Neptune's capture of its moon Triton in a binary–planet gravitational encounter
It is reported that a three-body gravitational encounter between a binary system (of ∼103-kilometre-sized bodies) and Neptune is a far more likely explanation for Triton's capture.
Production of intermediate-mass black holes in globular clusters
The discovery of numerous non-nuclear X-ray point sources with luminosities L>1039 erg s−1 in several starburst galaxies has stimulated speculation about their nature and origin. The strong…
Tilting Saturn. I. Analytic Model
The tilt of Saturn's spin axis to its orbit plane is 26.°7, while that of Jupiter is only 3.°1. We offer an explanation for this puzzling difference owing to gravitational perturbations of Saturn by…
The Pluto system: Initial results from its exploration by New Horizons
The New Horizons encounter revealed that Pluto displays a surprisingly wide variety of geological landforms, including those resulting from glaciological and surface-atmosphere interactions as well as impact, tectonic, possible cryovolcanic, and mass-wasting processes.
Orbital resonances in the inner neptunian system. II. Resonant history of Proteus, Larissa, Galatea, and Despina
Resonant interactions and chaotic rotation of Pluto’s small moons
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.
Plasma, plumes and rings: Saturn system dynamics as recorded in global color patterns on its midsize icy satellites
Circumplanetary Dust Dynamics: Effects of Solar Gravity, Radiation Pressure, Planetary Oblateness, and Electromagnetism
Abstract We consider the motions of circumplanetary objects perturbed simultaneously by solar gravity, radiation pressure, planetary oblateness, and electromagnetic forces. Confining ourselves to the…
The small satellites of Pluto as observed by New Horizons
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.
Four-Body Effects in Globular Cluster Black Hole Coalescence
In the high-density cores of globular clusters, multibody interactions are expected to be common, with the result that black holes in binaries are hardened by interactions. It was shown by Sigurdsson…
