Masses for free-floating planets and dwarf planets [PDF]
Research in Astronomy and Astrophysics, 2020 The mass and distance functions of free-floating planets (FFPs) would give major insights into the formation and evolution of planetary systems, including any systematic differences between those in the disk and bulge.

Probing Planets with Exomoons: The Cases of Kepler-1708 b and Kepler-1625 b [PDF]
Astrophysical Journal Letters, 2022 The tidal interactions between a planet and moon can provide insight into the properties of the host planet. The recent exomoon candidates Kepler-1708 b-i and Kepler-1625 b-i are Neptune-sized satellites orbiting Jupiter-like planets and provide an ...

Upper atmospheres and ionospheres of planets and satellites [PDF]
, 2017 The upper atmospheres of the planets and their satellites are more directly exposed to sunlight and solar wind particles than the surface or the deeper atmospheric layers.

Web of resonances and possible path of evolution of the small Uranian satellites [PDF]
Astrophysics and Space Science, 2022 Satellite systems around giant planets are immersed in a region of complex resonant configurations. Understanding the role of satellite resonances contributes to comprehending the dynamical processes in planetary formation and posterior evolution.

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 ...

Binary planet formation through tides [PDF]
Monthly notices of the Royal Astronomical Society, 2023 The search for satellites around exoplanets represents one of the greatest challenges in advancing the characterization of planetary systems. Currently, we can only detect massive satellites, which resemble additional planetary companions rather than ...

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.

Investigating the formation of small Solar System objects using stellar occultations by satellites: present, future and its use to update satellite orbits [PDF]
Philosophical TransactionsThe history of the outer solar system is intrinsically related to the Giant Planets migration. A massive disk of material within a radius of 30 au was scattered during the planetary migration, creating different dynamic populations in the Transneptunian ...

Outer irregular satellites of the planets and their relationship with asteroids, comets and Kuiper Belt objects [PDF]
Proceedings of the International Astronomical Union, 2005 Outer satellites of the planets have distant, eccentric orbits that can be highly inclined or even retrograde relative to the equatorial planes of their planets.
