Gamification in studying celestial mechanics using Kerbal Space Program

Авіаційно-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.

Degenerate billiards in celestial mechanics [PDF]

Regular and Chaotic Dynamics, 2017
In an ordinary billiard trajectories of a Hamiltonian system are elastically reflected after a collision with a hypersurface (scatterer). If the scatterer is a submanifold of codimension more than one, we say that the billiard is degenerate. Degenerate billiards appear as limits of systems with singularities in celestial mechanics.

The Proximities of Asteroids and Critical Points of the Distance Function [PDF]

Serbian 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.

Semantic primitives and compositionality: An Annual Review of Information Science and Technology (ARIST) paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract The term semantic primitives refers to a set of basic, atomic concepts from which all other (compound) concepts are constructed. It presupposes the principle of compositionality—the idea that complex items or expressions can be formed by combining simpler constituents.

Empirical Stability Criteria for 3D Hierarchical Triple Systems. I. Circumbinary Planets

The Astronomical Journal
In this work we revisit the problem of the dynamical stability of hierarchical triple systems with applications to circumbinary planetary orbits. We derive critical semimajor axes based on simulating and analyzing the dynamical behavior of 3 × 10 ^8 ...

Titius-Bode’s Relation and Distribution of Exoplanets [PDF]

Journal of Astronomy and Space Sciences, 2010
The distance distribution in our planetary system has been a controversial matter. Two kinds of important issues on Titius-Bode’s relation have been discussed up to now: one is if there is a simple mathematical relation between distances of natural ...
