The dynamical evolution of close-in binary systems formed by a super-Earth and its host star: Case of the Kepler-21 system
(EDP Sciences, 2020-09)
Aims. The aim of this work is to develop a formalism for the study of the secular evolution of a binary system which includes interaction due to the tides that each body imparts on the other. We also consider the influence ...
Quasi circular orbits around prolate bodies
(2021-09-01)
Recent observations of stellar occultations have revealed rings of particles around non-planetary bodies of the Solar system. These bodies are irregular and can be modelled by ellipsoids. In the context of numerical ...
Regular and chaotic orbits in a self-consistent triaxial stellar system with slow figure rotation
(Springer, 2006-10)
We created a self-consistent triaxial stellar system through the cold disipationless collapse of 100,000 particles whose evolution was followed with a multipolar code. The resulting system rotates slowly even though its ...
Spatial structure of regular and chaotic orbits in a self-consistent triaxial stellar system
(Springer, 2005-03)
We created a triaxial stellar system through the cold dissipationless collapse of 100,000 particles whose evolution was followed with a multipolar code. Once an equilibrium system had been obtained, the multipolar expansion ...
A three dimensional investigation of two dimensional orbits
(Springer, 2012-01)
Orbits in the principal planes of triaxial potentials are known to be prone to unstable motion normal to those planes, so that three dimensional investigations of those orbits are needed even though they are two dimensional. ...
Spatial structure of regular and chaotics orbits in selfconsistent models of galactic satellites
(Springer, 2004-12)
In several previous papers we had investigated the orbits of the stars that make up galactic satellites, finding that many of them were chaotic. Most of the models studied in those works were not self-consistent, the single ...
Mass of spiral galaxies by means of a maximum disc model
(2018-07-30)
Maximum disc mass models for a set of spiral galaxies from the Ursa Major Cluster are presented. We construct the models using the Hunther method and the particular solutions are chosen in such away that the circular ...
