Origin of the Moon's orbital inclination from resonant disk interactions
Article Abstract:
It is likely that the Moon's substantial orbital inclination is a natural outcome of its formation from an impact-generated disk. It is suggested that the Moon would have co-existed for some time with an inner disk containing a good fraction of a lunar mass. The inclination-generating mechanism proposed by this research involves a resonance between this inner remnant disk and the Moon. The inclination of the Moon's orbit may be a significant indicator of the early state of the post-impact system.

A common mass scaling for satellite systems of gaseous planets
Article Abstract:
The study of a model in which satellites grow within an actively supplied circumplanetary disk which is maintained by a time dependent inflow of gas and solids from heliocentric orbit during the end stages of the formation of the planet is presented. Most properties of the satellite systems of Jupiter, Saturn and Uranus originate naturally suggesting that similar processes could limit the largest moons of extrasolar Jupiter-mass planets to Moon-to-Mars size.

Lunar accretion from an impact-generated disk
Article Abstract:
The favoured theory for the Moon's origin is the 'giant impact' model because it may account for certain geochemical and dynamical characteristics. While the impact process has often been modelled, the process of moon accretion has largely been ignored. An investigation of how a moon can be formed from a circumterrestrial disk is presented. It is suggested that a single large moon could be formed from debris in about a year. The study points to a direct interaction between the angular momentum of the initial disk and the resulting moon's mass.
