Clouds are ubiquitous in exoplanet atmospheres and represent a challenge for the model interpretation of their spectra. Complex cloud models are too numerically costly for generating a large number of spectra, while more efficient models may be too strongly simplified. We aim to constrain the atmospheric properties of the directly imaged planet HR 8799e with a free retrieval approach. We use our radiative transfer code petitRADTRANS for generating spectra, which we couple to the PyMultiNest… Expand
The composition of hot Jupiter atmospheres assembled within chemically evolved protoplanetary discs
The radial-dependent positions of snowlines of abundant oxygen- and carbon-bearing molecules in protoplanetary discs will result in systematic radial variations in the C/O ratios in the gas and ice.Expand
Moderate-resolution K-band Spectroscopy of Substellar Companion κ Andromedae b
We present moderate-resolution (R ~ 4000) K-band spectra of the "super-Jupiter," κ Andromedae b. The data were taken with the OSIRIS integral field spectrograph at Keck Observatory. The spectraExpand
The ExoGRAVITY project: using single mode interferometry to characterize exoplanets
Combining adaptive optics and interferometric observations results in a considerable contrast gain compared to single-telescope, extreme AO systems. Taking advantage of this, the ExoGRAVITY projectExpand
MIRACLES: atmospheric characterization of directly imaged planets and substellar companions at 4–5 μm
The circumstellar disk of PDS 70 hosts two forming planets, which are actively accreting gas from their environment. In this work, we report the first detection of PDS 70 b in the Br$\alpha$ and $M'$Expand
Star and planet formation with the new generation VLTI and CHARA beam combiners
The diversity of planetary systems discovered in recent years has reinforced the interest in the conditions of the formation of stars and their planetary systems. The new generation of imagingExpand
Direct confirmation of the radial-velocity planetβPictoris c
Methods used to detect giant exoplanets can be broadly divided into two categories: indirect and direct. Indirect methods are more sensitive to planets with a small orbital period, whereas directExpand
On-sky performance and recent results from the Subaru coronagraphic extreme adaptive optics system
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument on the Subaru telescope on Maunakea, Hawaii is continuing to advance its AO performance, delivering H band Strehl ratios in excess of 0.9 for bright stars. Expand
The TW Hya Rosetta Stone Project IV: A Hydrocarbon-rich Disk Atmosphere
Connecting the composition of planet-forming disks with that of gas giant exoplanet atmospheres, in particular through C/O ratios, is one of the key goals of disk chemistry. Small hydrocarbons likeExpand
Aerosols in Exoplanet Atmospheres
Observations of exoplanet atmospheres have shown that aerosols, like in the Solar System, are common across a variety of temperatures and planet types. The formation and distribution of theseExpand
Cloud busting: enstatite and quartz clouds in the atmosphere of 2M2224-0158
We present the most detailed data-driven exploration of cloud opacity in a substellar object to-date. We have tested over 60 combinations of cloud composition and structure, particle sizeExpand


Directly imaged exoplanets are unexplored laboratories for the application of the spectral and temperature retrieval method, where the chemistry and composition of their atmospheres are inferred fromExpand
A comparison of chemistry and dust cloud formation in ultracool dwarf model atmospheres
The atmospheres of substellar objects contain clouds of oxides, iron, silicates and other refractory condensates. Water clouds are expected in the coolest objects. The opacity of these 'dust' cloudsExpand
Neglected Clouds in T and Y Dwarf Atmospheres
As brown dwarfs cool, a variety of species condense in their atmospheres, forming clouds. Iron and silicate clouds shape the emergent spectra of L dwarfs, but these clouds dissipate at the L/TExpand
Unveiling cloudy exoplanets: the influence of cloud model choices on retrieval solutions
In recent years, it has become clear that a substantial fraction of transiting exoplanets have some form of aerosol present in their atmospheres. Transit spectroscopy – mostly of hot Jupiters, butExpand
