A new dynamical model for the Uranian satellites
Abstract We have developed a new dynamical model of the main Uranian satellites, based on numerical integration and fitted to astrometric observations. Old observations, as well as modern and Voyager observations have been included. This model has provided ephemerides that have already been used for predicting the mutual events during the PHE-URA ...

Mutual occultations and eclipses of the major Uranian satellites in 2006–2010
The 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.

A note on the possibility of subsurface oceans on the uranian satellites
Icarus, 2022Abstract We use an existing thermal evolution model to assess the plausibility of subsurface oceans on the moons of Uranus. We adopt a conservative approach neglecting tidal heating and find that Titania and Oberon could support a subsurface ocean to the present day if conductive heat loss through the ice shell is limited.

Orbital evolution of the main Uranian satellites
Since 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 ...

Newly processed global imaging and topographic mapping of Uranus's five major satellites reveal differences and similarities to mid-sized satellites at Saturn and Pluto. Three modes of internal heat redistribution are recognized. The broad similarity of Miranda's three oval resurfacing zones to those mapped on Enceladus and (subtly) on Dione are likely

Mutual events of the uranian satellites 2006–2010
Icarus, 2005Abstract The upcoming crossing of the Sun and the Earth through the equatorial plane of the planet Uranus presents an opportunity to observe mutual eclipses and occultations of the uranian satellites. We present predictions for 321 such events from 2006 to 2010. 230 of these events are “nominal” i.e. they are predicted to occur based on the currently

Post eclipse thermal response of Uranian satellites with SINFONI: a status report .
We 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.

Mutual Events in the Uranian satellite system in 2007
The 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,
