The roles of charge exchange and dissociation in spreading Saturn's neutral clouds

, 2012
Neutrals sourced directly from Enceladus's plumes are initially confined to a dense neutral torus in Enceladus's orbit around Saturn. This neutral torus is redistributed by charge exchange, impact/photodissociation, and neutral-neutral collisions to ...

Curtain-based Maps of Eruptive Activity in Enceladus’s South-polar Terrain at 15 Cassini Epochs

The Planetary Science Journal
We map surface eruptive activity in Cassini images of Enceladus’s south-polar terrain (SPT) at 15 epochs spanning late 2009 to late 2015 using a refined curtain approach derived from that of J. N. Spitale et al. (S2015).

Dynamics of Enceladus and Dione inside the 2:1 Mean-Motion Resonance under Tidal Dissipation

, 2008
In a previous work (Callegari and Yokoyama 2007, Celest. Mech. Dyn. Astr. vol. 98), the main features of the motion of the pair Enceladus-Dione were analyzed in the frozen regime, i.e., without considering the tidal evolution.

Exploring the Interior Structure and Mode of Tidal Heating in Enceladus

The Planetary Science Journal
Enceladus is among the most intriguing bodies in the solar system due to its astrobiological potential. Determining the extent and duration of habitability (i.e., sustained habitability ) requires characterizing the interior properties and the level and ...

Impacts on Ocean Worlds Are Sufficiently Frequent and Energetic to Be of Astrobiological Importance

The Planetary Science Journal
Evidence for the beneficial role of impacts in the creation of urable or habitable environments on Earth prompts the question of whether meteorite impacts could play a similar role at other potentially urable/habitable worlds like Enceladus, Europa, and ...

Dust Ablation on the Giant Planets: Consequences for Stratospheric Photochemistry

, 2017
Ablation of interplanetary dust supplies oxygen to the upper atmospheres of Jupiter, Saturn, Uranus, and Neptune. Using recent dynamical model predictions for the dust influx rates to the giant planets (Poppe, A.R.~et al.~[2016], Icarus 264, 369), we ...

A Potential Mushy Source for the Geysers of Enceladus and Other Icy Satellites

Geophysical Research Letters
Enceladus is a target for astrobiology due to the H2O plume ejecta measured by the Cassini spacecraft and the inferred subsurface ocean that could be the source of the geysers.

Enough Sulfur and Iron for Potential Life Make Enceladus’s Ocean Fully Habitable

The Astrophysical Journal Letters
The Cassini spacecraft revealed life-forming elements like CHNOP and diverse organic compounds from Enceladus’s ocean. However, the availability of minor but bio-essential nutrients such as iron and sulfur remains unknown.
