Co-evolution of 4 bodies

Presentation on four body dynamics prepared for "JH-meeting on stellar populations, gravitational dynamics and MOND-based cosmology" held in Jindrichuv Hradec on 24th November 2022.

The presentation covers the Keplerian orbits elements, Kozai-Lidov oscillations and a hierarchal four body setup. This four body setup results in evolution of orbital elements which is described by the VHS mechanism.

The presentation covers the presence of the VHS mechanism in various environments like the galactic centre and SMBH neighbourhood with relativistic effects.

Presentation files are attached below with some media from the presentations. Code to generate these plots and animations is called KepOrbs and is available on Github.
