Central configurations of the planar coorbial satellite problem
Cors Iglesias, Josep Maria; Llibre Saló, Jaume; Ollé Torner, Mercè (2004-10)
Article
Accés obertWe study the planar central configurations of the 1 +n body problem where one mass is large and the other n masses are infinitesimal and equal. We find analytically all these central configurations when 2=n=4. Numerically, ... -
Central configurations of the planar coorbital satellite problem
Cors Iglesias, Josep Maria; Llibre Saló, Jaume; Ollé Torner, Mercè (2003)
Article
Accés obertWe study the planar central configurations of the 1 + n body problem where one mass is large and the other n masses are infinitesimal and equal. We find analytically all these central configurations when 2 ≤ n ≤ 4. Numerically, ... -
Confinement around the Vertical Family of Periodic Orbits close L<sub>4</sub> and L<sub>5</sub>
Ollé Torner, Mercè; Pacha Andújar, Juan Ramón; Villanueva Castelltort, Jordi (2001)
Article
Accés obertWe consider the spatial restricted three body problem (RTBP) for values of the mass parameter close to µRouth. We analyse the dynamics around the vertical periodic orbits which are born at the equilateral equilibrium ... -
Dinàmica de varietats espacials: les autopistes de l’univers
Ollé Torner, Mercè; Barrabés Vera, Esther (2019-12-20)
Article
Accés obertEn aquest article volem il.lustrar com la comprensió de la dinàmica d’alguns models de la mecànica celeste permet explicar alguns fenòmens astronòmics i dissenyar missions realistes a l’espai. El model paradigmàtic usat ... -
Dynamical aspects of multi-round horseshoe-shaped homoclinic orbits in the RTBP
Ollé Torner, Mercè; Barrabés Vera, Esther (2009-11)
Article
Accés restringit per política de l'editorialWe consider the planar restricted three-body problem and the collinear equilibrium point L3, as an example of a center×saddle equilibrium point in a Hamiltonian with two degrees of freedom.We explore numerically the ... -
Dynamics and bifurcation near the transition from stability to complex instability

Dynamics and bifurcation near the transition from stability to complex instability: an analytical approach using normal forms
Ollé Torner, Mercè; Pacha Andújar, Juan Ramón; Villanueva Castelltort, Jordi (1998)
Article
Accés obertWe consider a Hamiltonian of three degrees of freedom and a family of periodic orbits with a transition from stability to complex instability, such that there is an irrational collision of the Floquet eigenvalues of opposite ... -
Dynamics close to a non semi-simple 1: -1 resonant periodic orbit.
Ollé Torner, Mercè; Pacha Andújar, Juan Ramón; Villanueva Castelltort, Jordi (2003)
Article
Accés obertIn this work, our target is to analyze the dynamics around the $1:-1$ resonance which appears when a family of periodic orbits of a real analytic three-degree of freedom Hamiltonian system changes its stability from ... -
Dynamics of the parabolic restricted three-body problem
Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Ollé Torner, Mercè (2015-12-01)
Article
Accés obertThe main purpose of the paper is the study of the motion of a massless body attracted, under the Newton's law of gravitation, by two equal masses moving in parabolic orbits all over in the same plane, the planar parabolic ... -
Ejection-collision orbits in the Restricted three-body problem
Ollé Torner, Mercè; Rodríguez del Río, Óscar; Soler Villanueva, Jaume (2018-02)
Article
Accés obertIn this paper we analyse the ejection-collision (EC) orbits of the planar restricted three body problem. Being µ¿¿¿(0, 0.5] the mass parameter, and taking the big (small) primary with mass (µ), an EC orbit will be an orbit ... -
Ejection-collision orbits in the symmetric collinear four–body problem
Álvarez Ramírez, Martha; Barrabés Vera, Esther; Medina, M.; Ollé Torner, Mercè (2019-06-15)
Article
Accés obertIn this paper, we consider the collinear symmetric four-body problem, where four masses and a¿>¿0, are aligned in this order and move symmetrically about their center of mass. We introduce regularized variables to deal ... -
Ejection–collision orbits in two degrees of freedom problems in celestial mechanics
Alvarez Ramírez, Martha; Barrabés Vera, Esther; Medina, M.; Ollé Torner, Mercè (Springer Nature, 2021-08-01)
Article
Accés obertIn a general setting of a Hamiltonian system with two degrees of freedom and assuming some properties for the undergoing potential, we study the dynamics close and tending to a singularity of the system which in models of ... -
