Ion escape from the upper ionosphere of Titan triggered by the solar wind
Lazar, M.; Moslem, W. M.; El-Labany, S. K. +3 more
The observed escape of ions from the ionosphere of Titan suggests a potential role of the solar wind in the interaction with the upper atmospheric layers. We investigate such a plausible scenario using a hydrodynamic fluid approach for the plasma expansion in the upper ionosphere of Titan, combining (Maxwellian) electrons and three different speci…
Rogue wave in Titan's atmosphere
Moslem, W. M.; El-Labany, S. K.; El-Bedwehy, N. A. +2 more
Rogue wave in a collisionless, unmagnetized electronegative plasma is investigated. For this purpose, the basic set of fluid equations is reduced to the Korteweg-de Vries (KdV) equation. However, when the frequency of the carrier wave is much smaller than the ion plasma frequency then the KdV equation is also used to study the nonlinear evolution …
Analysis of periodic orbits in the Saturn-Titan system using the method of Poincare section surfaces
Safiya Beevi, A.; Sharma, R. K.
We explore the periodic orbits and the regions of quasi-periodic motion around both the primaries in the Saturn-Titan system in the framework of planar circular restricted three-body problem. The location, nature and size of periodic and quasi-periodic orbits are studied using the numerical technique of Poincare surface of sections. The maximum am…
Quantifying the effect of finite field-of-view size on radiative transfer calculations of Titan's limb spectra measured by Cassini-CIRS
Irwin, P. G. J.; Teanby, N. A.
The Composite InfraRed Spectrometer (CIRS) on-board the Cassini spacecraft has currently returned around three years worth of data from Saturn's largest moon Titan. One of the unique aspects of CIRS is to take high spatial resolution spectra of the limb of Titan, with sub-scale height (20–40 km) resolutions. This is made possible by the small fiel…
Stochastic Acceleration of Energetic Particles in the Magnetosphere of Saturn
Martínez-Gómez, E.; Durand-Manterola, H. J.; Tejada, H. Pérez de
Voyager's plasma probe observations suggest that there are at least three fundamentally different plasma regimes in Saturn: the hot outer magnetosphere, the extended plasma sheet, and the inner plasma torus. At the outer regions of the inner torus some ions have been accelerated to reach energies of the order of 43 keV. We develop a model that cal…
