A dynamical study of Hilda asteroids in the Circular and Elliptic RTBP

Autor: Jorba, Àngel, Nicolás, Begoña, Rodríguez, Óscar

Publikováno v: Chaos, Volume 34, Issue 12, 123116 (2024)

The Hilda group is a set of asteroids whose mean motion is in a 3:2 orbital resonance with Jupiter. In this paper we use the planar Circular Restricted Three-Body Problem (CRTBP) as a dynamical model and we show that there exists a family of stable p

Dynamics Around the Earth-Moon Triangular Points in the Hill Restricted 4-Body Problem

Autor: Peterson, Luke T., Brown, Gavin, Jorba, Àngel, Scheeres, Daniel

This paper investigates the motion of a small particle moving near the triangular points of the Earth-Moon system. The dynamics are modeled in the Hill restricted 4-body problem (HR4BP), which includes the effect of the Earth and Moon as in the circu

Numerical computation of high-order expansions of invariant manifolds of high-dimensional tori

Autor: Gimeno, Joan, Jorba, Àngel, Nicolás, Begoña, Olmedo, Estrella

In this paper we present a procedure to compute reducible invariant tori and their stable and unstable manifolds in stroboscopic Poincar\'e maps. The method has two steps. In the first step we compute, by means of a quadratically convergent scheme, t

Triggering recollisions with XUV pulses: Imprint of recolliding periodic orbits

Autor: Dubois, Jonathan, Jorba, Angel

We consider an electron in an atom driven by an infrared (IR) elliptically polarized laser field after its ionization by an ultrashort extreme ultraviolet (XUV) pulse. We find that, regardless of the atom species and the laser ellipticity, there exis

Braids with the symmetries of Platonic polyhedra in the Coulomb (N+1)-body problem

Autor: Fenucci, Marco, Jorba, Àngel

Publikováno v: Communications in Nonlinear Science and Numerical Simulations, Volume 83, April 2020, 105105

We take into account the Coulomb (N + 1)-body problem with N = 12, 24, 60. One of the particles has positive charge Q > 0, and the remaining N have all the same negative charge q < 0. These particles move under the Coulomb force, and the positive cha
