Dust in brown dwarfs and extra-solar planets V. Cloud formation in carbon- and oxygen-rich environment
Ch. Helling, D. Tootill, P. Woitke +1
Recent observations indicate potentially carbon-rich exoplanet atmospheres. Spectral fitting methods for brown dwarfs and exoplanets have invoked the C/O ratio as additional parame…
Lightning climatology of exoplanets and brown dwarfs guided by Solar System data
Gabriella Hodosán, Christiane Helling, Rubén Asensio-Torres +2
Clouds form on extrasolar planets and brown dwarfs where lightning could occur. Lightning is a tracer of atmospheric convection, cloud formation and ionization processes as known f…
Is lightning a possible source of the radio emission on HAT-P-11b?
Gabriella Hodosán, Paul B. Rimmer, Christiane Helling
Lightning induced radio emission has been observed on Solar system planets. There have been many attempts to observe exoplanets in the radio wavelength, however, no unequivocal det…
Flash ionisation signature in coherent cyclotron emission from Brown Dwarfs
Irena Vorgul, Christiane Helling
Brown dwarfs form mineral clouds in their atmospheres, where charged particles can produce large-scale discharges in form of lightning resulting in a substantial sudden increase of…
