Energetic neutral atom (ENA) and charged particle periodicities in Saturn’s magnetosphere

Paranicas, C.; Krimigis, Stamatios M.; Mitchell, Donald G. +2 more

The Magnetospheric Imaging Instrument (MIMI) on the Cassini spacecraft has observed energetic neutral atoms (ENA) and charged particles at Saturn from mid-2004 to the present. The particles often but not always reveal striking periodic behavior that seems to depend on the type of particle and spacecraft location. When subjected to a Lomb periodogr…
