Quasinormal modes of nonlocal gravity black holes
Rocco D'Agostino, Vittorio De Falco
We present a comprehensive study of the quasinormal modes of a new class of nonlocal static and spherically symmetric black hole (BH) solutions within the framework of the revised…
Analytical coordinate time at the second post-Newtonian order
Vittorio De Falco, Marco Gallo
We derive the analytical expression of the coordinate time in terms of the eccentric anomaly at the second post-Newtonian order in General Relativity for a compact binary s…
Can wormholes mirror the quasi-normal mode spectrum of Schwarzschild black holes?
Ciro De Simone, Vittorio De Falco, Salvatore Capozziello
Wormholes are exotic compact objects characterized by the absence of essential singularities and horizons, acting as slender bridges linking two distinct regions of spacetime. Desp…
Epicyclic frequencies in static and spherically symmetric wormhole geometries
Vittorio De Falco, Mariafelicia De Laurentis, Salvatore Capozziello
The measurement of the epicyclic frequencies is a widely used astrophysical technique to infer information on a given self-gravitating system and on the related gravity background.…
Timescales of the chaos onset in the general relativistic Poynting-Robertson effect
Vittorio De Falco, William Borrelli
It has been proved that the general relativistic Poynting-Robertson effect in the equatorial plane of Kerr metric shows a chaotic behavior for a suitable range of parameters. As a…
Reconstructing wormhole solutions in curvature based Extended Theories of Gravity
Vittorio De Falco, Emmanuele Battista, Salvatore Capozziello +1
Static and spherically symmetric wormhole solutions can be reconstructed in the framework of curvature based Extended Theories of Gravity. In particular, extensions of the General…
Testing wormhole solutions in extended gravity through the Poynting-Robertson effect
Vittorio De Falco, Emmanuele Battista, Salvatore Capozziello +1
We develop a model-independent procedure to single out static and spherically symmetric wormhole solutions based on the general relativistic Poynting-Robertson effect and the exten…
Three-dimensional general relativistic Poynting-Robertson effect. III. Static and non-spherical quadrupolar massive source
Vittorio De Falco, Pavel Bakala, Maurizio Falanga
We investigate the three-dimensional motion of a test particle in the gravitational field generated by a non-spherical compact object endowed with a mass quadrupole moment, describ…
General relativistic Poynting-Robertson effect to diagnose wormholes existence: static and spherically symmetric case
Vittorio De Falco, Emmanuele Battista, Salvatore Capozziello +1
We derive the equations of motion of a test particle in the equatorial plane around a static and spherically symmetric wormhole influenced by a radiation field including the genera…
Neutron Star Radius-to-mass Ratio from Partial Accretion Disc Occultation as Measured through Fe K Line Profiles
Riccardo La Placa, Luigi Stella, Alessando Papitto +5
We present a new method to measure the radius-to-mass ratio (R/M) of weakly magnetic, disc-accreting neutron stars by exploiting the occultation of parts of the inner disc by the s…
Detection of chaos in the general relativistic Poynting-Robertson effect: Kerr equatorial plane
Vittorio De Falco, William Borrelli
The general relativistic Poynting-Robertson effect is a dissipative and non-linear dynamical system obtained by perturbing through radiation processes the geodesic motion of test p…
Stable attractors in the three-dimensional general relativistic Poynting-Robertson effect
Vittorio De Falco, Pavel Bakala
We prove the stability of the critical hypersurfaces associated with the three-dimensional general relativistic Poynting-Robertson effect. The equatorial ring configures to be as a…
Lagrangian formulation of the general relativistic Poynting-Robertson effect
Vittorio De Falco, Emmanuele Battista, Maurizio Falanga
We propose the Lagrangian formulation for describing the motion of a test particle in a general relativistic, stationary, and axially symmetric spacetime. The test particle is also…
