Prediction of sulphate hazes in the lower Venus atmosphere
Peter Woitke, Manuel Scherf, Christiane Helling +8
We study the amount, size distribution and material composition of (sub-)mic aerosol particles in the lower Venus atmosphere < 50 km. Our GGchem phase-equilibrium model predicts me…
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…
Cosmic ray ionisation of a post-impact early Earth atmosphere: Solar cosmic ray ionisation must be considered in origin-of-life scenarios
S. R. Raeside, D. Rodgers-Lee, P. B. Rimmer
Cosmic rays (CR), both solar and Galactic, have an ionising effect on the Earth's atmosphere and are thought to be important for prebiotic molecule production. In particular, the $…
Exploring the atmosphere of GJ 1132 b with CRIRES+
E. Palle, F. Yan, G. Morello +8
With a mass, radius, and mean density similar to Earth's, the rocky planet GJ 1132 b is the first truly small planet for which an atmosphere detection was proposed. If confirmed, u…
Kinetic and photochemical disequilibrium in the potentially carbon-rich atmosphere of the warm-Jupiter WASP-69b
Nidhi Bangera, Christiane Helling, Gloria Guilluy +5
High-resolution transmission spectroscopy of the warm gas-giant WASP-69b has revealed the presence of H2O, CO, CH4, NH3, and C2H2 in its atmosphere. This study investigates the imp…
MOVES IV. Modelling the influence of stellar XUV-flux, cosmic rays, and stellar energetic particles on the atmospheric composition of the hot Jupiter HD 189733b
Patrick Barth, Christiane Helling, Eva E. Stüeken +7
Hot Jupiters provide valuable natural laboratories for studying potential contributions of high-energy radiation to prebiotic synthesis in the atmospheres of exoplanets. In this fo…
