We present BVR photometric colors of six Uranian and two Neptunian irregular satellites, collected using the Magellan Observatory (Las Campanas, Chile) and the Keck Observatory (Manua Kea, Hawaii). The colors range from neutral to light red, and like the Jovian and the Saturnian irregular satellites (Grav et al.) there is an apparent lack of the extremely red objects found among the Centaurs and Kuiper Belt objects. The Uranian irregular satellites can be divided into three possible dynamical… Expand

Properties of the irregular satellite system around Uranus inferred from K2, Herschel and Spitzer observations
In this paper we present visible range light curves of the irregular Uranian satellites Sycorax, Caliban, Prospero, Ferdinand and Setebos taken with Kepler Space Telescope in the course of the K2Expand
Colors and Shapes of the Irregular Planetary Satellites
It is widely recognized that the irregular satellites of the giant planets were captured from initially heliocentric orbits. However, the mechanism of capture and the source region from which theyExpand
Light curves and colours of the faint Uranian irregular satellites Sycorax, Prospero, Stephano, Setebos, and Trinculo
Context. After the work of Gladman et al. (1998, Nature, 392, 897), it is now assessed that many irregular satellites are orbiting around Uranus. Aims. Despite many studies performed in past years,Expand
The Irregular Satellites: The Most Collisionally Evolved Populations in the Solar System
The known irregular satellites of the giant planets are dormant comet-like objects that reside on stable prograde and retrograde orbits in a realm where planetary perturbations are only slightlyExpand
Irregular Satellites of the Giant Planets
The irregular satellites of the outer planets, whose population now numbers over 100, are likely to have been captured from heliocentric orbit during the early period of solar system history. TheyExpand
Discovery of five irregular moons of Neptune
The discovery of five exceedingly faint moons of Neptune, two with prograde and three with retrograde orbits, which were presumably captured by Neptune. Expand
Red material on the large moons of Uranus: Dust from the irregular satellites?
Abstract The large and tidally-locked “classical” moons of Uranus display longitudinal and planetocentric trends in their surface compositions. Spectrally red material has been detected primarily onExpand
Constraints to Uranus' Great Collision. IV. The Origin of Prospero
Context. It is widely accepted that the large obliquity of Uranus is the result of a great tangential collision (GC) with an Earth size proto-planet at the end of the accretion process. The impulseExpand
The science case for an orbital mission to Uranus: exploring the origins and evolution of ice giant planets
Giant planets helped to shape the conditions we see in the Solar System today and they account for more than 99% of the mass of the Sun's planetary system. They can be subdivided into the Ice GiantsExpand
NEOWISE: Observations of the Irregular Satellites of Jupiter and Saturn
We present thermal model fits for 11 Jovian and 3 Saturnian irregular satellites based on measurements from the WISE/NEOWISE data set. Our fits confirm spacecraft-measured diameters for the objectsExpand


Photometric survey of the irregular satellites
Abstract We present BVRI colors of 13 jovian and 8 saturnian irregular satellites obtained with the 2.56 m Nordic Optical Telescope on La Palma, the 6.5 m Magellan Baade Telescope on La Campanas, andExpand
Near-Infrared Photometry of the Irregular Satellites of Jupiter and Saturn
We present JHKs photometry of 10 Jovian and four Saturnian irregular satellites, taken with the Near-InfraRed Imager at the 8 m Gemini North Observatory on Mauna Kea, Hawaii. The observed objectsExpand
Photometric and spectroscopic observations of Sycorax, satellite of Uranus
Sycorax is the brightest of the ve irregular Uranian satellites recently discovered. These satellites are supposed to be captured bodies. We present visible and near-infrared photometry, as well asExpand
Comprehensive Photometry of the Rings and 16 Satellites of Uranus with the Hubble Space Telescope
Abstract Photometric properties of 4 rings and 16 satellites of Uranus are presented, based on 41 Hubble Space Telescope images taken in 1997. Up to 25 filters per object covered the wavelength rangeExpand

Color Patterns in the Kuiper Belt: A Possible Primordial Origin
As a result of our continuing photometric survey, we report here optical colors for 36 Kuiper Belt objects, increasing our sample size to 91 objects. We find that certain dynamical classes of objectsExpand
Orbital and Collisional Evolution of the Irregular Satellites
The irregular moons of the Jovian planets are a puzzling part of the solar system inventory. Unlike regular satellites, the irregular moons revolve around planets at large distances in tilted andExpand
Discovery of 12 satellites of Saturn exhibiting orbital clustering
The discovery of 12 irregular satellites of Saturn is reported, along with the determinations of their orbits, indicating that most of the irregular moons are collisional remnants of larger satellites that were fragmented after capture, rather than being captured independently. Expand
Comparative global albedo and color maps of the Uranian satellites
Abstract The large Uranian satellites comprise a unique class of dark, grayish objects. They exhibit important differences in albedo and color among each other and on their individual surfaces.Expand
Nereid Has Complex Large-Amplitude Photometric Variability
Abstract We report on 224 photometric measurements of Nereid, a small outer satellite of Neptune with a 360-day orbit of high eccentricity (0.751). Our photometry covers 64 nights from 1987 to 1997Expand
