Stacked Central Configurations for the Spatial Nine-Body Problem. (13th June 2013) - Xia, Su
Abstract : We show the existence of the twisted stacked central configurations for the 9-body problem. More precisely, the position vectors x 1, x 2, x 3, x 4, and x 5 are at the vertices of a square pyramid Σ ; the position vectors x 6, x 7, x 8, and x 9 are at the vertices of a square Π .
