Central Configurations and Action Minimizing Orbits in Kite Four-Body Problem

Abstract EN

In the current article, we study the kite four-body problems with the goal of identifying global regions in the mass parameter space which admits a corresponding central configuration of the four masses.

We consider two different types of symmetrical configurations.

In each of the two cases, the existence of a continuous family of central configurations for positive masses is shown.

We address the dynamical aspect of periodic solutions in the settings considered and show that the minimizers of the classical action functional restricted to the homographic solutions are the Keplerian elliptical solutions.

Finally, we provide numerical explorations via Poincaré cross-sections, to show the existence of periodic and quasiperiodic solutions within the broader dynamical context of the four-body problem.
