The linear stability of dilute particulate rings [PDF]
, 2006 Irregular structure in planetary rings is often attributed to the intrinsic instabilities of a homogeneous state undergoing Keplerian shear. Previously these have been analysed with simple hydrodynamic models. We instead employ a kinetic theory, in which

A Dust Halo from Saturn’s Main Rings Extending Several Saturnian Radii above the Ring Plane
The Planetary Science JournalDuring the Grand Finale orbits, the Cassini spacecraft orbited Saturn with high inclinations and perikrones near the ring plane crossings. The Cosmic Dust Analyzer sampled ice and mineral dust particles during these orbits.

Detecting transit signatures of exoplanetary rings using SOAP3.0 [PDF]
, 2017 CONTEXT. It is theoretically possible for rings to have formed around extrasolar planets in a similar way to that in which they formed around the giant planets in our solar system. However, no such rings have been detected to date. AIMS: We aim to test

The Yarkovsky Effect on the Long-term Evolution of Binary Asteroids
The Astrophysical Journal LettersWe explore the Yarkovsky effect on small binary asteroids. While significant attention has been given to the binary YORP effect, the Yarkovsky effect is often overlooked.

Simulating planet migration in globally evolving disks [PDF]
, 2006 Numerical simulations of planet-disk interactions are usually performed with hydro-codes that -- because they consider only an annulus of the disk, over a 2D grid -- can not take into account the global evolution of the disk.

JWST/MIRI Study of the Enigmatic Mid-infrared Rings in the Planetary Nebula NGC 1514
The Astronomical JournalWhile NGC 1514 is an elliptical, but complex, planetary nebula at optical wavelengths, it was discovered to have a pair of infrared-bright, axisymmetric rings contained within its faint outer shell during the course of the Wide-field Infrared Survey ...

Phase-Space Volume of Regions of Trapped Motion: Multiple Ring Components and Arcs
, 2008 The phase--space volume of regions of regular or trapped motion, for bounded or scattering systems with two degrees of freedom respectively, displays universal properties. In particular, sudden reductions in the phase-space volume or gaps are observed at
