Abstract We investigate the dynamics of the (47171) Lempo triple system, also known by 1999 TC36. We derive a full 3D N-body model that takes into account the orbital and spin evolution of all bodies, which are assumed triaxial ellipsoids. We show that, for reasonable values of the shapes and rotational periods, the present best fitted orbital solution for the Lempo system is chaotic and unstable in short time-scales. The formation mechanism of this system is unknown, but the orbits can be…

We investigate the dynamical environment in the first announced triple asteroid system 87 Sylvia. The 3D shape of the primary is rebuilt from shape data using the polyhedral model method. The
Gargantuan chaotic gravitational three-body systems and their irreversibility to the Planck length
Chaos is present in most stellar dynamical systems and manifests itself through the exponential growth of small perturbations. Exponential divergence drives time irreversibility and increases the
The Onset of Chaos in Permanently Deformed Binaries from Spin–Orbit and Spin–Spin Coupling
Permanently deformed objects in binary systems can experience complex rotation evolution, arising from the extensively studied effect of spin–orbit coupling as well as more nuanced dynamics arising
The origin of (47171) Lempo-like Kuiper belt triple systems during binary–binary interactions
The trans-Neptunian triple Lempo–Paha–Hiisi is composed of a tight inner binary with components of similar size and an outer companion about half their size orbiting 10 times further away. Large
Spin-orbit coupling for close-in planets
We study the spin evolution of close-in planets in multi-body systems and present a very general formulation of the spin-orbit problem. This includes a simple way to probe the spin dynamics from the
The Excited Spin State of Dimorphos Resulting from the DART Impact
• High-fidelity numerical codes are essential for modeling the long-term spin evolution • DART may excite Dimorphos’ spin, leading to attitude instability and chaotic tumbling • Dimorphos is

Dynamical stability analysis of the HD 202206 system and constraints to the planetary orbits
Context. Long-term, precise Doppler measurements with the CORALIE spectrograph have revealed the presence of two massive companions to the solar-type star HD 202206. Although the three-body fit of
The chaotic motion of the solar system: A numerical estimate of the size of the chaotic zones
Abstract In a previous paper (J. Laskar, Nature 338, (237–238)), the chaotic nature of the Solar System excluding Pluto was established by the numerical computation of the maximum Lyapunov exponent
Geography of the rotational resonances and their stability in the ellipsoidal full two body problem
Abstract A fourth-order Hamiltonian describing the planar full two body problem is obtained, allowing for a mapping out of the geography of spin–spin–orbit resonances. The expansion of the mutual
Chaotic rotation of Hyperion?
Saturn's satellite Hyperion has been predicted to be in a chaotic rotation state as a result of its irregular shape and tidal interactions1. However, an analysis of Voyager 2 images by Thomas et al.2
Spin-orbit coupling and chaotic rotation for circumbinary bodies. Application to the small satellites of the Pluto-Charon system
We investigate the resonant rotation of circumbinary bodies in planar quasi-circular orbits. Denoting $n_b$ and $n$ the orbital mean motion of the inner binary and of the circumbinary body,
Spin dynamics of close-in planets exhibiting large transit timing variations
We study the spin evolution of close-in planets in compact multi-planetary systems. The rotation period of these planets is often assumed to be synchronous with the orbital period due to tidal
Frequency Map and Global Dynamics in the Solar System I
Abstract Frequency map analysis (FMA) is a refined numerical method based on Fourier techniques that provides a clear representation of the global dynamics of multidimensional systems, which is very
On the dynamical stability of the Rosetta orbiter. I.
In an orbit around a comet, a spacecraft is subject to several spin-orbit resonances. These enhanced couplings, induced by the rotation of the nucleus, by temporal variations in the outgassing
Frequency analysis for multi-dimensional systems: global dynamics and diffusion
Abstract Frequency analysis is a new method for analyzing the stability of orbits in a conservative dynamical system. It was first devised in order to study the stability of the solar system [J.
Tidal Evolution of Exoplanets
Tidal effects arise from differential and inelastic deformation of a planet by a perturbing body. The continuous action of tides modify the rotation of the planet together with its orbit until an
