Symmetries in central-force problems [PDF]
The two-body problem in central fields (reducible to a central-force problem) models a lot of concrete astronomical situations. The corresponding vector fields (in Cartesian and polar coordinates, extended via collision-blow-up and infinity-blow-up ...

Editorial for the Special Issue “Relativistic Astrophysics”
Relativistic Astrophysics is the branch of astrophysics that studies astronomical phenomena and celestial bodies, for which classical mechanics and Newton’s law of gravitation are inapplicable to creation of suitable models and we have to generalize ...

The proximities of asteroids and critical points of the distance function [PDF]
The proximities are important for different purposes, for example to evaluate the risk of collisions of asteroids or comets with the Solar-System planets.

A new approach to determining the solar galactocentric distance, R0, from the geometry of spiral-arm segments is proposed. Geometric aspects of the problem are analyzed and a simplified three-point method for estimating R0 from objects in a spiral ...

Survey of secular resonances in the asteroid belt [PDF]
Using a recently introduced synthetic method to compute the asteroid secular frequencies (Knežević and Milani 2019), in this paper we survey the locations of secular resonances in the 9 dynamically distinct zones of the asteroid belt.

Daemons and DAMA: Their Celestial-Mechanics Interrelations [PDF]
The assumption of the capture by the Solar System of the electrically charged Planckian DM objects (daemons) from the galactic disk is confirmed not only by the St.Petersburg (SPb) experiments detecting particles with ...

Quantitative predictions with detuned normal forms [PDF]
The phase-space structure of two families of galactic potentials is approximated with a resonant detuned normal form. The normal form series is obtained by a Lie transform of the series expansion around the minimum of the original Hamiltonian. Attention is focused on the quantitative predictive ability of the normal form. We find analytical expressions

Gamification in studying celestial mechanics using Kerbal Space Program
The rapid development of technologies and their implementation in the educational process provide an opportunity to apply gamification, that is, the use of game mechanics and elements for in-depth study of a complex technical discipline.

On the foundations of general relativistic celestial mechanics [PDF]
Towards the end of nineteenth century, Celestial Mechanics provided the most powerful tools to test Newtonian gravity in the solar system, and led also to the discovery of chaos in modern science.
