The Formation of Nitriles in Hydrocarbon-Rich Atmospheres of Planets and Their Satellites:  Laboratory Investigations by the Crossed Molecular Beam Technique

Accounts of Chemical Research, 2001
Crossed molecular beam experiments of cyano radicals, CN(X(2)Sigma(+)), reacting with unsaturated hydrocarbons have been performed to investigate synthetic routes to nitriles formation in hydrocarbon-rich atmospheres of planets and their moons. We have verified that all cyano radical reactions with acetylene, ethylene, methylacetylene, allene, benzene,

Formation of the regular satellite systems and rings of the major planets

The Moon and the Planets, 1979
In this paper, we apply the ideas presented by one of us (Prentice, 1978a, b) for the development of the proto-solar cloud into a system of Laplacian rings to the development of the protoplanetary clouds which ultimately led to Jupiter, Saturn and Uranus.

Irregular Satellites in the Context of Planet Formation

Space Science Reviews, 2005
All four giant planets in the solar system possess irregular satellites, characterized by large, highly eccentric and/or highly inclined orbits. These bodies were likely captured from heliocentric orbit, probably in association with planet formation itself. Enabled by the use of large-format digital imagers on ground-based telescopes, new observational
