A Schumann-like resonance on Titan driven by Saturn's magnetosphere possibly revealed by the Huygens Probe

Berthelier, J. J.; Krasnoselskikh, V.; López-Moreno, J. J. +9 more

The low-frequency data collected with the antenna of the Permittivity, Wave and Altimetry experiment on board the Huygens Probe that landed on Titan on 14 January 2005 have been thoroughly analyzed considering different possible natural and artificial effects. Although a definite conclusion is still subject to the outcome of complementary inquirie…

Discharge experiments simulating chemical evolution on the surface of Titan

Fischer, Georg; Rucker, Helmut O.; Lammer, Helmut +7 more

Saturn's moon Titan has been considered as one of the few places in our Solar System, where atmospheric and surface conditions could have produced organic compounds essential as precursors for an evolution of life. The Cassini-Huygens mission has provided new data on Titan's atmosphere and surface, which enabled us to simulate the chemical process…

Speed of sound measurements and the methane abundance in Titan's atmosphere

Lorenz, R. D.; Hagermann, A.; Leese, M. R. +6 more

Aboard the Huygens probe, which descended through Titan's atmosphere in January 2005, was the Surface Science Package (SSP), a set of 9 sensors, including a speed-of-sound sensor. We present the first detailed description of the SSP speed of sound measurements and report constraints on the methane content in Titan's lower atmosphere based on these…

The 2003 November 14 occultation by Titan of TYC 1343-1865-1. II. Analysis of light curves

Dhillon, V. S.; Irwin, P. G. J.; Taylor, F. W. +6 more

We observed a stellar occultation by Titan on 2003 November 14 from La Palma Observatory using ULTRACAM with three Sloan filters: u, g, and i (358, 487, and 758 nm, respectively). The occultation probed latitudes 2° S and 1° N during immersion and emersion, respectively. A prominent central flash was present in only the i filter, indicating wavele…
