A common mass scaling for satellite systems of gaseous planets

  author={Robin M. Canup and William Rankin. Ward},
The Solar System's outer planets that contain hydrogen gas all host systems of multiple moons, which notably each contain a similar fraction of their respective planet's mass (∼10-4). This mass fraction is two to three orders of magnitude smaller than that of the largest satellites of the solid planets (such as the Earth's Moon), and its common value for gas planets has been puzzling. Here we model satellite growth and loss as a forming giant planet accumulates gas and rock-ice solids from… 
Formation of moon systems around giant planets
The four major satellites of Jupiter, known as the Galilean moons, and Saturn’s most massive satellite, Titan, are believed to have formed in a predominantly gaseous circum-planetary disk during the
Formation of Regular Satellites from Ancient Massive Rings in the Solar System
It is shown that most regular satellites in the solar system probably formed in this way, and predicts that Uranus and Neptune once had massive, Saturn-like rings, which gave birth to moons and then disappeared.
Large planets may not form fractionally large moons
One of the unique aspects of Earth is that it has a fractionally large Moon, which is thought to have formed from a Moon-forming disk generated by a giant impact. The Moon stabilizes the Earth’s spin
Habitability of Earth-mass Planets and Moons in the Kepler-16 System
We demonstrate that habitable Earth-mass planets and moons can exist in the Kepler-16 system, known to host a Saturn-mass planet around a stellar binary, by investigating their orbital stability in
The field of exoplanetary science has experienced a recent surge of new systems that is largely due to the precision photometry provided by the Kepler mission. The latest discoveries have included
Growth and evolution of satellites in a Jovian massive disc
The formation of satellite systems in circum-planetary discs is considered to be similar to the formation of rocky planets in a proto-planetary disc, especially Super-Earths. Thus, it is possible to
Resonant Removal of Exomoons During Planetary Migration
Jupiter and Saturn play host to an impressive array of satellites, making it reasonable to suspect that similar systems of moons might exist around giant extrasolar planets. Furthermore, a
Formation of single-moon systems around gas giants
Context. Several mechanisms have been proposed to explain the formation process of satellite systems, and relatively large moons are thought to be born in circumplanetary disks. Making a single-moon
Exomoons: from icy to temperate worlds
Giant planets may host significant populations of moons. In our own solar system, Jupiter and Saturn together harbor over 120 natural satellites, six of which have diameters between 1500 and more
Compared to the giant planets in the solar system, exoplanets have many remarkable properties, such as the prevalence of giant planets on eccentric orbits and the presence of hot Jupiters.


Stability of Satellites around Close-in Extrasolar Giant Planets
We investigate the long-term dynamical stability of hypothetical moons orbiting extrasolar giant planets. Stellar tides brake a planet's rotation and, together with tidal migration, act to remove
The Stability of Multi-Planet Systems
A system of two small planets orbiting the Sun on low-eccentricity, low-inclination orbits is stable with respect to close encounters if the initial semi-major axis difference, Δ, measured in mutual
Disk Accretion onto High-Mass Planets
We analyze the nonlinear, two-dimensional response of a gaseous, viscous protoplanetary disk to the presence of a planet of one Jupiter mass (1 MJ) and greater that orbits a 1 M☉ star by using the
Formation of the Galilean Satellites: Conditions of Accretion
We examine formation conditions for the Galilean satellites in the context of models of late-stage giant planet accretion and satellite-disk interactions. We first reevaluate the current standard, in
Habitable moons around extrasolar giant planets
It is argued that rocky moons orbiting these companions could be habitable if the planet–moon system orbits the parent star within the so-called 'habitable zone'10, where life-supporting liquid water could be present.
Saturn's moon Phoebe as a captured body from the outer Solar System
Phoebe's composition is close to that derived for other solar nebula bodies such as Triton and Pluto, but is very different from that of the regular satellites of Saturn, supporting Phoe be's origin as a captured body from the outer Solar System.
Three-dimensional calculations of high- and low-mass planets embedded in protoplanetary discs
We analyse the non-linear, three-dimensional response of a gaseous, viscous protoplanetary disc to the presence of a planet of mass ranging from 1 Earth mass (1 M⊕) to 1 Jupiter mass (1 MJ) by using
Planetary torques as the viscosity of protoplanetary disks
We revisit the idea that density wave wakes of planets drive accretion in protostellar disks. The effects of many small planets can be represented as a viscosity if the wakes damp locally but the
Urey Prize Lecture: On the Diversity of Plausible Planetary Systems
Abstract Models of planet formation and of the orbital stability of planetary systems are used to predict the variety of planetary and satellite systems that may be present within our galaxy. A new
