Title:	A Four-body convex central configuration with perpendicular diagonals is necessarily a kite
Author:	Corbera Subirana, Montserrat; Cors Iglesias, Josep Maria; Roberts, Gareth E.
Abstract:	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.
