Stabilizing periodic orbits above the elliptic plane in the solar sail 3-body problem [PDF]

open access: yes, 2008
We consider periodic orbits high above the ecliptic plane in the Elliptic Restricted Three-Body Problem where the third massless body is a solar sail.

Comet like periodic orbits in the N-body problem [PDF]

open access: yes, 1994
Take any nonresonant relative equilibrium solution of the N-body problem. Then there is a periodic solution of the (N + 1)-body problem where N of the particles remain close to the relative equilibrium solution and the remaining particle is close to a ...

C-cross products and a generalized mechanical N-body problem

open access: yesElectronic Journal of Differential Equations, 2000
For each finite dimensional real vector space X we construct a C*-algebra A graded by the lattice of all subspaces of X and we compute its quotient with respect to the algebra of compact operators.

Exemplos de configurações centrais planares encaixantes

open access: yesRevista Brasileira de Ensino de Física
Neste artigo estudamos configurações centrais planares encaixantes para o problema de n corpos em mecânica celeste quando n = 4, n = 8 e n = 12. Determinamos condições suficientes para a existência de tais configurações com os corpos nos vértices de ...

Photodisintegration of 9Be and the importance of the unbound 1/2+ state

open access: yesEPJ Web of Conferences, 2016
The photodisintegration cross section of the 9Be(1/2+) state is investigated in a framework of the α + α + n three-body model. The 1/2+ state of 9Be locates just above the three-body threshold, and the s-wave neutron property of this state is a long ...

Self‐Regulated Learning Meets AI: Reinterpreting Self‐Regulation, Co‐Regulation, and Socially Shared Regulation in Human–AI Interaction

open access: yesNew Directions for Adult and Continuing Education, EarlyView.
ABSTRACT Advancing artificial intelligence (AI) has transformed learning and work, yet higher education and professional development programs have not systematically equipped learners for AI‐prevalent environments. This lack of preparation creates uncertainty regarding control, responsibility, trust, and accountability.

Dynamical and Secular Stability of Mutually Inclined Planetary Systems

open access: yesThe Astrophysical Journal
Multiple analytical, semi-analytical, and empirical stability criteria have been derived in the literature for two-planet systems. But, the dependence of the stability limit on the initial mutual inclination between the inner and outer orbits is not well

NBODYCL: A Program to Generate Regularized Classical Trajectories for the n–Body Coulomb Problem

open access: yesAtoms
A program package for calculating regularized classical trajectories for Coulomb n–body problem is developed. The Coulomb singularities from the equations of motion are removed by transformations of variables including the time.

Exact ground state of several N-body problems with an N-body potential [PDF]

open access: yesJournal of Mathematical Physics, 1999
The exact (bosonic) ground state and a class of excited states are obtained for several Calogero-type N-body problems in D dimensions when the N bodies are also interacting via an N-body potential of the form −e2/Σri2.
