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 physical relationship. We find that the satellites have a wide variety of different surface colors, from the negative spectral slopes of the two retrograde satellites S IX Phoebe ( S ′ = − 2.5 ± 0.4 ) and S XXV Mundilfari ( S ′ = − 5.0 ± 1.9 ) to the fairly red slope of S XXII Ijiraq ( S ′ = 19.5 ± 0.9 ). We… Expand
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
Probing the origin of the dark material on Iapetus
Among the icy satellites of Saturn, Iapetus shows a striking dichotomy between its leading and trailing hemispheres, the former being significantly darker than the latter. Thanks to the Visual andExpand
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
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 Irregular Satellites of Saturn Tilmann Denk
The outer or irregular moons of Saturn are a class of objects that is very distinct from the other satellites treated in this book. It not only has more objects (38 are presently known) than theExpand
THE COLORS OF EXTREME OUTER SOLAR SYSTEM OBJECTS
Extreme outer solar system objects have possible origins beyond the Kuiper Belt edge, high inclinations, very large semimajor axes, or large perihelion distances. Thirty-three such objects wereExpand
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
Evidence for a Recent Collision in Saturn’s Irregular Moon Population
Using CFHT imaging data, we searched a 1.1 deg2 field on each side of Saturn down to magnitude m w ≃ 26.3, corresponding to diameters of D ≃ 3 km. We detected 120 objects, which were comoving withExpand
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
New orbits of irregular satellites designed for the predictions of stellar occultations up to 2020, based on thousands of new observations
Gomes-Junior et al. (2015) published 3613 positions for the 8 largest irregular satellites of Jupiter and 1787 positions for the largest irregular satellite of Saturn, Phoebe. These observations wereExpand

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
The Dark Side of Iapetus: Additional Evidence for an Exogenous Origin
The saturnian satellite Iapetus presents one of the most unusual appearances of any object in the Solar System: one hemisphere is about 10 times as bright as the other. The origin of the darkExpand
Spectrophotometry of the small satellites of Saturn and their relationship to Iapetus, Phoebe, and Hyperion
Abstract We have obtained broadband spectrophotometric observations of four of the recently discovered small satellites of Saturn (Gladman et al., 2001, Nature 412, 163–166). The new data enable anExpand
The phase curve survey of the irregular saturnian satellites : A possible method of physical classification
Abstract During its 2005 January opposition, the saturnian system could be viewed at an unusually low phase angle. We surveyed a subset of Saturn's irregular satellites to obtain their trueExpand
Physical survey of 24 Centaurs with visible photometry
Abstract We present optical observations of 24 Centaurs performed between 1998 and 2002 with the University of Hawaii 2.2-m telescope. This is the largest such Centaur survey to date. We reportExpand
The dark side of Iapetus
Abstract This paper presents new photometric and spectrophotometric observations of the dark (leading) hemisphere of Saturn's satellite Iapetus. Spectrophotometry from 0.3–1.0 um (May 1979) shows theExpand
Pluto's Lightcurve: Results from Four Oppositions
Abstract The rotational lightcurve, phase function, and orbital lightcurve of the Pluto-Charon system were measured in blue light over four consecutive oppositions spanning 1980 to 1983. ComparedExpand
Eight-color photometry of Hyperion, Iapetus, and Phoebe
Abstract Eight-color spectrophotometry was obtained of Phoebe, Hyperion, and the dark side of Iapetus. Our observed V magnitudes and Voyager-derived diameters yield geometric albedos of 0.07 forExpand
Phoebe: Albedo Map and Photometric Properties
Using clear-filter images from Voyager 2 (effective wavelength 0.48 μm), we have constructed the first-ever digital albedo map of Saturn's moon Phoebe. Most normal reflectances in this new map areExpand
