Behaviours of rip cosmological models in gravity
Amit Samaddar, S. Surendra Singh, Shah Muhammad +1
In this study, the Universe's rip cosmology theories have been provided for the gravity theory, where and stand for the non-metricity scalar and boundary term. We…
Effect of Multipole Moments in the Weak Field Limit of a Black Hole Plus Halo Potential
F. L. Dubeibe, Tareq Saeed, Euaggelos E. Zotos
In this paper, we consider a Newtonian system whose relativistic counterpart describes a superimposed halo with a black hole. Our aim is to determine how the quadrupole and octupol…
Orbit classification in a disk galaxy model with a pseudo-Newtonian central black hole
Euaggelos E. Zotos, F. L. Dubeibe, André F. Steklain +1
We numerically investigate the motion of stars on the meridional plane of an axially symmetric disk galaxy model, containing a central supermassive black hole, represented by the P…
Short-term stability of particles in the WD J0914+1914 white dwarf planetary system
Euaggelos E. Zotos, Dimitri Veras, Tareq Saeed +1
Nearly all known white dwarf planetary systems contain detectable rocky debris in the stellar photosphere. A glaring exception is the young and still evolving white dwarf WD J0914+…
The grain size survival threshold in one-planet post-main-sequence exoplanetary systems
Euaggelos E. Zotos, Dimitri Veras
The size distribution and orbital architecture of dust, grains, boulders, asteroids, and major planets during the giant branch phases of evolution dictate the preponderance and obs…
Fractal basins of convergence of a seventh-order generalized Hénon-Heiles potential
E. E. Zotos, F. L. Dubeibe, A. Riaño-Doncel
This article aims to investigate the points of equilibrium and the associated convergence basins in a seventh-order generalized Hénon-Heiles potential. Using the well-known Newton-…
