Uranus [PDF]

Proceedings of the 15th ACM Asia Conference on Computer and Communications Security, 2020
Applications written in Java have strengths to tackle diverse threats in public clouds, but these applications are still prone to privileged attacks when processing plaintext data. Intel SGX is powerful to tackle these attacks, and traditional SGX systems rewrite a Java application's sensitive functions, which process plaintext data, using C/C++ SGX ...

The Case for a New Frontiers–Class Uranus Orbiter: System Science at an Underexplored and Unique World with a Mid-scale Mission

The Planetary Science Journal, 2022
Current knowledge of the Uranian system is limited to observations from the flyby of Voyager 2 and limited remote observations. However, Uranus remains a highly compelling scientific target due to the unique properties of many aspects of the planet ...

The Orbits of Uranus, Its Satellites and Rings, the Gravity Field of the Uranian System, and the Orientation of the Poles of Uranus and Its Satellites

The Astronomical Journal
R. A. Jacobson determined the orbits of the Uranian satellites, the masses of Uranus and its satellites, and the orientation of the pole of Uranus from Earth-based astrometry, Earth-based ring occultations, and observations acquired with the Voyager 2 ...

Thermodynamics of diamond formation from hydrocarbon mixtures in planets [PDF]

Nature Communications, 2023
This study combines computational chemistry and machine learning to provide insight on whether diamonds can form inside ice giants. This can help explain the dichotomy of Uranus and Neptune.

Does Uranus' Asymmetric Magnetic Field Produce a Relatively Weak Proton Radiation Belt?

Geophysical Research Letters, 2022
Since the Voyager 2 flyby in 1986 the radiation belts of Uranus have presented a problem for physicists. The observations indicate the electron radiation belt is far more intense than the proton radiation belt, and while the electron intensities are ...

Phase separation of planetary ices explains nondipolar magnetic fields of Uranus and Neptune. [PDF]

Proc Natl Acad Sci U S A
Significance The Voyager spacecraft measured that Uranus and Neptune have nondipolar magnetic fields while strong dipole fields had been expected. Stanley and Bloxham thus proposed that the magnetic fields be generated only in a thin outer layer.

The anomalous state of Uranus's magnetosphere during the Voyager 2 flyby. [PDF]

Nat Astron
The Voyager 2 flyby of Uranus in 1986 revealed an unusually oblique and off-centred magnetic field. This single in situ measurement has been the basis of our interpretation of Uranus’s magnetosphere as the canonical extreme magnetosphere of the solar ...

From Methane to Nanodiamond Precursors in Water: Superacid-like Condensation Pathways Under Extreme Conditions. [PDF]

Angew Chem Int Ed Engl
Under extreme pressure and temperature, superionic water acts as a strong superacid, catalyzing methane polycondensation through pentacoordinated carbonium ions (CH5+). This discovery reveals the non‐classical carbocation chemistry underlying the early stages of diamond formation in water under extreme conditions.

Compositions and Interior Structures of the Large Moons of Uranus and Implications for Future Spacecraft Observations. [PDF]

J Geophys Res Planets, 2023
The five large moons of Uranus are important targets for future spacecraft missions. To motivate and inform the exploration of these moons, we model their internal evolution, present‐day physical structures, and geochemical and geophysical signatures ...

One EURO for Uranus: the Elliptical Uranian Relativity Orbiter mission [PDF]

Monthly notices of the Royal Astronomical Society, 2023
Recent years have seen increasing interest in sending a mission to Uranus, visited so far only by Voyager 2 in 1986. EURO (Elliptical Uranian Relativity Orbiter) is a preliminary mission concept investigating the possibility of dynamically measuring ...
