Irregular Satellites of the Planets: Products of Capture in the Early Solar System

All four giant planets in the Solar system possess irregular satellites, characterized by large, highly eccentric and/or inclined orbits that are distinct from the nearly circular, uninclined orbits of the regular satellites. This difference can be traced directly to different modes of formation. Whereas the regular satellites grew by accretion within circumplanetary disks the irregular satellites were captured from initially heliocentric orbits at an early epoch. Recently, powerful survey… 

Orbital Stability of Exomoons and Submoons with Applications to Kepler 1625b-I

An intriguing question in the context of dynamics arises: could a moon possess a moon itself? Such a configuration does not exist in the solar system, although this may be possible in theory.

Cladistical Analysis of the Jovian and Saturnian Satellite Systems

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.


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

Effects of the planetary migration on some primordial satellites of the outer planets - I. Uranus’ case

Context. During the first hundred million years after the formation of our solar system, the four giant planets are believed to have migrated significantly (by up ≈20 AU). The current scenario and

Six Hot Topics in Planetary Astronomy

Six hot topics in modern planetary astronomy are described: (1) light-curves and densities of small bodies, (2) colors of Kuiper belt objects and the distribution of the ultrared matter, (3)

The Transits of Extrasolar Planets with Moons

The search for extrasolar planets is strongly motivated by the goal of characterizing how frequent habitable worlds and life may be within the Galaxy. Whilst much effort has been spent on searching

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 slightly

Solar System Physics for Exoplanet Research

Over the past three decades, we have witnessed one of the great revolutions in our understanding of the cosmos—the dawn of the Exoplanet Era. Where once we knew of just one planetary system (the



Chaotic capture of Jupiter's Trojan asteroids in the early Solar System

It is shown that the Trojans could have formed in more distant regions and been subsequently captured into co-orbital motion with Jupiter during the time when the giant planets migrated by removing neighbouring planetesimals.

Gas Drag and the Orbital Evolution of a Captured Triton

Abstract Gas drag is a possible mechanism for capturing Triton. We examine the energetics of gas drag capture, compare the role of gas drag in subsequent orbital evolution with that of tides, and

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 and

Constraints on the Orbital Evolution of Triton

We present simulations of Triton's postcapture orbit that confirm the importance of Kozai-type oscillations in its orbital elements. In the context of the tidal orbital evolution model, these
