TL;DR: In this paper, the authors report the orbital distribution of the trans-Neptunian objects (TNOs) discovered during the Canada-France Ecliptic Plane Survey (CFEPS), whose discovery phase ran from early 2003 until early 2007.
Journal ArticleDOI
The identification of liquid ethane in Titan’s Ontario Lacus
Robert H. Brown,L. A. Soderblom,Jason M. Soderblom,Roger N. Clark,Ralf Jaumann,Jason W. Barnes,Christophe Sotin,B. J. Buratti,Kevin H. Baines,P. D. Nicholson +9 more
TL;DR: Infrared spectroscopic data obtained by the Visual and Infrared Mapping Spectrometer (VIMS) on board the Cassini spacecraft strongly indicate that ethane, probably in liquid solution with methane, nitrogen and other low-molecular-mass hydrocarbons, is contained within Titan’s Ontario Lacus.
Journal ArticleDOI
Composition and physical properties of Enceladus' surface
Robert H. Brown,R. N. Clark,Bonnie J. Buratti,Dale P. Cruikshank,Jason W. Barnes,Rachel Mastrapa,James M. Bauer,S. Newman,Tom Momary,Kevin H. Baines,Giancarlo Bellucci,Fabrizio Capaccioni,Priscilla Cerroni,M. Combes,Angioletta Coradini,Pierre Drossart,Vittorio Formisano,Ralf Jaumann,Yves Langevin,Dennis L. Matson,Thomas B. McCord,Robert M. Nelson,P. D. Nicholson,Bruno Sicardy,Christophe Sotin +24 more
TL;DR: Observations of Saturn's satellite Enceladus using Cassini's Visual and Infrared Mapping Spectrometer instrument were obtained during three flybys in 2005, and upper limits of 140 kelvin are derived for the temperatures in the tiger stripes.
Journal ArticleDOI
Release of volatiles from a possible cryovolcano from near-infrared imaging of Titan
Christophe Sotin,Ralf Jaumann,Bonnie J. Buratti,Robert H. Brown,Roger N. Clark,L. A. Soderblom,Kevin H. Baines,Giancarlo Bellucci,Jean-Pierre Bibring,Fabrizio Capaccioni,Priscilla Cerroni,M. Combes,Angioletta Coradini,Dale P. Cruikshank,Pierre Drossart,Vittorio Formisano,Yves Langevin,Dennis L. Matson,Thomas B. McCord,Robert M. Nelson,P. D. Nicholson,Bruno Sicardy,S. Lemouelic,Sebastien Rodriguez,Katrin Stephan,C.K. Scholz +25 more
TL;DR: Near-infrared images of Titan obtained on 26 October 2004 by the Cassini spacecraft show that a widespread methane ocean does not exist; subtle albedo variations instead suggest topographical variations, as would be expected for a more solid (perhaps icy) surface.
Journal ArticleDOI
Evidence for a Polar Ethane Cloud on Titan
Caitlin A. Griffith,Paulo Penteado,Pascal Rannou,Robert H. Brown,Vincent Boudon,Kevin H. Baines,Roger N. Clark,Pierre Drossart,B. J. Buratti,P. D. Nicholson,Christopher P. McKay,Athena Coustenis,A. Negrao,Ralf Jaumann +13 more
TL;DR: Spectra from Cassini's Visual and Infrared Mapping Spectrometer reveal the presence of a vast tropospheric cloud on Titan and derived characteristics indicate that this cloud is composed of ethane and forms as a result of stratospheric subsidence and the particularly cool conditions near the moon's north pole.
