Vanadium oxide clusters in substellar atmospheres: A quantum chemical study
Helena Lecoq-Molinos, David Gobrecht, J. P. Sindel +2
We aim to understand the formation of cloud condensation nuclei in oxygen-rich substellar atmospheres by calculating fundamental properties of the energetically most favorable vana…
Fully time-dependent cloud formation from a non-equilibrium gas-phase in exoplanetary atmospheres
Sven Kiefer, Helena Lecoq-Molinos, Christiane Helling +2
Recent observations suggest the presence of clouds in exoplanet atmospheres but have also shown that certain chemical species in the upper atmosphere might not be in chemical equil…
Infrared spectra of TiO2 clusters for hot Jupiter atmospheres
J. P. Sindel, Ch. Helling, D. Gobrecht +2
Context. Clouds seem unavoidable in cool and dense environments, and hence, are necessary to explain observations of exoplanet atmospheres, most recently of WASP 96b with JWST. Und…
The effect of thermal non-equilibrium on kinetic nucleation
Sven Kiefer, David Gobrecht, Leen Decin +1
Nucleation is considered to be the first step in dust and cloud formation in the atmospheres of asymptotic giant branch (AGB) stars, exoplanets, and brown dwarfs. In these environm…
Revisiting fundamental properties of TiO nanoclusters as condensation seeds in astrophysical environments
J. P. Sindel, D. Gobrecht, Ch. Helling +1
The formation of inorganic cloud particles takes place in several atmospheric environments including those of warm, hot, rocky and gaseous exoplanets, brown dwarfs, and AGB stars.…
Cloud formation in Exoplanetary Atmospheres
Christiane Helling
This invited review for young researchers presents key ideas on cloud formation as key part for virtual laboratories for exoplanet atmospheres. The basic concepts are presented, fo…
Dust in brown dwarfs and extra-solar planets. VIII. TiO seed formation: 3D Monte Carlo versus kinetic approach
C. Köhn, Ch. Helling, M. Bødker Enghoff +4
We aim to understand the onset of cloud formation {and study the formation of} TiO-CCNs. The formation of (TiO) clusters as precursors to extrasolar cloud formati…
