Sources of matter for wormholes in a k-essence theory
Marcos V. de S. Silva, Carlos F. S. Pereira, Bruna Bragato +3
The paper investigates wormhole solutions in a k‑essence theory coupled to a phantom scalar field, deriving the scalar field, potential, and electromagnetic functions for electrica…
Light propagation and gravitational lensing effects in charged Kalb-Ramond spacetime in nonlinear electrodynamics
C. F. S. Pereira, Marcos V. de S. Silva, A. R. Soares +3
In this work, we theoretically investigate the deflection of light for strong- and weak-field regimes in the background of an electrically charged BH described in Kalb-Ramond gravi…
Light propagation and quasinormal modes of a topologically charged Schwarzschild-Klinkhamer wormhole
C. F. S. Pereira, H. Belich, A. R. Soares +3
In this work, we present a theoretical analysis of null geodesics, critical photon orbits, and shadow formation associated with a wormhole generated by a geometric defect. The prop…
Roche limit and stellar disruption in the Simpson--Visser spacetime
Marcos V. de S. Silva
Due to the tidal forces that a black hole can produce, certain types of compact objects may undergo disruption as they approach the black hole. This disruption point is known as th…
Tidal dynamics and stellar disruption in charged Kalb-Ramond black holes in nonlinear electrodynamics
Ednaldo L. B. Junior, Herlan N. Lemos, Marcos V. de S. Silva
We investigate tidal forces, geodesic deviation, and tidal disruption in the black hole spacetime described by the Kalb-Ramond-ModMax solution, where electromagnetic nonlinearity i…
Scalar and spinor fields in gravitating cosmic string spacetimes
Marcos Silva, Azadeh Mohammadi
We study the scattering behavior of scalar and spinor fields in the background of a gravitating cosmic string spacetime. The model explored here for the background vortex is non-ab…
