We study the vacuum solutions of a gravity model where Lorentz symmetry is spontaneously broken once a vector field acquires a vacuum expectation value. Results are presented for the purely radial Lorentz symmetry breaking (LSB), radial/temporal LSB and axial/temporal LSB. The purely radial LSB result corresponds to new black hole solutions. When possible, Parametrized Post-Newtonian (PPN) parameters are computed and observational boundaries used to constrain the Lorentz symmetry breaking scale.

Signatures of Lorentz violation in bright ring for Sgr A* images by radiation ineffective accretion flows
For a rotating Lorentz-violating black hole, increasing the LV parameter shrinks and broadens Sgr A*'s image ring, and EHT data bound the parameter over a spin-dependent range.

Primordial black hole in Lorentz-violating theories: Insights from Bumblebee gravity
Bumblebee gravity enhances primordial black hole abundance through three mechanisms, but the model harbors a ghost instability and a tachyonic instability that make it cosmologically unviable.

Complex bumblebee model
A complex bumblebee model is formulated with gauge and longitudinal couplings; one-loop RG functions are derived and the leading-log effective potential indicates possible dynamical Lorentz violation.

Lorentz violating quadratic gravity
Bumblebee–quadratic gravity needs new Lorentz-violating counterterms at one loop, but the displayed computation has a gauge-parameter inconsistency and the classical Schwarzschild/de Sitter solutions are the robust part.

A no-go theorem in bumblebee vector-tensor cosmology
Bumblebee gravity with non-minimal couplings is healthy only under the degeneracy σ=-ξ/2, which fixes the potential and yields a stealth de Sitter solution with scalar sound speed squared ≈1/6.

Stationary scalar clouds around a rotating BTZ-like black hole in the Einstein-bumblebee gravity
Fundamental stationary scalar clouds exist around rotating BTZ-like black holes in Einstein-bumblebee gravity, with the Lorentz-breaking parameter and angular quantum number having opposite effects and sometimes produ...

Nonrelativistic effective potential of the bumblebee model
The leading-order nonrelativistic potential in the bumblebee model is a Coulomb potential with charge rescaled by (1 - (mβξ/2)^2), producing a hydrogen level shift of order m^3β^2ξ^2.

Exact Black Hole Solutions in Bumblebee Gravity with Lightlike or Spacelike VEVS
New exact Schwarzschild-like, (A)dS-like, and charged black holes in bumblebee gravity with a two-component vector VEV keep Lorentz-violating corrections even when the VEV is lightlike, with Wald and first-law entropi...

Stationary scalar clouds around a rotating Kalb-Ramond BTZ black hole
Stationary scalar clouds exist around rotating KR BTZ black holes at superradiant threshold ω=mΩ_H, with positive KR parameter allowing nonmonotonic existence lines under Robin boundaries.
