3D global multi-species Hall-MHD simulation of the Cassini T9 flyby
[1] The wake region of Titan is an important component of Titan’s interaction with its surrounding plasma and therefore a thorough understanding of its formation and structure is of primary interest. The Cassini spacecraft passed through the distant downstream region of Titan on 18:59:30 UT Dec. 26, 2005, which is referred to as the T9 flyby and provided a great opportunity to test our understa...
متن کاملStructure of Titan’s mid-range magnetic tail: Cassini magnetometer observations during the T9 flyby
[1] We analyze the magnetic structure of Titan’s mid-range magnetic tail (5–6 Titan radii downstream from the moon) during Cassini’s T9 flyby. Cassini magnetometer (MAG) measurements reveal a well-defined, induced magnetic tail consisting of two lobes and a distinct central current sheet. MAG observations also indicate that Saturn’s background magnetic field is close to the moon’s orbital plane...
متن کاملTime-dependent global MHD simulations of Cassini T32 flyby: From magnetosphere to magnetosheath
[1] When the Cassini spacecraft flew by Titan on 13 June 2007, at 13.6 Saturn local time, Titan was directly observed to be outside Saturn0s magnetopause. Cassini observations showed dramatic changes of magnetic field orientation as well as other plasma flow parameters during the inbound and outbound segments. In this paper, we study Titan’s ionospheric responses to such a sudden change in the ...
متن کاملCharged particle environment of Titan during the T9 flyby
[1] The ion measurements of the Cassini Plasma Spectrometer are presented which were acquired on 26 December 2005, during the T9 flyby at Titan. The plasma flow and magnetic field directions in the distant plasma environment of the moon were distinctly different from the other flybys. The near-Titan environment, dominated by ions of Titan origin, had a split signature, each with different ion c...
متن کاملMulti-scale Hall-MHD turbulence in the solar wind
Solar wind magnetic fluctuation spectra exhibit a significant power law steepening at frequencies f > 1Hz. The origin of this multi-scaling is investigated through dispersive Hall magnetohydrodynamics. We perform three-dimensional numerical simulations in the framework of a highly turbulent shell model and show that the large-scale magnetic fluctuations are characterized by a k– type spectrum w...
