Measurements of rotation rates and gravitational harmonics of Neptune made with the Voyager 2 spacecraft allow tighter constraints on models of the planet's interior. Shock measurements of material that may match the composition of Neptune, the so-calied planetary ``ice,'' have been carried out to pressures exceeding 200 gigapascals (2 megabars). Comparison of shock data with inferred pressure-density profiles for both Uranus and Neptune shows substantial similarity through most of the mass of… 
Interior Models of Uranus and Neptune
"Empirical" models (pressure versus density) of Uranus and Neptune interiors constrained by the gravitational coefficients J 2, J 4, the planetary radii and masses, and Voyager solid-body rotation
Uranus and Neptune: Shape and rotation
Monte Carlo interior models for Uranus and Neptune
To explore a greater realm of model phase space than has previously been mapped, we generate randomly chosen interior models for Uranus and Neptune. The models are constrained by the observed mass,
Uranus and Neptune: Origin, Evolution and Internal Structure
There are still many open questions regarding the nature of Uranus and Neptune, the outermost planets in the Solar System. In this review we summarize the current-knowledge about Uranus and Neptune
Chemical processes in the deep interior of Uranus.
An experimental and computational study of the physical properties of a fluid representative of the interior of Uranus and Neptune, and electrical conductivity results confirm that the core cannot be well mixed if it is to generate non-axisymmetric magnetic fields.
Uranus and Neptune interior models
This paper is concerned with the interior structure of Uranus and Neptune. Our approach is three-fold. First, a set of three-layer models for both Uranus and Neptune are constructed using a method
Planetary science: Plumbing the depths of Uranus and Neptune
It is calculated that the winds on Uranus and Neptune are confined to a thin 'weather layer' no more than 1,000 km deep, which implies that the dynamics controlling these winds derive from come from shallow processes rather than deep atmospheric circulation.
The interiors of Uranus and Neptune: current understanding and open questions
This review focuses on the things the authors do not know about the interiors of Uranus and Neptune with a focus on why the planets may be different, rather than the same.
Gravitational signature of Jupiter's internal dynamics
Telescopic observations and space missions to Jupiter have provided vast information about Jupiter's cloud level winds, but the depth to which these winds penetrate has remained an ongoing mystery.


Post Voyager comparisons of the interiors of Uranus and Neptune
The recent Voyager flyby of Uranus and Neptune has provided refined values for the gravitational moments and rotation periods of those planets. Using these new parameters, models of the interiors of
High Winds of Neptune: A Possible Mechanism
In this model, the rapid retrograde winds observed are a manifestation of deep convection, and the high efficiency of the planet's heat engine is intrinsic from the room allowed at low latitudes for reversible processes, the high temperatures at which heat is added to the atmosphere and the low temperatures atWhich heat is extracted.
The Nature of the Interior of Uranus Based on Studies of Planetary Ices at High Dynamic Pressure
To interpret the origin of the magnetic field, measurements were made of electrical conductivity and equation-of-state data of the planetary "ices" ammonia, methane, and "synthetic Uranus at shock pressures and temperatures up to 75 gigapascals and 5000 K.
Shock temperature measurements of planetary ices: NH3, CH4, and ‘‘synthetic Uranus’’
Shock temperature measurements have been performed on several materials which have relevance to the modeling of the outer planets. These materials are methane, ammonia and a mixture of water,
Orbits of the six new satellites of Neptune
Orbital elements are presented for the six small satellites of Neptune, 1989N1 through 1989N6, discovered by Voyager 2. Details of the image and orbit analyses are examined. The solution for the
Occultation detection of a neptunian ring-like arc
The apparent closest approach of the star SAO186001 to Neptune was observed photoelectrically on 22 July 1984 at Cerro Tololo Inter-American Observatory. A 32% signal drop lasting about 1.2 s was
