Journal ArticleDOI
Analytic theory of Titan’s Schumann resonance: Constraints on ionospheric conductivity and buried water ocean
C. Béghin,Orélien Randriamboarison,Michel Hamelin,Erich Karkoschka,Christophe Sotin,Robert C. Whitten,Jean-Jacques Berthelier,R. Grard,Fernando Simões +8 more
TL;DR: In this article, an approximate model for the atypical Schumann resonance in Titan's atmosphere that accounts for the observations of electromagnetic waves and the measurements of atmospheric conductivity performed with the HASI-PWA (Huygens Atmospheric Structure and Permittivity, Wave and Altimetry) instrumentation was presented.
Journal ArticleDOI
Titan's native ocean revealed beneath some 45 km of ice by a Schumann-like resonance
TL;DR: In this article, a Schumann-like resonance trapped within Titan's atmospheric cavity was observed, triggered and sustained by strong electric currents induced in the ionosphere by Saturn's magnetospheric plasma flow.
Journal ArticleDOI
A Schumann-like resonance on Titan driven by Saturn's magnetosphere possibly revealed by the Huygens Probe
C. Béghin,Fernando Simões,Vladimir Krasnoselskikh,Konrad Schwingenschuh,Jean-Jacques Berthelier,Bruno P. Besser,Carlo Bettanini,R. Grard,Michel Hamelin,J. J. López-Moreno,Gregorio J. Molina-Cuberos,Tetsuya Tokano +11 more
TL;DR: In this paper, the authors analyzed the low-frequency data collected with the antenna of the Huygens Probe that landed on Titan on 14 January 2005 and concluded that the observations can be explained in terms of natural phenomena rather than being artifacts.
Journal ArticleDOI
New insights on Titan's plasma-driven Schumann resonance inferred from Huygens and Cassini data
C. Béghin,Patrick Canu,Erich Karkoschka,Christophe Sotin,Cesar Bertucci,William S. Kurth,Jean-Jacques Berthelier,R. Grard,Michel Hamelin,Konrad Schwingenschuh,Fernando Simões +10 more
TL;DR: In this article, Beghin et al. presented a thorough analysis of this signal based upon the Huygens probe attitude data deduced from the Descent Imager Spectral Radiometer (DISR) and relevant measurements obtained from the Radio Plasma Wave Science (RPWS) experiment and from the magnetometer (MAG) onboard Cassini orbiter during flybys of Titan.
Journal ArticleDOI
Electrostatic Potential Radiated by a Pulsating Charge in a Two‐Electron Temperature Plasma
TL;DR: In this paper, a numerical method is developed for the computation of the electrostatic potential in a sum of Maxwellian plasmas, and the results are used to build synthetic mutual impedance spectra and quantify the effect of a warm electron population on mutual impedance experiments, in order to illustrate how the method could be applied for recent and future planetary space missions.
