Earth-based Stellar Occultation Predictions for Jupiter, Saturn, Uranus, Neptune, Titan, and Triton: 2023-2050
Richard G. French, Damya Souami
In support of studies of decadal-timescale evolution of outer solar system atmospheres and ring systems, we present detailed Earth-based stellar occultation predictions for Jupiter…
Venus Life Finder Mission Study
Sara Seager, Janusz J. Petkowski, Christopher E. Carr +9
The Venus Life Finder Missions are a series of focused astrobiology mission concepts to search for habitability, signs of life, and life itself in the Venus atmosphere. While peopl…
Pluto's lower atmosphere and pressure evolution from ground-based stellar occultations, 1988-2016
E. Meza, B. Sicardy, M. Assafin +167
Context. Pluto's tenuous nitrogen (N2) atmosphere undergoes strong seasonal effects due to high obliquity and orbital eccentricity, and has been recently (July 2015) observed by th…
Weighing Uranus' moon Cressida with the ring
Robert O. Chancia, Matthew M. Hedman, Richard G. French
The ring is one of the narrow rings of Uranus, consisting of a dense core that is 1-2 km wide and a diffuse outer sheet spanning about 40 km. Its dense core lies just exterior…
How Janus' Orbital Swap Affects the Edge of Saturn's A Ring?
Maryame El Moutamid, Philip D. Nicholson, Richard G. French +6
We present a study of the behavior of Saturn's A ring outer edge, using images and occultation data obtained by the Cassini spacecraft over a period of 8 years from 2006 to 2014. M…
Observing Planetary Rings with JWST: Science Justification and Observation Requirements
Matthew S. Tiscareno, Mark R. Showalter, Richard G. French +10
The James Webb Space Telescope (JWST) will provide unprecedented opportunities to observe the rings and small satellites in our solar system, accomplishing three primary objectives…
The opposition and tilt effects of Saturn's rings from HST observations
Heikki Salo, Richard G. French
The two major factors contributing to the opposition brightening of Saturn's rings are i) the intrinsic brightening of particles due to coherent backscattering and/or shadow-hiding…
The 1998 November 14 Occultation of GSC 0622-00345 by Saturn. II. Stratospheric Thermal Profile, Power Spectrum, and Gravity Waves
Joseph Harrington, Richard G. French, Katia Matcheva
On 1998 November 14, Saturn and its rings occulted the star GSC 0622-00345. The occultation latitude was 55.5 degrees S. This paper analyzes the 2.3 μm light curve derived by Harri…
The 1998 November 14 Occultation of GSC 0622-00345 by Saturn. I. Techniques for Ground-Based Stellar Occultations
Joseph Harrington, Richard G. French
On 1998 November 14, Saturn and its rings occulted the star GSC 0622-00345. We observed atmospheric immersion with NSFCAM at the National Aeronautics and Space Administration's Inf…
A procedure to analyze nonlinear density waves in Saturn's rings using several occultation profiles
N. J. Rappaport, P. -Y. Longaretti, R. G. French +2
Cassini radio science experiments have provided multiple occultation optical depth profiles of Saturn's rings that can be used in combination to analyze density waves. This paper e…
The Architecture of the Cassini Division
M. M. Hedman, P. D. Nicholson, K. H. Baines +6
The Cassini Division in Saturn's rings contains a series of eight named gaps, three of which contain dense ringlets. Observations of stellar occultations by the Visual and Infrared…
