On the Plane Resonant Rotations of a Satellite with a Spherical Damper in an Elliptical Orbit
AbstractThe influence of internal dissipative forces on rotational motion of a satellite in an elliptical orbit is studied in the context of the...

Specifics of the Distribution of Orbits of Long-Period Comets in the Inner Part of the Oort Cloud
Abstract —We investigate statistical patterns in the distribution of the orbits of long-period comets that belong to the inner region of the Oort...

On the Evolution of Orbits in a Photo-Gravitational Circular Three-Body Problem: The Inner Problem
AbstractWe consider the spatial restricted circular three-body problem in the nonresonant case. The massless body (satellite) is assumed to have a...

Lambda Perturbations of Keplerian Orbits in the Expanding Universe
AbstractTo estimate the influence of “dark energy” on Keplerian orbits, we solve the general-relativistic equations of motion of a test particle in...

Constant-r geodesics in the Painlevé–Gullstrand form of Lense–Thirring spacetime
Herein we explore the non-equatorial constant-r (“quasi-circular”) geodesics (both timelike and null) in the Painlevé–Gullstrand variant of the...

Circular orbits and accretion process near a regular phantom black hole
The relativistic accretion onto astrophysical compact objects such as black holes and neutron stars is the natural phenomena for releasing energy,...

Detection of Asteroid Impact Orbits Using Conditional Minimization of the Distance to the Earth
Abstract—A method has been developed for detecting impact orbits of asteroids in the confidence ellipsoid of the initial parameters of motion. The...

Cuspy and fractured black hole shadows in a toy model with axisymmetry
Cuspy shadow was first reported for hairy rotating black holes, whose metrics deviate significantly from the Kerr one. The non-smooth edge of the...

Naked Singularities and Black Hole Killing Horizons
In this chapter, we study special photon orbits defined by means of Killing vectors and present a framework based on the properties of such null...

Orbital analysis in the gravitational potential of elongated asteroids
This work studies the motion around irregular elongated asteroids through two approaches. Firstly, it revisits the dipole-segment model, identifying...

Analytical methods in celestial mechanics: satellites’ stability and galactic billiards
In this paper, two models of interest for Celestial Mechanics are presented and analysed, using both analytic and numerical techniques, from the...

A Search for Young Asteroid Pairs with Close Orbits
Abstract—We analyzed the dynamic evolution of a number of young asteroid pairs in close orbits in order to constrain their ages. Several methods of...

Simulation of orbits around the galactic centre black hole with a relativistic Newtonian analogous potential
We study the dynamics of a test particle around a central mass taking into account general relativistic effects within the formalism of Lagrangian...

Evolution of orbits about comets with arbitrary comae
Spacecraft and natural objects orbiting an active comet are perturbed by gas drag from the coma. These gases expand radially at about 0.5 km/s, much...

Particle dynamics in spherically symmetric electro-vacuum instantons
In this paper, we study the geodesic motion in spherically symmetric electro-vacuum Euclidean solutions of the Einstein equation. There are two kinds...

Comparison of the Orbital Properties of the Milky Way Globular Clusters from the Data of the Gaia DR2 and EDR3 Catalogs
AbstractWe provide new values of the orbital parameters of 152 globular clusters, which are calculated using the new mean proper motions obtained...

The capture probability of Dawn into ground-track resonances with Vesta
The Dawn spacecraft approached the asteroid Vesta and descended from a high-altitude mission orbit to a low-altitude mission orbit using low-thrust...

Mathematical Modeling of Spacecraft in Magnetosphere Plasma
AbstractThe Coulomb software complex for modeling of spacecraft charging in magnetosphere plasma in high and low Earth orbits is described. Physical...
