Lightning in other planets
Christiane Helling
More than 4000 planet are known that orbit stars other than our Sun. Many harbor a dynamic atmosphere that is cold enough that cloud particles can form in abundance. The diversity…
Atmospheric electrification in dusty, reactive gases in the solar system and beyond
Ch. Helling, R. G. Harrison, F. Honary +7
Detailed observations of the solar system planets reveal a wide variety of local atmospheric conditions. Astronomical observations have revealed a variety of extrasolar planets non…
Ionisation in atmospheres of brown dwarfs and extrasolar planets VI: Properties of large-scale discharge events
R. L. Bailey, Ch. Helling, G. Hodosán +2
Mineral clouds in substellar atmospheres play a special role as a catalyst for a variety of charge processes. If clouds are charged, the surrounding environment becomes electricall…
Electrostatic activation of prebiotic chemistry in substellar atmospheres
Craig R. Stark, Christiane Helling, Declan A. Diver +1
Charged dust grains in the atmospheres of exoplanets may play a key role in the formation of prebiotic molecules, necessary to the origin of life. Dust grains submerged in an atmos…
Ionization in Atmospheres of Brown Dwarfs and Extrasolar Planets V: Alfvén Ionization
Craig R. Stark, Christiane Helling, Declan A. Diver +1
Observations of continuous radio and sporadic X-ray emission from low-mass objects suggest they harbour localized plasmas in their atmospheric environments. For low-mass objects, t…
Ionisation in atmospheres of Brown Dwarfs and extrasolar planets I The role of electron avalanche
Ch. Helling, M. Jardine, S. Witte +1
Brown Dwarf and extrasolar planet atmospheres form clouds which strongly influence the local chemistry and physics. These clouds are globally neutral obeying dust-gas charge equili…
