Natural and sail-displaced doubly-symmetric Lagrange point orbits for polar coverage [PDF]

, 2012
This paper proposes the use of doubly-symmetric, eight-shaped orbits in the circular restricted three-body problem for continuous coverage of the high-latitude regions of the Earth. These orbits, for a range of amplitudes, spend a large fraction of their

Orbital Degeneracy Loci II: Gorenstein Orbits [PDF]

International Mathematics Research Notices, 2018
AbstractIn [3] we introduced orbital degeneracy loci as generalizations of degeneracy loci of morphisms between vector bundles. Orbital degeneracy loci can be constructed from any stable subvariety of a representation of an algebraic group. In this paper we show that their canonical bundles can be conveniently controlled in the case where the affine ...

Evolution of ambiguous numbers under the actions of a Bianchi group

Journal of Taibah University for Science, 2020
In this paper we study some combinatorial properties of biquadratic irrational number field ${\mathbb{Q}}( {i,\sqrt{3} } ) $, under the action of a Bianchi group ${\Gamma _3} = PSL({2,{O_3}} ) $.

The hot orbit: Orbital cellulitis

Middle East African Journal of Ophthalmology, 2012
Orbital cellulitis is an uncommon condition previously associated with severe complications. If untreated, orbital cellulitis can be potentially sight and life threatening. It can affect both adults and children but has a greater tendency to occur in the pediatric age group. The infection most commonly originates from sinuses, eyelids or face, retained

Magnetized and Magnetically Charged Particles Motion around Regular Bardeen Black Hole in 4D Einstein Gauss–Bonnet Gravity

Universe, 2022
In this paper, we study the horizon properties and scalar invariants of the spacetime around a regular black hole (BH) in 4D Einstein Gauss-Bonnet (4D EGB) gravity.

A unified framework for the orbital structure of bars and triaxial ellipsoids [PDF]

, 2015
We examine a large random sample of orbits in two self-consistent simulations of N-body bars. Orbits in these bars are classified both visually and with a new automated orbit classification method based on frequency analysis.

Solar sail orbits at artificial Sun-Earth libration points [PDF]

, 2005
In this Note a new family of solar sail orbits will be investigated in the sun-Earth circular restricted three-body problem. It will be shown that periodic orbits can be developed that are displaced above or below the plane of the restricted three-body ...

Orbits in the H2O molecule [PDF]

, 2001
We study the forms of the orbits in a symmetric configuration of a realistic model of the H2O molecule with particular emphasis on the periodic orbits. We use an appropriate Poincar\'e surface of section (PSS) and study the distribution of the orbits on ...

Observational data and orbits of the asteroids discovered at the Molėtai Observatory in 2010–2012

Open Astronomy, 2017
This paper is devoted to the discovery of asteroids at the Molėtai Astronomical Observatory (MAO) in 2010- 2012 together with the orbital analysis of two dynamically interesting Near Earth Objects (NEOs) discovered at the MAO, namely 2006 SF77 and 2010 ...

A Note on Graphs with Prescribed Orbit Structure

Entropy, 2019
This paper presents a proof of the existence of connected, undirected graphs with prescribed orbit structure, giving an explicit construction procedure for these graphs. Trees with prescribed orbit structure are also investigated.
