Instability analysis of massive static phantom wormholes via the spectral method by Davide Batic, Denys Dutykh

“…In the case of axial perturbations, the onset of instability occurs at smaller ratios, reflecting the impact of gravitational waves on the wormhole’s stability. The findings suggest that the wormhole remains stable when the throat size significantly exceeds the Schwarzschild radius. …”

A perturbative approach to complexity during shearing, dissipative collapse by Kevin Reddy, Megan Govender

“…The novelty of our work highlights the impact of pressure anisotropy and density inhomogeneity to the evolution of the complexity factor as a self-gravitating body evolves from an initially complexity-free and static regime into a dynamical radiating stellar object in the presence of shear.…”

Initial Parameter Analysis about Resonant Orbits in Earth-Moon System by Li-Bo Liu, Ying-Jing Qian, Xiao-Dong Yang

“…Based on an analysis of ballistic capture and flyby, the Kepler energy and the planet’s perturbed gravitational sphere are used as criteria to establish connections between the initial parameters and the possible “steady” resonant orbits. …”

The Quantization of a Kerr-AdS Black Hole by Claus Gerhardt

“…The stationary eigenfunctions can be interpreted as radiation and the temporal ones as gravitational waves. The event horizon corresponds in the quantum model to a Cauchy hypersurface that can be crossed by causal curves in both directions such that the information paradox does not occur. …”
