Small Orbits

open access: yesPhysical Review D, 2011
We study both the "large" and "small" U-duality charge orbits of extremal black holes appearing in D = 5 and D = 4 Maxwell-Einstein supergravity theories with symmetric scalar manifolds.

Orbit Functions [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2006
In the paper, properties of orbit functions are reviewed and further developed. Orbit functions on the Euclidean space E_n are symmetrized exponential functions.

Orbits [PDF]

open access: yesSymposium - International Astronomical Union, 1987
Orbits that respect at least three isolating integrals of motion have very special structures in phase space. The main characteristics of this structure are reviewed, and the concrete examples that are provided by orbits in Stäckel potentials, are discussed.

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

open access: yes, 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]

open access: yes, 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 ...

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

open access: yes, 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

The dynamical environment of the primary in the triple asteroid (45) Eugenia

open access: yesOpen Astronomy, 2020
We investigated the dynamical behavior in the potential of the primary in the triple asteroid (45) Eugenia with the calculation of the full gravitational potential caused by its 3D irregular shape.

The hot orbit: Orbital cellulitis

open access: yesMiddle 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

Deformations of circle-valued Morse functions on 2-torus

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2021
In this paper we give an algebraic description of fundamental groups of orbits of circle-valued Morse functions on T2 with respect to the action of the group of diffeomorphisms of ...
