Spin-orbit coupling and chaotic rotation for eccentric coorbital bodies

TL;DR

This paper investigates how co-orbital companions affect spin-orbit resonances, leading to chaotic rotation in eccentric bodies due to resonance overlap caused by spin-orbit coupling.

Contribution

It introduces the impact of co-orbital companions on spin-orbit resonance splitting and chaos, expanding understanding of rotational dynamics in such systems.

Findings

Co-orbital companions cause splitting of spin-orbit resonances.

Resonance overlap induces chaotic rotation in eccentric bodies.

Chaotic behavior depends on co-orbital configuration and eccentricity.

Abstract

The presence of a co-orbital companion induces the splitting of the well known Keplerian spin-orbit resonances. It leads to chaotic rotation when those resonances overlap.
