N-body Simulations of Satellite Formation around Giant Planets: Origin of Orbital Configuration of the Galilean Moons

, 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 ...

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

The 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 ...

The Optical Aurorae of Europa, Ganymede, and Callisto

The Planetary Science Journal, 2023
The tenuous atmospheres of the Galilean satellites are sourced from their surfaces and produced by a combination of plasma-surface interactions and thermal processes. Even though they are thin, these atmospheres can be studied via their auroral emissions,

Mass-wasting Features on Galilean Icy Moons: Morphological Analysis and Implications

The Planetary Science Journal
This study investigates mass-wasting features on the icy Galilean satellites Europa, Ganymede, and Callisto. Through comparative morphological analysis, we identified and classified slides, slumps, and flow-like deposits as mass-wasting categories using ...

Io’s Optical Aurorae in Jupiter’s Shadow

The Planetary Science Journal, 2023
Decline and recovery timescales surrounding eclipse are indicative of the controlling physical processes in Io’s atmosphere. Recent studies have established that the majority of Io’s molecular atmosphere, SO _2 and SO, condenses during its passage ...

A Primordial Origin of the Laplace Relation Among the Galilean Satellites

, 2002
Understanding the origin of the orbital resonances of the Galilean satellites of Jupiter will constrain the longevity of the extensive volcanism on Io, may explain a liquid ocean on Europa, and may guide studies of the dissipative properties of stars and

Length, Width, and Relative Age Analysis of Lineaments in the Galileo Regional Maps with LineaMapper

The Planetary Science Journal
The Galileo regional mosaics (“RegMaps”) show Europa’s extensive regional-scale tectonic features under similar illumination conditions. Detailed lineament studies can help constrain resurfacing events and formation mechanisms, but most lineament maps ...

A semi-analytical model for exploring Galilean satellites formation from a massive disk

, 2015
A better knowledge of Jovian satellites' origins will bring light on the environment that surrounded Jupiter during its formation and can help us to understand the characteristics of this unique satellite system.

Modeling the Jovian subnebula: I - Thermodynamical conditions and migration of proto-satellites [PDF]

, 2005
We have developed an evolutionary turbulent model of the Jovian subnebula consistent with the extended core accretion formation models of Jupiter described by Alibert et al. (2005b) and derived from Alibert et al. (2004,2005a).

Surface Deposition of Icy Dust Entrained in Europa’s Plumes

The Planetary Science Journal
Europa, an icy moon of Jupiter, features complex surface characteristics shaped by tidal forces and interactions with its subsurface ocean, making it a key target for astrobiology research.
