Theory and Modeling of Large Scale Plasmapause Surface Waves
Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.Abstract The plasmapause in Earth's magnetosphere represents the boundary between the plasma which co‐rotates with the Earth (plasmasphere), and the more tenuous plasmatrough outside. The density change across the plasmapause can be large, changing by approximately 1–2 orders of magnitude depending on the prevailing conditions. This would suggest it to

THE POPULATION OF PROPELLERS IN SATURN'S A RING [PDF]
The Astronomical Journal, 2008 We present an extensive data set of ~150 localized features from Cassini images of Saturn's Ring A, a third of which are demonstrated to be persistent by their appearance in multiple images, and half of which are resolved well enough to reveal a characteristic "propeller" shape.

Injections of Multi‐MeV Electrons in the Magnetosphere of Jupiter
Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.Abstract Energetic particle injections provide a means for fast inward radial transport and adiabatic acceleration of electrons in the magnetosphere of Jupiter. Furthermore, enhanced whistler‐mode wave activity during injections can further accelerate electrons to MeV energy.

Detecting Planetary Oblateness in the Era of JWST: A Case Study of Kepler-167e
The Astronomical JournalPlanets may be rotationally flattened, and their oblateness thus provides useful information on their formation and evolution. Here, we develop a new algorithm that can compute the transit light curve due to an oblate planet very efficiently and use it ...

Enceladus Water Plume Modeling Using DSMC
Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.Abstract This study investigates the water plumes of Saturn's moon, Enceladus, using Direct Simulation Monte Carlo (DSMC) modeling to analyze venting dynamics and plume structures. Building on prior research, we employ a parametrized DSMC approach to model water vapor and ice particle flows, leveraging Cassini spacecraft data from instruments such as ...

Seismology of Giant Planets: General Overview and Results from the Kepler K2 Observations of Neptune
EPJ Web of Conferences, 2017 For this invited contribution, I was asked to give an overview about the application of helio and aster-oseismic techniques to study the interior of giant planets, and to specifically present the recent observations of Neptune by Kepler K2.

Impact of Saturn's rings on mission analysis for MJS 77 [PDF]
Mariner Jupiter-Saturn '77 mission objectives for Saturn are considered which affect the trajectory design and in particular the aim point at Saturn. These objectives include the following: (1) earth, sun occulation of Saturn, rings, and satellites; (2 ...

The Rings of Saturn and Uranus [PDF]
Symposium - International Astronomical Union, 1979 Nature has presented us with two systems of planetary rings. They are not at all similar. Saturn has bright, broad rings separated by narrow gaps. The rings of Uranus are dark, narrow and widely spaced. Presumably both sets of rings lie inside the Roche limit and this is why the ring material has not condensed into satellites.
