A family of stacked central configurations in the planar five-body problem
Lino Cornelio, J.; Álvarez Ramírez, Martha; Cors Iglesias, Josep Maria (2017-11)
Article
Accés obertWe study planar central configurations of the five-body problem where three bodies, (Formula presented.) and (Formula presented.), are collinear and ordered from left to right, while the other two, (Formula presented.) and ... -
A four-body convex central configuration with perpendicular diagonals is necessarily a kite
Corbera, Montserrat; Cors Iglesias, Josep Maria; Roberts, Gareth E. (2018-07-01)
Article
Accés obertWe prove that any four-body convex central configuration with perpendicular diagonals must be a kite configuration. The result extends to general power-law potential functions, including the planar four-vortex problem. -
A note on a family of non-gravitational central force potentials in dimension one
Alvarez-Ramírez, M.; Corbera Subirana, Montserrat; Cors Iglesias, Josep Maria; García, A. (Elsevier, 2017-12-01)
Article
Accés obertIn this work, we study a one-parameter family of differential equations and the different scenarios that arise with the change of parameter. We remark that these are not bifurcations in the usual sense but a wider phenomenon ... -
A special family of stacked central configurations: Lagrange plus Euler in one
Lino Cornelio, J.; Álvarez Ramírez, Martha; Cors Iglesias, Josep Maria (2019-06)
Article
Accés obertWe show the existence of a family of stacked central configurations in the planar five-body problem with a special property. Three bodies m1, m2 and m3, ordered from left to right, are collinear and form an Euler central ... -

Bifurcation of relative equilibria of the (1+3)-body problem
Corbera, M.; Cors Iglesias, Josep Maria; Llibre Saló, Jaume; Moeckel, Richard (2015-04-02)
Article
Accés obertWe study the relative equilibria of the limit case of the planar Newtonian 4-body problem when three masses tend to zero, the so-called (1+3)-body problem. Depending on the values of the infinitesimal masses the number of ... -
Central configurations in the five-body problem: rhombus plus one
Lino Cornelio, J.; Alvarez Ramírez, Martha; Cors Iglesias, Josep Maria (2021-05-20)
Article
Accés obertWe show the existence of central configurations in the planar five-body problem where four bodies are located at the vertices of a rhombus, called rhombus plus one central configurations. Concretely we prove analytically ... -
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, ... -
Classifying four-body convex central configurations
Corbera, Montserrat; Cors Iglesias, Josep Maria; Roberts, Gareth E. (2019-07-01)
Article
Accés obertWe classify the full set of convex central configurations in the Newtonian planar four-body problem. Particular attention is given to configurations possessing some type of symmetry or defining geometric property. Special ... -
Convexity and symmetry of central configurations in the five-body problem: Lagrange plus two
Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Fernandes, Antonio Carlos; Vidal Díaz, Claudio (2021-07-10)
Article
Accés obertWe study convexity and symmetry of central configurations in the five body problem when three of the masses ara located at the vertices of an equilateral triangle, that we call Lagrange plus two central configurations. ... -
Coorbital periodic orbits in the three body problem
Cors Iglesias, Josep Maria; Hall, G.R. (2003-05)
Article
Accés obertWe consider the dynamics of coorbital motion of two small moons about a large planet which have nearly circular orbits with almost equal radii. These moons avoid collision because they switch orbits during each close ... -
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 ... -
Four-body co-circular central configurations
Cors Iglesias, Josep Maria; Roberts, Gareth E. (2012-02)
Article
Accés obertWe classify the set of central configurations lying on a common circle in the Newtonian four-body problem. Using mutual distances as coordinates, we show that the set of four-body co-circular central configurations with ... -
