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, and the 6.5 m MMT on Mt. Hopkins. The observations were performed from December 2001 to March 2002. The colors of the irregular satellites vary from grey to light red. We have arbitrarily divided the known irregular satellites into two classes based on their colors. One, the grey color class, has… Expand

A deeper look at the colors of the saturnian irregular satellites
Abstract We have performed broadband color photometry of the twelve brightest irregular satellites of Saturn with the goal of understanding their surface composition, as well as their physicalExpand
Photometry of Irregular Satellites of Uranus and Neptune
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).Expand
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
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
Studies of irregular satellites: I. Lightcurves and rotation periods of 25 Saturnian moons from Cassini observations
Abstract Disk-integrated time-resolved photometric observations have been performed for 25 irregular moons of Saturn with the ISS camera of the Cassini spacecraft in a wide range of solar phaseExpand
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
Composition of Jupiter irregular satellites sheds light on their origin
Irregular satellites of Jupiter with their highly eccentric, inclined and distant orbits suggest that their capture took place just before the giant planet migration. We aim to improve ourExpand
Colors of Centaurs
Minor planets on outer planet-crossing orbits, called Centaur objects, are important members of the solar system in that they dynamically link Kuiper belt objects to Jupiter-family comets. InExpand
The discovery of faint irregular satellites of Uranus
We report the discovery of four new uranian irregular satellites in our deep, mR ∼ 25.4, optical search around that planet. The orbital properties of these satellites are diverse. Th ere is someExpand
Estimates of the physical parameters of remote planetary satellites
Since 1998, 97 new remote satellites of Jupiter, Saturn, Uranus, and Neptune have been discovered. Since their brightness is rather weak, it is difficult to perform their photometry and determineExpand


The Color Distribution in the Edgeworth-Kuiper Belt*
In 1997 we began the Meudon Multicolor Survey of Outer Solar System Objects with the aim of collecting a large and homogeneous set of color data for trans-Neptunian objects (TNOs) and Centaurs. HereExpand
Colors and Spectra of Kuiper Belt Objects
We present new measurements of the optical colors of Kuiper belt objects, principally from the Keck 10 m telescope. The measurements confirm the existence of a wide spread in the B-V, V-R, and R-IExpand
Implied Evolutionary Differences of the Jovian Irregular Satellites from a BVR Color Survey
Abstract We present BVR colors and magnitudes for four jovian irregular prograde satellites (Himalia J6, Elara J7, Lysithea J10, and Leda J13) and four irregular retrograde satellites (Pasiphae J8,Expand
Near-Infrared Observations of the Outer Jovian Satellites
Abstract On September 21, 1998, the outer jovian satellites Himalia (J6), Elara (J7), Carme (J11), Pasiphae (J8), and Sinope (J9) were detected in the J , H , and K s bandpasses in the course of theExpand
Photometric properties of outer planetary satellites
Abstract We present optical broadband photometry for the satellites J6, J7, J8, S7, S9, U3, U4, N1, and polarimetry for J6, obtained between 1970 and 1979. The outer Jovian satellites resemble CExpand
Two distinct populations of Kuiper-belt objects

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
Extremely red Kuiper-belt objects in near-circular orbits beyond 40  AU
It is reported that all nine of the KBOs in this survey on near-circular (low-eccentricity) orbits with perihelion distances larger than 40 AU have extremely red surfaces, thereby connecting an observable property with a dynamical class. Expand

Spectrophotometric Observations of Edgeworth–Kuiper Belt Objects
Abstract The Edgeworth–Kuiper Belt (EKB) objects are fossil remnants of the formation of the Solar System and they represent an important reservoir of primordial, thermally unprocessed material. TheExpand
