Exploring Enceladus's Interior Structure Using Electromagnetic Induction
Alexander Grayver, Joachim Saur
Electromagnetic (EM) sounding can constrain the electrical structure of Enceladus and, in turn, the salinity of its ocean and the porosity, fluid content, and thermal state of its…

Interaction of Trappist-1 exoplanets with coronal mass ejections: Joule heating, Poynting fluxes and the role of magnetic fields
Filip Elekes, Joachim Saur, Alexander Grayver
Flares and associated Coronal Mass Ejections (CMEs) are energetic stellar phenomena that shape the space weather around planets. Close-in exoplanets orbiting active cool stars are…

A decade of the fast-varying ionospheric and magnetospheric magnetic fields from ground and multi-satellite observations
Jingtao Min, Alexander Grayver
The time-varying geomagnetic field is a superposition of contributions from multiple internal and external current systems. A major source of geomagnetic variations at periods less…
