Near-infrared (0.8-4.0 µm) spectroscopy of Mimas, Enceladus, Tethys, and Rhea
Brown, R. H.; Emery, J. P.; Burr, D. M. +2 more
Spectral measurements from the ground in the time leading up to the Cassini mission at Saturn provide important context for the interpretation of the forthcoming spacecraft data. Whereas ground-based observations cannot begin to approach the spatial scales Cassini will achieve, they do possess the benefits of better spectral resolution, a broader …
Imaging Saturn's rings with CAMIRAS: thermal inertia of B and C rings
Pantin, E.; Lagage, P. O.; Ferrari, C. +2 more
Thermal inertias Γ of Saturn's B and C ring particles have been derived from infrared observations using the CAMIRAS camera mounted on the Canada-France-Hawaii Telescope. They are respectively Γ_B=5+18-2 {J m-2 K-1 s-1/2} and Γ_C=6+12-4 {J m-2 K-1 s<…
Re-determination of Phoebe's orbit
Qiao, R. C.; Shen, K. X.; Dourneau, G. +2 more
In order to improve the orbit of Phoebe, the ninth satellite of the Saturnian system, 101 new observations were made by our research team in 2003, using a CCD detector of large size (2048×2048 pixels) mounted on the 1.56 m astrometric reflector at the Sheshan Station of Shanghai Astronomical Observatory. We fitted a numerical integration of its or…
