Abstract

© 2016, Springer Science+Business Media Dordrecht. We analyze the families of central configurations of the spatial 5-body problem with four masses equal to 1 when the fifth mass m varies from 0 to (Formula presented.). In particular we continue numerically, taking m as a parameter, the central configurations (which all are symmetric) of the restricted spatial ( (Formula presented.) )-body problem with four equal masses and (Formula presented.) to the spatial 5-body problem with equal masses (i.e. (Formula presented.) ), and viceversa we continue the symmetric central configurations of the spatial 5-body problem with five equal masses to the restricted ( (Formula presented.) )-body problem with four equal masses. Additionally we continue numerically the symmetric central configurations of the spatial 5-body problem with four equal masses starting with (Formula presented.) and ending in (Formula presented.) , improving the results of Alvarez-Ramírez et al. (Discrete Contin Dyn Syst Ser S 1: 505–518, 2008). We find four bifurcation values of m where the number of central configuration changes. We note that the central configurations of all continued families varying m from 0 to (Formula presented.) are symmetric.
