Saturn's Magnetic Field at Unprecedented Detail Achieved by Cassini's Close Encounters
Hao Cao, Michele K. Dougherty, Gregory J. Hunt +4
The last 22.5 orbits of the Cassini mission brought the spacecraft to less than 3000 km from Saturn's 1-bar surface. These close encounters offered an unprecedented view of Saturn'…
A Global Simulation of the Dynamo, Zonal Jets, and Vortices on Saturn
Rakesh Kumar Yadav, Hao Cao, Jeremy Bloxham
The fluid dynamics in planet Saturn gives rise to alternating east-west jet streams, large cyclonic and anticyclonic vortices, and a dipole-dominant magnetic field which is highly…
A dynamo simulation generating Saturn-like small magnetic dipole tilts
Rakesh K. Yadav, Hao Cao, Jeremy Bloxham
Among planetary dynamos, the magnetic field of Saturn stands out in its exceptional level of axisymmetry. One of its peculiar features is that the magnetic dipole mode is tilted wi…
Investigating Barotropic Zonal Flow in Jupiter's Deep Atmosphere using Juno Gravitational Data
Laura Kulowski, Hao Cao, Rakesh K. Yadav +1
The high-precision Juno gravitational measurements allow us to infer the structure of Jupiter's deep atmospheric zonal flow. Since this inference is nonunique, it is important to e…
The Saturn Ring Skimmer Mission Concept: The next step to explore Saturn's rings, atmosphere, interior, and inner magnetosphere
Matthew S. Tiscareno, Mar Vaquero, Matthew M. Hedman +21
The innovative Saturn Ring Skimmer mission concept enables a wide range of investigations that address fundamental questions about Saturn and its rings, as well as giant planets an…
The landscape of Saturn's internal magnetic field from the Cassini Grand Finale
Hao Cao, Michele K. Dougherty, Gregory J. Hunt +4
The Cassini mission entered the Grand Finale phase in April 2017 and executed 22.5 highly inclined, close-in orbits around Saturn before diving into the planet on September 15th 20…
Growth Model Interpretation of Planet Size Distribution
Li Zeng, Stein B. Jacobsen, Dimitar D. Sasselov +13
The radii and orbital periods of 4000+ confirmed/candidate exoplanets have been precisely measured by the Kepler mission. The radii show a bimodal distribution, with two peaks corr…
Solar System Ice Giants: Exoplanets in our Backyard
Abigail Rymer, Kathleen Mandt, Dana Hurley +110
Future remote sensing of exoplanets will be enhanced by a thorough investigation of our solar system Ice Giants (Neptune-size planets). What can the configuration of the magnetic f…
Zonal Flow Magnetic Field Interaction in the Semi-Conducting Region of Giant Planets
Hao Cao, David J. Stevenson
All four giant planets in the Solar System feature zonal flows on the order of 100 m/s in the cloud deck, and large-scale intrinsic magnetic fields on the order of 1 Gauss near the…
Gravity and Zonal Flows of Giant Planets: From the Euler Equation to the Thermal Wind Equation
Hao Cao, David J. Stevenson
Any nonspherical distribution of density inside planets and stars gives rise to a non-spherical external gravity and change of shape. If part or all of the observed zonal flows at…
Solar LImb Prominence CAtcher and Tracker (SLIPCAT): An Automated System and Its Preliminary Statistical Results
Yuming Wang, Hao Cao, Junhong Chen +6
In this paper, we present an automated system, which has the capability to catch and track solar limb prominences based on observations from EUV 304 passband. The characteristic pa…
