The Voyager 2 encounter with the Neptune system included radio science investigations of the masses and densities of Neptune and Triton, the low-order gravitational harmonics of Neptune, the vertical structures of the atmospheres and ionospheres of Neptune and Triton, the composition of the atmosphere of Neptune, and characteristics of ring material. Demanding experimental requirements were met successfully, and study of the large store of collected data has begun. The initial search of the… 
Voyager 2 at Neptune: Imaging Science Results
Voyager 2 images of Neptune reveal a windy planet characterized by bright clouds of methane ice suspended in an exceptionally clear atmosphere above a lower deck of hydrogen sulfide or ammonia ices.
The New Horizons Radio Science Experiment (REX)
The New Horizons (NH) Radio Science Experiment, REX, is designed to determine the atmospheric state at the surface of Pluto and in the lowest few scale heights. Expected absolute accuracies in n, p,
Particles and fields measurements at Neptune with Voyager 2
Abstract The particles and fields complement of instruments on the Voyager 2 spacecraft performed a comprehensive set of measurements during the encounter with the Neptune system on August 24 through
The atmosphere of Neptune: Results of radio occultation measurements with the Voyager 2 spacecraft
Radio tracking data acquired during Voyager 2's occultation by Neptune have been used to study the thermal structure and composition of Neptune's troposphere and stratosphere. The occultation began
Plasma Observations Near Neptune: Initial Results from Voyager 2
TLDR
The plasma science experiment on Voyager 2 made observations of the plasma environment in Neptune's magnetosphere and in the surrounding solar wind, finding the maximum plasma density observed in the magnetosphere is inferred to be 1.4 per cubic centimeter, the smallest observed by Voyager in any magnetosphere.
Design of a low cost mission to the Neptunian system
Visited only by Voyager 2 in 1989, Neptune and its moon Triton hold important clues to the formation and evolution of the solar system and exoplanetary systems. Neptune-sized planets are the most
Voyager 2 electron observations in the magnetosphere of Neptune
This paper describes electron data obtained during the Neptune encounter by the Voyager 2 plasma science experiment. The densities and temperatures of low-energy (10-5950 eV) electrons and the
Ultraviolet Spectrometer Observations of Neptune and Triton
Results from the occultation of the sun by Neptune imply a temperature of 750 � 150 kelvins in the upper levels of the atmosphere (composed mostly of atomic and molecular hydrogen) and define the
Temperature and Thermal Emissivity of the Surface of Neptune's Satellite Triton
Analysis of the preliminary results from the Voyager mission to the Neptune system has provided the scientific community with several methods by which the temperature of Neptune's satellite Triton
Triton, Pluto, Centaurs, and Trans-Neptunian Bodies
The diverse populations of icy bodies of the outer Solar System (OSS) give critical information on the composition and structure of the solar nebula and the early phases of planet formation. The two

Voyager 2 radio signals were observed essentially continuously during a grazing occultation of the spacecraft by the southern limb of Jupiter. Intensity data show a classic atmospheric occultation

Radio science investigations of the saturn system with voyager 1: preliminary results.
TLDR
Radio occultation measurements of Titan's equatorial atmosphere successfully probed to the surface and indicated that molecular nitrogen is the predominant atmospheric constituent, while preliminary analysis of the radio tracking data yields new values for the masses of Rhea and Titan.
The atmosphere of Uranus: Results of radio occultation measurements with Voyager 2
During Voyager 2's occultation by Uranus the radio link from the spacecraft probed the atmosphere of the planet at latitudes ranging from 2° to 7° south. The measurements, which were conducted at two
Submillimeter and millimeter observations of Uranus and Neptune
We have made narrowband photometric measurements of Uranus and Neptune covering the wavelength range from 0.35 to 3.3 mm. The observations provide accurate comparative radiometry of these planets.

Radio Science with Voyager 2 at Saturn: Atmosphere and Ionosphere and the Masses of Mimas, Tethys, and Iapetus
TLDR
Radio occultation measurements of Saturn's atmosphere suggest the opposite trend, in which the intermediate-sized satellites of Saturn may represent several classes of objects that differ with respect to the relative amounts of water, ammonia, and methane ices incorporated at different temperatures during formation.
