Warm Saturn type exoplanets orbiting M-dwarfs are particularly suitable for in-depth cloud characterisation through transmission spectroscopy due to their favourable stellar to planetary radius contrast. However, modelling cloud formation consistentl

Aggregation and charging of mineral cloud particles under high-energy irradiation

Autor: Bach-Møller, Nanna, Helling, Christiane, Jørgensen, Uffe G., Enghoff, Martin B.

It is known from Earth that ionizing high-energy radiation can lead to ion-induced nucleation of cloud condensation nuclei in the atmosphere. Since the amount of high-energy radiation can vary greatly based on the radiative environment of a host star

Harnessing machine learning for accurate treatment of overlapping opacity species in general circulation models

Autor: Schneider, Aaron David, Mollière, Paul, Louppe, Gilles, Carone, Ludmila, Jørgensen, Uffe Gråe, Decin, Leen, Helling, Christiane

To understand high precision observations of exoplanets and brown dwarfs, we need detailed and complex general circulation models (GCMs) that incorporate hydrodynamics, chemistry, and radiation. For this study, we specifically examined the coupling b

The impact of the DART spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos' orbit substantially, largely from the ejection of material. We present results from twelve Earth-based facilities involved in a world-wide campaign to

We present an analysis of microlensing event OGLE-2019-BLG-0825. This event was identified as a planetary candidate by preliminary modeling. We find that significant residuals from the best-fit static binary-lens model exist and a xallarap effect can
