Constraints on MOND theory from radio tracking data of the Cassini spacecraft

, 2014
The MOdified Newtonian Dynamics (MOND) is an attempt to modify the gravitation theory to solve the Dark Matter problem. This phenomenology is very successful at the galactic level.

Investigating Tidal Stripping of a Preexisting Moon as the Origin of Saturn’s Young Icy Rings

The Astrophysical Journal Letters
The origin of Saturn’s rings has been debated for decades. Measurements from Voyager and Cassini have suggested that the rings could be as young as ∼100 Myr and composed of nearly pure ice. Several scenarios have been proposed to explain these properties.

A Gas-poor Planetesimal Capture Model for the Formation of Giant Planet Satellite Systems

, 2005
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 ...

Topographic Relaxation of Complex Impact Craters in a Clathrate Crust on Titan

The Planetary Science Journal
Titan’s impact craters are significantly shallower than fresh craters on Ganymede, which are often used as templates for fresh craters on Titan. The presence of a clathrate crust on Titan, which would insulate the ice shell and maintain warmer ice near ...

Extensional tectonics of the Saturnian Satellites [PDF]

The saturnian satellites were imaged by the Voyager spacecraft at sufficient resolutions to reveal landforms that indicate histories of extensional tectonics for several of these bodies.

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 ...
