  • 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
    Open Access
    We 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.
  • Classifying four-body convex central configurations

    We 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 ...
  • Four-body co-circular central configurations 

    Cors Iglesias, Josep Maria; Roberts, Gareth E. (2012-02)
    Article
    Open Access
    We 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 ...
  • Overview of the Chemistry-Aerosol Mediterranean Experiment/aerosol direct radiative forcing on the Mediterranean climate (ChArMEx/ADRIMED) summer 2013 campaign 

    Mallet, Marc; Dulac, F; Formenti, P; Nabat, Pierre; Sciare, J.; Roberts, Gareth E.; Pelon, Jacques; Ancellet, Gerard; Tanré, Didier; Parol, F; Dejean, C.; Brogniez, G.; di Sarra, G; Alados Arboledas, Lucas; Arndt, Dorthe; Auriol, F.; Blarel, L.; Bourrianne, T.; Chazette, P; Chevaillier, S.; Claeys, Maxim; D'Anna, B.; Derimian, Y.; Desboeufs, K.; Di Iorio, Tatiana; Doussin, J.F.; Durand, Pierre; Feron, A.; Franay, E.; Gaimoz, C.; Goloub, Philppe; Gomez Amo, J.L.; Granados Muñoz, María José; Sicard, Michaël (2016)

    The Chemistry-Aerosol Mediterranean Experiment (ChArMEx; http://charmex.lsce.ipsl.fr) is a collaborative research program federating international activities to investigate Mediterranean regional chemistry-climate interactions. ...
  • Uniqueness results for co-circular central configurations for power-law potentials 

    Cors Iglesias, Josep Maria; Hall, G.R.; Roberts, Gareth E. (2014-05-10)
    Article
    Open Access
    For a class of potential functions including those used for the planar n-body and n-vortex problems, we investigate co-circular central configurations whose center of mass coincides with the center of the circle containing ...
