete black hole instead of a singularity.

  2. Regular black holes from thin-shell collapse

    gr-qc 2024-12 conditional novelty 7.0 of 10

    In D≥5 pure gravity with an infinite tower of higher-curvature terms, spherical thin-shell collapse generically produces regular black holes that bounce into new universes.

  3. Scalarization of Bardeen spacetime

    gr-qc 2025-09 conditional novelty 5.0 of 10

    For scalarization of the full Bardeen spacetime, small magnetic charges give the usual smooth scalarization threshold, while large charges end in a 'frozen' horizonless scalarized state rather than a Bardeen black hole.

  4. Are regular black holes from pure gravity classified within the same thermodynamical topology?

    gr-qc 2024-12 conditional novelty 5.0 of 10

    Regular black holes from pure gravity share the same thermodynamic topology class W0+ with total winding number zero, under the single-temperature-zero assumption.

  5. Bardeen Spacetime with Charged Dirac Field

    gr-qc 2024-11 conditional novelty 4.0 of 10

    Charged Dirac stars in Bardeen spacetime have a magnetic-charge-dependent critical charge, and frozen star solutions form when the effective frequency omega - q c_c tends to zero.
