Characterizing the atmospheres of extrasolar planets is the new frontier in exoplanetary
science. The last two decades of exoplanet discoveries have revealed that exoplanets are …

In addition to long-lived radioactive nuclei like U and Th isotopes, which have been used to
measure the age of theGalaxy, also radioactive nuclei with half-lives between 0.1 and 100 …

Planets form and obtain their compositions in dust-and gas-rich disks around young stars,
and the outcome of this process is intimately linked to the disk chemical properties. The …

High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

The composition of a planet's atmosphere is determined by its formation, evolution, and
present-day insolation. A planet's spectrum therefore may hold clues on its origins. We …

We propose a set of standard assumptions for the modelling of Class II and III protoplanetary
disks, which includes detailed continuum radiative transfer, thermo-chemical modelling of …

Many parameters constraining the spectral appearance of exoplanets are still poorly
understood. We therefore study the properties of irradiated exoplanet atmospheres over a …

Context. β Pictoris is arguably one of the most studied stellar systems outside of our own.
Some 30 yr of observations have revealed a highly-structured circumstellar disk, with rings …

Context. The James Webb Space Telescope will enable astronomers to obtain exoplanet
spectra of unprecedented precision. The MIRI instrument especially may shed light on the …

Context. The atmospheres of extrasolar planets are thought to be built largely through
accretion of pebbles and planetesimals. Such pebbles are also the building blocks of …
