Meteoric Ions Influence Conductance in the Jovian Ionosphere

by Viviane Pierrard 29 April 202225 April 2022

Meteoric ions dominate the Jovian lower ionosphere due to their long lifetimes. Due to the large densities of the meteoric ions, conductance is enhanced independently of local time.

New Energetic Neutral Atom Emissions from Jupiter, Io, and Europa

by Viviane Pierrard 15 June 202027 January 2022

The first Jovian off-equator Energetic Neutral Atom viewings reveal distinct emissions from Jupiter and the orbits of Io and Europa: Energetic particle injections surprisingly occur inside Io’s orbit.

Red and Green Aurora Stop and Go for Different Reasons

by Viviane Pierrard 5 July 20191 July 2019

Green-line arc is found to be embedded within large-scale upward field aligned currents while red-line-only arc is found to be associated with low-energy precipitation bursts.

Energetic Electrons Can Penetrate the Stratosphere

by Viviane Pierrard 17 October 2018

Precipitations of electrons with energies greater than 30 kiloelectron volts from the slot region penetrate at low altitude and can contribute to destroy ozone.
