Energetic neutral atom emissions from Titan interaction with Saturn's magnetosphere.
The Cassini Magnetospheric Imaging Instrument (MIMI) observed the interaction of Saturn's largest moon, Titan, with Saturn's magnetosphere during two close flybys of Titan on 26 October and 13 December 2004. The MIMI Ion and Neutral Camera (INCA) continuously imaged the energetic neutral atoms (ENAs) generated by charge exchange reactions between the energetic, singly ionized trapped magnetosph...
متن کاملThe NUADU experiment on TC-2 and the first Energetic Neutral Atom (ENA) images recorded by this instrument
The Earth’s ring current and how it responds to varying interplanetary conditions is described and an account provided of the production of Energetic Neutral Atoms (ENAs) in the geo-corona. Also, the potential to remotely monitor, on a global scale, the temporal and spatial evolution of magnetospheric plasma populations through analysing ENA images recorded during magnetic storms/substorms is i...
متن کاملEnergetic neutral atom response to solar wind dynamic pressure enhancements
[1] We have investigated the response of the ring current to solar wind dynamic pressure (Pdyn) enhancement impacts on the magnetosphere by using energetic neutral atom (ENA) images obtained by the High-Energy Neutral Atom (HENA) imager on board the IMAGE spacecraft. In this work we present several events by distinguishing between pressure events where only the pure compression effects exist (w...
متن کاملEnergetic neutral atom fluxes from the heliosheath varying with the activity phase of the solar cycle
Energetic neutral atoms (ENA’s) which are produced in the heliospheric interface can be used to remotely investigate this highly interesting, but poorly known region acting as buffer against the interstellar plasma. To optimally take advantage from this very promising observational technique, based on ENA flux measurements, one needs to know the spectral production rate of the ENA’s in the heli...
متن کاملSeparation of the Interstellar Boundary Explorer Ribbon from Globally Distributed Energetic Neutral Atom Flux
The Interstellar Boundary Explorer (IBEX) observes a remarkable feature, the IBEX ribbon, which has energetic neutral atom (ENA) flux over a narrow region ∼20◦ wide, a factor of 2–3 higher than the more globally distributed ENA flux. Here, we separate ENA emissions in the ribbon from the distributed flux by applying a transparency mask over the ribbon and regions of high emissions, and then sol...
