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.

The formation of transiting circumplanetary debris discs from the disruption of satellite systems during planet–planet scattering [PDF]

Monthly Notices of the Royal Astronomical Society
ABSTRACT 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.

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.

Formation of the Satellite Systems of the Major Planets

Publications of the Astronomical Society of Australia, 1977
It is well known that the satellite systems of the major planets Jupiter, Saturn and Uranus share many of the same regular features that can be seen in the planetary system of the Sun. The inner satellite orbits are nearly circular and lie in the plane defined by the axis of rotation of the central body. Again the distances Rn of the regular satellites,

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

Detecting Exomoons from Radial Velocity Measurements of Self-luminous Planets: Application to Observations of HR 7672 B and Future Prospects [PDF]

Astronomical Journal, 2023
The detection of satellites around extrasolar planets, so called exomoons, remains a largely unexplored territory. In this work, we study the potential of detecting these elusive objects from radial velocity monitoring of self-luminous, directly imaged ...

Presence of liquid water during the evolution of exomoons orbiting ejected free-floating planets [PDF]

International Journal of Astrobiology, 2023
Free-floating planets (FFPs) can result from dynamical scattering processes happening in the first few million years of a planetary system's life. Several models predict the possibility, for these isolated planetary-mass objects, to retain exomoons ...

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.

Detectability of satellites around directly imaged exoplanets and brown dwarfs [PDF]

Monthly notices of the Royal Astronomical Society, 2022
Satellites around substellar companions are a heterogeneous class of objects with a variety of different formation histories. Focusing on potentially detectable satellites around exoplanets and brown dwarfs, we might expect to find objects belonging to

Formation of moon systems around giant planets [PDF]

Astronomy & Astrophysics, 2019
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 last stages of formation of their parent planet ...
