Can thermodynamic equilibrium be established in planet-forming disks?
Jayatee Kanwar, Peter Woitke, Inga Kamp +2
The inner regions of planet-forming disks are warm and dense. The chemical networks used for disk modelling so far were developed for a cold and dilute medium and do not include a…
Habitability constraints by nutrient availability in atmospheres of rocky exoplanets
Oliver Herbort, Peter Woitke, Christiane Helling +1
Life as we know it requires the presence of liquid water and the availability of nutrients, which are mainly based on the elements C, H, N, O, P, and S (CHNOPS) and trace metal mic…
Exploring terrestrial lightning parameterisations for exoplanets and brown dwarfs
G. Hodosán, Ch. Helling, I. Vorgul
Observations and models suggest that the conditions to develop lightning may be present in cloud-forming extrasolar planetary and brown dwarf atmospheres. Whether lightning on thes…
Clouds in Exoplanetary Atmospheres
Christiane Helling
Today, we know ~4330 exoplanets orbiting their host stars in ~3200 planetary systems. The diversity of these exoplanets is large, and none of the known exoplanets is a twin to any…
Coexistence of CH4, CO2 and H2O in exoplanet atmospheres
P. Woitke, O. Herbort, Ch. Helling +4
We propose a classification of exoplanet atmospheres based on their H, C, O, N element abundances below about 600 K. Chemical equilibrium models were run for all combinations of H,…
The Atmospheres of Rocky Exoplanets I. Outgassing of Common Rock and the Stability of Liquid Water
Oliver Herbort, Peter Woitke, Christiane Helling +1
Little is known about the interaction between atmospheres and crusts of exoplanets so far, but future space missions and ground-based instruments are expected to detect molecular f…
