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 objects with in situ observations (Himalia and Phoebe) and provide diameters and albedo for 12 previously unmeasured objects, 10 Jovian and 2 Saturnian irregular satellites. The best-fit thermal model beaming parameters are comparable to what is observed for other small bodies in the outer solar system…

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 K2…
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 our…

Astrometric observations of outer Jovian satellites with the `Saturn' telescope. First results
The one-meter telescope-reflector `Saturn' (D=1 m, F = 4 m) was partially renovated at the Pulkovo observatory at the end of 2014. The telescope was equipped by CCD camera S2C with 14x14 arcmin field…
NEOWISE Reactivation Mission Year Two: Asteroid Diameters and Albedos
The Near-Earth Object Wide-Field Infrared Survey Explorer (NEOWISE) mission continues to detect, track, and characterize minor planets. We present diameters and albedos calculated from observations…
Cladistical Analysis of the Jovian and Saturnian Satellite Systems
TLDR
This work performs the first cladistical study of objects in a planetary science context, using the orbital, physical and compositional characteristics of satellites to classify the objects in the Jovian and Saturnian systems.

Space-Based Thermal Infrared Studies of Asteroids
Large-area surveys operating at mid-infrared wavelengths have proven to be a valuable means of discovering and characterizing minor planets. Through the use of radiometric models, it is possible to…
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 collisional…
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 the…

Cassini Imaging of Jupiter's Atmosphere, Satellites, and Rings
TLDR
Findings on Jupiter's zonal winds, convective storms, low-latitude upper troposphere, polar stratosphere, and northern aurora are reported, including previously unseen emissions arising from Io and Europa in eclipse, and a giant volcanic plume over Io's north pole are described.
Photometric properties of outer planetary satellites
Near-Infrared Spectroscopy of Centaurs and Irregular Satellites
We have obtained near-infrared spectra of the four brightest known Centaurs and of five irregular satellites of giant planets. Many of these objects show 1.5 and 2.0 μm absorption bands indicative of…
Capture of Irregular Satellites at Jupiter
The irregular satellites of outer planets are thought to have been captured from heliocentric orbits. The exact nature of the capture process, however, remains uncertain. We examine the possibility…
