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 objects have near-infrared colors consistent with C-, P-, and D-type asteroids, although J XII Ananke and S IX Phoebe show weak indications of possible water features in the H filter. The four members of the Himalia family have similar near-infrared colors, as do the two members of the Gallic family, S XX… Expand

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
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
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
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

TLDR
The case for implementation of moving target tracking is presented, a feature that will benefit from the heritage of JWST and enable a broader range of solar system observations. Expand
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
DISCOVERY OF 11 NEW T DWARFS IN THE TWO MICRON ALL SKY SURVEY, INCLUDING A POSSIBLE L/T TRANSITION BINARY
We present the discovery of 11 new T dwarfs, found during the course of a photometric survey for mid-to-late T dwarfs in the 2MASS Point Source Catalog and from a proper-motion-selected sample ofExpand
THE 3 μm SPECTRUM OF JUPITER's IRREGULAR SATELLITE HIMALIA
We present a medium resolution spectrum of Jupiter's irregular satellite Himalia covering the critical 3 μm spectral region. The spectrum shows no evidence for aqueously altered phyllosilicates, asExpand
Orbital Modification of the Himalia Family during an Early Solar System Dynamical Instability
Among the irregular satellites orbiting Jupiter, the Himalia family is characterized by a high velocity dispersion dv of several hundred m s-1 among its members, inconsistent with a collisionalExpand
