Dynamic mineral clouds on HD 189733b [PDF]
Astronomy & Astrophysics, 2017 Context. As the 3D spatial properties of exoplanet atmospheres are being observed in increasing detail by current and new generations of telescopes, the modelling of the 3D scattering effects of cloud forming atmospheres with inhomogeneous opacity structures becomes increasingly important to interpret observational data. Aims.

Atmospheric dynamics on tidally locked Earth-like planets in the habitable zone of an M dwarf star
Proceedings of the International Astronomical Union, 2013 We investigated the large scale atmospheric circulation of Gl581g, a potentially habitable planet around an M dwarf star, using an idealized dry global circulation model (GCM) with simplified thermal forcing as a first step towards a systematic extended ...

Boundary Layers of Circumplanetary Disks around Spinning Planets. I. Effects of Rossby Waves
The Astrophysical Journal, 2023 Gas giant planets are believed to accrete from their circumplanetary disks (CPDs). The CPDs usually involve accretion through the boundary layer (BL) in the vicinity of planets. Prior studies have concentrated on the BL of nonspinning planets.

Modelling dynamically driven global cloud formation microphysics in the HAT-P-1b atmosphere [PDF]
, 2023 Insight into the formation and global distribution of cloud particles in exoplanet atmospheres continues to be a key problem to tackle going into the JWST era. Understanding microphysical cloud processes and atmospheric feedback mechanisms in 3D has proven to be a challenging prospect for exoplaneteers.

An Observational Diagnostic for Distinguishing between Clouds and Haze in Hot Exoplanet Atmospheres [PDF]
, 2017 The nature of aerosols in hot exoplanet atmospheres is one of the primary vexing questions facing the exoplanet field. The complex chemistry, multiple formation pathways, and lack of easily identifiable spectral features associated with aerosols make it ...

HIGH RESOLUTION TRANSMISSION SPECTROSCOPY AS A DIAGNOSTIC FOR JOVIAN EXOPLANET ATMOSPHERES: CONSTRAINTS FROM THEORETICAL MODELS [PDF]
, 2014 We present high resolution transmission spectra of giant planet atmospheres from a coupled three-dimensional (3D) atmospheric dynamics and transmission spectrum model that includes Doppler shifts which arise from winds and planetary motion.
