Abstract New Horizons mission observations show that the small satellites Styx, Nix, Kerberos and Hydra, of the Pluto–Charon system, have not tidally spun-down to near synchronous spin states and have high obliquities with respect to their orbit about the Pluto–Charon binary (Weaver, 2016). We use a damped mass-spring model within an N-body simulation to study spin and obliquity evolution for single spinning non-round bodies in circumbinary orbit. Simulations with tidal dissipation alone do not… 
The future large obliquity of Jupiter
Aims. We aim to determine whether Jupiter’s obliquity is bound to remain exceptionally small in the Solar System, or if it could grow in the future and reach values comparable to those of the other
On the Early In Situ Formation of Pluto's Small Satellites
The formation of Pluto's small satellites - Styx, Nix, Keberos and Hydra - remains a mystery. Their orbits are nearly circular and are near mean-motion resonances and nearly coplanar with Charon's
Tilting Styx and Nix but not Uranus with a Spin-Precession-Mean-motion resonance
TLDR
A Hamiltonian model is constructed for the spin axis of a planet perturbed by a nearby planet with both planets in orbit about a star and explains how Styx and Nix can be tilted to high obliquity via outward migration of Charon.
The Pluto System After New Horizons
The New Horizons (NH) flyby of the Pluto–Charon binary planet and its system of four small surrounding satellites in mid-2015 revolutionized our knowledge of this distant planet and its moons. Beyond
A Pluto–Charon Sonata: Dynamical Limits on the Masses of the Small Satellites
During 2005-2012, images from Hubble Space Telescope (HST) revealed four moons orbiting Pluto-Charon (Weaver et al 2006, Showalter et al 2011, 2012). Although their orbits and geometric shapes are
On the Origin of the Pluto System
For six decades following its discovery, Pluto was the only known Sun-orbiting world in the dynamical vicinity of Neptune. An early origin concept postulated that Neptune originally had two large
Chaotic Dynamics in the Planar Gravitational Many-Body Problem with Rigid Body Rotations
TLDR
It is shown that the extent of chaos in parameter space is strongly tied to the deviations from a purely circular orbit, and the existence of homoclinic chaos in the case where one of the orbits is nearly circular by way of the Melnikov method is analytically demonstrated.
Excitation of Tumbling in Phobos and Deimos.
TLDR
Mass-spring model simulations are used to investigate past spin states of a viscoelastic Phobos and Deimos and show that these moons can remain so for an extended period and during this time their orbital eccentricity can be substantially reduced.
2 Soft-astronomy : Spin dynamics using viscoelastic mass-spring model simulations
In 2006 I worked on general theory on orbital resonance capture [1] to cover the non-adiabatic regime, extending Peter Goldreich and Nicole Borderie’s work that was restricted to adiabatic drift
Near/Far Side Asymmetry in the Tidally Heated Moon.
TLDR
A heat conductivity model illustrates that a moderately asymmetric and growing lunar crust could maintain its near/far side thickness asymmetry but only while the Moon is near the Earth.

Abstract The orbits of Pluto’s four small satellites (Styx, Nix, Kerberos, and Hydra) are nearly circular and coplanar with the orbit of the large satellite Charon, with orbital periods nearly in the

Motivated by the New Horizons mission, we consider how Pluto's small satellites—currently Styx, Nix, Kerberos, and Hydra—grow in debris from the giant impact that forms the Pluto-Charon binary. After

Synchronous Locking of Tidally Evolving Satellites
Abstract Satellite spin states evolve under the action of solid body torques and tidal forces. The tidal effects result in a damping of fast spin rates and, ultimately, in the locking of the spin
Resonant interactions and chaotic rotation of Pluto’s small moons
TLDR
It is reported that Styx, Nix and Hydra are tied together by a three-body resonance, which is reminiscent of the Laplace resonance linking Jupiter’s moons Io, Europa and Ganymede.

TLDR
The New Horizons results on Pluto’s small moons help to elucidate the conditions under which the Pluto system formed and evolved, and massively increase the understanding of the bodies in the outer solar system.
