Composition, structure and evolution of Uranian and Neptunian satellites [PDF]

open access: yes, 1984
Large uncertainties in the current estimated densities or all of these satellites prevent detailed modeling or predictions. Nevertheless, current evidence suggests that at least Titania and Oberon might have "anomalously" high densities (2-3 g cm^)-3))

Dynamique des satellites d'Uranus [PDF]

open access: yes, 2014
Uranus and its complex and unexpected system of moons are still today a mystery of the solar system. This thesis focuses on the dynamics of these natural satellites, and discusses their orbital and internal evolutions, in the future as in the past. These

Near-infrared spectrophotometry of the satellites and rings of Uranus

open access: yes, 1981
New spectrophotometry from 1.5 to 2.5 μm is reported for the Uranian satellites Titania, Oberon, and Umbriel. A spectrum of the rings of Uranus from 2.0 to 2.4 μm is also reported. No evidence is found for frost covering the surface of the ring material,

Uranian Equinoctial Observations

open access: yes, 2008
In December of 2007, the planet Uranus passed through its northern hemisphere spring equinox. The northernmost latitudes of the planet and regular satellites were exposed to sunlight for the first time in 42 years.

Orbital dynamics of the Uranian satellites based on Voyager data

open access: yes, 1987
The satellites of Uranus all have significant non-zero eccentricities and in the case of Miranda a significant inclination as well. The Voyager 2 encounter with Uranus in January 1986, provided more accurate estimates of the masses and sizes of the ...

The Irregular Satellites of Neptune: a window to the Young Solar System [PDF]

open access: yes, 2009
The origin of planetary rotation and obliquity is one of the fundamental questions of Cosmogony, and also has proven to be one of the most difficult to answer.

Tidal breakup and origin of the Uranian ring system

open access: yes, 1984
It is shown that a configuration of alternating rings and moonlets could be the natural outcome of an evolutionary history of Uranus starting from a simple initial condition.

Voyager radio occultation by the Uranian rings: Structure, dynamics, and particle sizes

open access: yes, 1990
Diffraction of Voyager 2's 3.6 and 13 cm wavelength microwaves by the Uranian rings is removed through an inverse Fresnel transform filtering procedure that accommodates the significant eccentricity of the rings. Resulting 50 m resolution profiles at two
