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…
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 III. Breakdown conditions for mineral clouds
Ch. Helling, M. Jardine, C. Stark +1
Electric discharges were detected directly in the cloudy atmospheres of Earth, Jupiter and Saturn, are debatable for Venus, and indirectly inferred for Neptune and Uranus in our so…
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…
