Formation of Giant Planet Satellites [PDF]
The Astrophysical Journal, 2020 Abstract Recent analyses have shown that the concluding stages of giant planet formation are accompanied by the development of a large-scale meridional flow of gas inside the planetary Hill sphere. This circulation feeds a circumplanetary disk that viscously expels gaseous material back into the parent nebula, maintaining the system in a

Using satellites to probe extrasolar planet formation [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractPlanetary satellites are an integral part of the hierarchy of planetary systems. Here we make two predictions concerning their formation. First, primordial satellites, which have an array of distinguishing characteristics, form only around giant planets.

Constraints from Comets on the Formation and Volatile Acquisition of the Planets and Satellites [PDF]
Space Science Reviews, 2015 Comets play a dual role in understanding the formation and evolution of the solar system. First, the composition of comets provides information about the origin of the giant planets and their moons because comets formed early and their composition is not expected to have evolved significantly since formation.

Formation of the regular satellites of giant planets in an extended gaseous nebula I: subnebula model and accretion of satellites [PDF]
Icarus, 2003 We model the subnebulae of Jupiter and Saturn wherein satellite accretion took place. We expect a giant planet subnebula to be composed of an optically thick (given gaseous opacity) inner region inside of the planet's centrifugal radius (located at r(sub c, sup J) = l5R(sub J) for Jupiter and r(sub c, sup S) = 22R(sub S) for Saturn), and an optically ...

A gas-poor planetesimal capture model for the formation of giant planet satellite systems [PDF]
Icarus, 2006 Assuming that an unknown mechanism (e.g., gas turbulence) removes most of the subnebula gas disk in a timescale shorter than that for satellite formation, we develop a model for the formation of regular (and possibly at least some of the irregular) satellites around giant planets in a gas-poor environment.

N-BODY SIMULATIONS OF SATELLITE FORMATION AROUND GIANT PLANETS: ORIGIN OF ORBITAL CONFIGURATION OF THE GALILEAN MOONS [PDF]
The Astrophysical Journal, 2012 As the number of discovered extrasolar planets has been increasing, diversity of planetary systems requires studies of new formation scenarios. It is important to study satellite formation in circumplanetary disks, which is often viewed as analogous to formation of rocky planets in protoplanetary disks.

Monthly Notices of the Royal Astronomical SocietyABSTRACT Several stars show deep transits consistent with discs of roughly $1\mathrm{\, R}_\odot$ seen at moderate inclinations, likely surrounding planets on eccentric orbits. We show that this configuration arises naturally as a result of planet–planet scattering when the planets possess satellite systems.

Origin and Formation of the Regular Satellites around Planets
, 2018 The presence of regular satellites around planets, thought to have formed in situ, is the rule rather than the exception in our Solar System. These objects presumably formed in the last stages of accretion of their parent planets and our understanding of their origin is therefore tied to that of the formation of planets. In spite of the recent progress
