摘要： From a re-examination of the trajectories of small charged grains in the vicinity of the Saturnian rings, it is shown that the orbital motion of positively charged grains with a charge-to-mass ratio on the order of 10 super(-6) e amu super(-1) could allow the injection of water material into the equatorial atmosphere. Thus, a mechanism of ionospheric depletion in the equatorial region is provided, as indicated by the Cassini radio occultation measurements. 出版者： United States 出版日期： 2014-05-01 出處： The Astrophysical journal, 2014-05, Vol.786 (1), p.34-8 資源來源： Institute of Physics Journals 識別號： ISSN: 0004-637X 識別號： ISSN: 1538-4357 識別號： EISSN: 1538-4357 識別號： DOI: 10.1088/0004-637X/786/1/34
