Gap-opening Planets Make Dust Rings Wider
The Astrophysical Journal, 2023 As one of the most commonly observed disk substructures, dust rings from high-resolution disk surveys appear to have different radial widths. Recent observations on PDS 70 and AB Aur reveal not only planets in the disk, but also the accompanying wide ...

A Recent Impact Origin of Saturn’s Rings and Mid-sized Moons
The Astrophysical Journal, 2023 We simulate the collision of precursor icy moons analogous to Dione and Rhea as a possible origin for Saturn’s remarkably young rings. Such an event could have been triggered a few hundred million years ago by resonant instabilities in a previous ...

Characterising exo-ringsystems around fast-rotating stars using the Rossiter-McLaughlin effect [PDF]
, 2017 Planetary rings produce a distinct shape distortion in transit lightcurves. However, to accurately model such lightcurves the observations need to cover the entire transit, especially ingress and egress, as well as an out-of-transit baseline.

ABOUT TEMPERATURE FIELDS AND CONDITIONS OF GASEOUS CONDENSATION OF NEBULAES IN THE PLANETARY VORTEX
Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2014 New exact solution of the spherically-axissymmetric Eiler's equations, called as planetary vortex, is applied to the problem of formation in planetary nebula germs of planets due to the condensation of gases in the areas of vortex instability which ...

Saturn's Seismic Rotation Revisited
The Planetary Science Journal, 2023 Normal mode seismology is a promising means of measuring rotation in gas giant interiors, and ring seismology presents a singular opportunity to do so at Saturn.

Saturn's Exploration Beyond Cassini-Huygens [PDF]
, 2009 For its beautiful rings, active atmosphere and mysterious magnetic field, Saturn is a fascinating planet. It also holds some of the keys to understanding the formation of our Solar System and the evolution of giant planets in general.

The Stellar Content of the Polar Rings in the Galaxies NGC 2685 and NGC 4650A [PDF]
, 2003 We present the results of stellar photometry of polar-ring galaxies NGC 2685 and NGC 4650A, using the archival data obtained with the Hubble Space Telescope's Wide Field Planetary Camera 2.

Non-radial Oscillations in Rotating Giant Planets with Solid Cores: Application to Saturn and its Rings [PDF]
, 2013 Recent observations have revealed evidence for the global oscillations of Jupiter and Saturn, which can potentially provide a new window into the interior structure of giant planets.
