Effective Geometry of the Bardeen Spacetimes: Gravitational Lensing and Frequency Mapping of Keplerian Disks
We study the appearance of Keplerian accretion disks in order to demonstrate and frequency shifting of the images of the Keplerian disks. We focus our attention representing an NED. Photons governing the appearance of the Kepler...

Optical effects related to Keplerian discs orbiting Kehagias-Sfetsos naked singularities
to the 'antigravity' effect, which causes an internal static sphere surrounded by Keplerian discs. We focus our attention on the optical effects related to the Keplerian accretion discs, constructing the optical appearance of the <...

Counter-rotating Keplerian discs around Kerr superspinars
The appearance of corotating Keplerian discs orbiting Kerr superspinars has been shown to be strongly dependent on the value of the superspinar spin in both that self-illumination is irrelevant for counter-rotating Keplerian discs o...

Disks Surrounding Be stars: A Stellar Evolution Perspective
There is evidence that at least some stars undergoing the Be phenomenon are single, almost critically rotating stars surrounded by viscous Keplerian disks. (2011) describing the properties of a stationary viscous Keplerian disk surr...

Radial and vertical epicyclic frequencies of Keplerian motion in the field of Kerr naked singularities. Comparison with the black hole case and possible instability of naked-singularity accretion
Relativistic Keplerian orbital frequency (?K) and related epicyclic frequencies (radial ?r, vertical ??) play an important role in the physics of accretion discs orbiting Kerr black holes ? quasiperiodic oscillations observed in microquasars...

Quasi-Keplerian parametrization for eccentric compact binaries in scalar-tensor theories at second post-Newtonian order and applications
The generalized quasi-Keplerian parametrization for compact binaries on eccentric bound orbits is established at second post-Newtonian (2PN) order in a class of massless scalar-tensor theories. This result is used to compute the orbit-averag...
