Schumann Resonances As A Tool To Constrain The Depth Of Titan’s Buried Water Ocean
Among the lines of evidence for a buried ocean on Titan is the possible detection, in 2005, by the Permittivity, Wave and Altimetry (PWA) analyzer on board the ESA Huygens […]

MHD Simulations of the Space Weather in Proxima b: Habitability Conditions and Radio Emission
The habitability of exoplanets hosted by M-dwarf stars dramatically depends on their space weather. We present 3D magneto-hydrodynamic simulations to characterise the magneto-plasma environment and thus the habitability of the […]

Properties of Electrons Accelerated by the Ganymede-magnetosphere Interaction: Survey of Juno High-latitude Observations
The encounter between the Jovian co-rotating plasma and Ganymede gives rise to electromagnetic waves that propagate along the magnetic field lines and accelerate particles by resonant or non-resonant wave-particle interaction. […]

Exoplanet Magnetic Fields
Planetary magnetic fields are important indicators of planetary processes and evolution, from a planet’s outer core to its surface (if it possesses one) to its atmosphere and near-space environment.
