Voyager 2 Radio Science Observations of the Uranian System: Atmosphere, Rings, and Satellites
Science, 1986Voyager 2 radio occultation measurements of the Uranian atmosphere were obtained between 2 and 7 degrees south latitude. Initial atmospheric temperature profiles extend from pressures of 10 to 900 millibars over a height range of about 100 kilometers.

Mutual occultations and eclipses of the major Uranian satellites in 2006–2010
Solar System Research, 2006The upcoming epoch of rare events—that of mutual occultations and eclipses in the system of the major Uranian satellites—is reported. Such epochs last for four years and occur every 43 years. The ephemerides and circumstances for the events occurring during the 2006–2010 epoch are computed.

Photometry from Voyager 2: Initial Results from the Uranian Atmosphere, Satellites, and Rings
Science, 1986The Voyager 2 photopolarimeter successfully completed the Uranus encounter, acquiring new data on the planet's atmosphere, its principal satellites, and its ring system. Spatially resolved photometry of the atmosphere at 0.27 micrometer shows no enhancement in absorption toward the pole, unlike the case for Jupiter and Saturn.

The Uranian satellites and hyperion: New spectrophotometry and compositional implications
Icarus, 1983New reflectance spectra at 3.5 percent resolution have been obtained for Ariel, Titania, Oberon, and Hyperion in the 0.8 to 1.6-micron spectrum region. The new spectra show no absorptions other than the 1.5 micron water-ice feature (within the precision of the data), and demonstrate extension into the 0.8- to 1.6 micron region of the 1.5- to 2.5 micron

Orbital evolution of the main Uranian satellites
2011Since Voyager 2 space mission, we know some properties of the main Uranian satellites (Miranda, Ariel, Umbriel, Titania, Oberon): on the one hand, we observe an important resurfacing of both Miranda and Ariel, and on the other hand some strangenesses in the orbital elements such as the anomalously high inclinaison of Miranda or the anomalously high ...

Cratering history of the Uranian satellites: Umbriel, Titania, and Oberon
Journal of Geophysical Research: Space Physics, 1987Crater size‐frequency data for Umbriel, Titania, and Oberon are presented, and the implications of those data are discussed in terms of the geologic histories of these bodies and the populations of objects that have cratered them. The surfaces of Oberon and Umbriel are old and are inferred to date to a period early in their histories when the cratering

Mutual Events in the Uranian satellite system in 2007
2008The equinox time on the giant planets When the Sun crosses the equatorial plane of a giant planet, it is the equinox time occurring every half orbit of the planet, i.e. every 6 years for Jupiter, 14 years for Saturn, 42 years for Uranus and 82 years for Neptune. Except Neptune, each planet have several major satellites orbiting in the equatorial plane,

Post eclipse thermal response of Uranian satellites with SINFONI: a status report .
Memorie della Società Astronomica Italiana. Supplementi, 2008We report on the status of a project to measure eclipse-induced changes in surface temperature on the major Uranian satellites. Such measurements enable a uniquely direct determination of the thermal inertia, a measure of the resistance to changes in surface temperature.
