Giant impacts in the Saturnian System: a possible origin of diversity in the inner mid-sized satellites

, 2011
It is widely accepted that Titan and the mid-sized regular satellites around Saturn were formed in the circum-Saturn disk. Thus, if these mid-sized satellites were simply accreted by collisions of similar ice-rock satellitesimals in the disk, the ...

NEOWISE: Observations of the Irregular Satellites of Jupiter and Saturn [PDF]

, 2015
We present thermal model fits for 11 Jovian and 3 Saturnian irregular satellites based on measurements from the WISE/NEOWISE dataset. Our fits confirm spacecraft-measured diameters for the objects with in situ observations (Himalia and Phoebe) and ...

Spitzer IRS Observations of Titan as a Precursor to JWST MIRI Observations

The Planetary Science Journal, 2023
In this work, we present for the first time infrared spectra of Titan from the Spitzer Space Telescope (2004–2009). The data are from both the short wavelength–low resolution (SL; 5.13–14.29 μ m, R ∼ 60–127) and short wavelength–high resolution (SH; 9.89–

Shallow normal fault slopes on Saturnian icy satellites [PDF]

Journal of Geophysical Research: Planets, 2015
AbstractFault dips are a function of the coefficient of internal friction, μi, of the lithospheric material. Laboratory deformation experiments of H2O ice at conditions applicable to icy bodies yield 0 ≤ μi ≤ 0.55 such that normal faults dip between 45° and 59°.

IR SPECTRAL MAPPING OF THE MARTIAN SOUTH POLAR RESIDUAL CAP USING CRISM [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Polycyclic aromatic hydrocarbons (PAHs) are considered to be important in theories of abiogenesis (Allamandola, 2011) . There is evidence that PAHs have been detected on two icy Saturnian satellites using the Visual and Infrared Mapping Spectrometer ...

Last giant impact on the Neptunian system. Constraints on oligarchic masses in the trans-Saturnian region [PDF]

, 2011
Stochastic impacts by large bodies are, at present, the usually accepted mechanisms able to account for the obliquity of the ice giants. We attempt to set constraints on giant impacts as the cause of Neptune's current obliquity in the framework of modern

Saturn's icy satellites and rings investigated by Cassini - VIMS. III. Radial compositional variability

, 2012
In the last few years Cassini-VIMS, the Visible and Infared Mapping Spectrometer, returned to us a comprehensive view of the Saturn's icy satellites and rings. After having analyzed the satellites' spectral properties (Filacchione et al.

A Search for Water Masers in the Saturnian System

, 2010
We searched for H2O 6(1,6)-5(2,3) maser emission at 22.235 GHz from several Saturnian satellites with the Nobeyama 45m radio telescope in May 2009. Observations were made for Titan, Hyperion, Enceladus and Atlas, for which Pogrebenko et al.

New Saturnian satellites

Eos, Transactions American Geophysical Union, 1982
Four, and possibly as many as six, new satellites of Saturn have been found as a result of data from the Voyager 2 encounter with the planet in August 1981. The discoveries bring the number of Saturnian satellites to between 21 and 23. The two ‘possible’ satellites were seen in only one observation each, so their orbits are not yet confirmed.The ...
