Editorial for the Special Issue “Relativistic Astrophysics”

open access: yesUniverse, 2022
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 ...

Tying celestial mechanics to Earth’s ice ages

open access: yesPhysics today, 2020
Gradual falls and sharp rises in temperature for millions of years have profoundly affected living conditions on the planet and, consequently, our own evolution.

Ephemerides and Celestial Mechanics [PDF]

open access: yesHighlights of Astronomy, 1986
When solving some abstract problems in mechanics related to the dynamics of bodies and systems, the notion of an inertial frame of reference is introduced in an apparently clear and natural way by simply drawing its coordinate axes and then paying no further attention to the system of reference which is then taken for granted.

Applications of KS - variables in celestial mechanics

open access: yesBibechana, 2010
This paper deals with the transformation of KS-Variables and canonically conjugate variables from sideral (inertial) to synodic (rotating) form and their applications in "the circular restricted problem of three bodies in three-dimensional coordinate ...

The proximities of asteroids and critical points of the distance function [PDF]

open access: yesSerbian Astronomical Journal, 2010
The proximities are important for different purposes, for example to evaluate the risk of collisions of asteroids or comets with the Solar-System planets.

On the Possibility of Determining the Distance to the Galactic Center from the Geometry of Spiral Arm Segments

open access: yesOpen Astronomy, 2015
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 ...

The Relative Inertiality - The Relative Mechanical Movement of Bodies in Outer Space [PDF]

open access: yesINCAS Bulletin
Even though classical mechanics states that it is not possible to find an inertial reference frame, relative measurements are used to determine the mechanical behaviour of celestial bodies with very small dimensions compared to the distances between them.

On the Proper Treatment of Dynamics in Cognitive Science

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract This essay examines the relevance of dynamical ideas for cognitive science. On its own, the mere mathematical idea of a dynamical system is too weak to serve as a scientific theory of anything, and dynamical approaches within cognitive science are too rich and varied to be subsumed under a single “dynamical hypothesis.” Instead, after first ...

Gamification in studying celestial mechanics using Kerbal Space Program

open access: yesАвіаційно-космічна техніка та технологія
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.
