Cassini Observes the Active South Pole of Enceladus
- C. Porco, P. Helfenstein, +22 authors S. Squyres
- Geology, Medicine
- Science
- 10 March 2006
Cassini has identified a geologically active province at the south pole of Saturn's moon Enceladus. In images acquired by the Imaging Science Subsystem (ISS), this region is circumscribed by a chain… Expand
Recent Origin of the Solar System Dust Bands
- D. Nesvorný, W. Bottke, H. Levison, L. Dones
- Physics
- 1 July 2003
Infrared Astronomical Satellite (IRAS) observations in 1983 revealed the existence of several solar system dust bands. These dust bands are believed to be debris produced by recent disruption events… Expand
Cassini Imaging of Jupiter's Atmosphere, Satellites, and Rings
- C. Porco, R. West, +21 authors A. Vasavada
- Geology, Medicine
- Science
- 7 March 2003
The Cassini Imaging Science Subsystem acquired about 26,000 images of the Jupiter system as the spacecraft encountered the giant planet en route to Saturn. We report findings on Jupiter's zonal… Expand
How Long-Lived Are the Hypothetical Trojan Populations of Saturn, Uranus, and Neptune?
- D. Nesvorný, L. Dones
- Physics
- 1 December 2002
We investigate the possibility that fractions of the primordial populations at the triangular Lagrangian points of Saturn, Uranus, and Neptune have survived to the present and form (as yet… Expand
Dynamical evolution of ecliptic comets
- M. Duncan, H. Levison, L. Dones
- Physics
- 2004
Ecliptic comets are those with T > 2, where T is the Tisserand parameter with respect to Jupiter. In this chapter, we review the enormous progress that has been made in our understanding of the… Expand

Cassini Imaging Science: Initial Results on Saturn's Rings and Small Satellites
Images acquired of Saturn's rings and small moons by the Cassini Imaging Science Subsystem (ISS) during the first 9 months of Cassini operations at Saturn have produced many new findings. These… Expand
Cratering rates on the Galilean satellites.
- K. Zahnle, L. Dones, H. Levison
- Geology, Medicine
- Icarus
- 1 December 1998
We exploit recent theoretical advances toward the origin and orbital evolution of comets and asteroids to obtain revised estimates for cratering rates in the jovian system. We find that most,… Expand
Cassini Imaging Science: Initial Results on Phoebe and Iapetus
The Cassini Imaging Science Subsystem acquired high-resolution imaging data on the outer Saturnian moon, Phoebe, during Cassini's close flyby on 11 June 2004 and on Iapetus during a flyby on 31… Expand
Can planetesimals left over from terrestrial planet formation produce the lunar Late Heavy Bombardment
- W. Bottke, H. Levison, D. Nesvorný, L. Dones
- Physics
- 1 September 2007
Abstract The lunar Late Heavy Bombardment (LHB) defines a time between ∼3.8 to possibly 4.1 Gy ago when the Nectarian and early-Imbrium basins on the Moon with reasonably well-constrained ages were… Expand
On the origin of the unusual orbit of Comet 2P/Encke
- H. Levison, D. Terrell, P. Wiegert, L. Dones, M. Duncan
- Physics
- 1 May 2006
Abstract The orbit of Comet 2P/Encke is difficult to understand because it is decoupled from Jupiter—its aphelion distance is only 4.1 AU . We present a series of orbital integrations designed to… Expand
