Lightning on exoplanets and brown dwarfs: Modelling and detection of lightning signatures throughout the electromagnetic spectrum [PDF]

open access: yesarXiv, 2021
Lightning is an important electrical phenomenon, known to exist in several Solar System planets. It carries information on convection and cloud formation, and may be important for pre-biotic chemistry. Exoplanets and brown dwarfs have been shown to host environments appropriate for the initiation of lightning discharges.
