From atmospheric to exoplanet formation retrievals

, 2021
With new and upcoming observing facilities (JWST and the ELTs), the exoplanet community is poised to precisely measure the chemical inventory of exoplanet atmospheres.

Exoplanet Atmospheric Studies At High Spectral Resolution

, 2020
The study of exoplanet atmospheres is essential to understand the formation, evolution and composition of exoplanets. When a planet pass between its host star and an observer, a fraction of the star-light is absorbed by its atmosphere, thus revealing its

BOWIE-ALIGN: A JWST comparative survey of aligned vs misaligned hot Jupiters to test the dependence of atmospheric composition on migration history

RAS Techniques and Instruments
A primary objective of exoplanet atmosphere characterisation is to learn about planet formation and evolution, however, this is challenged by degeneracies.

Implications of magma oceans for astrophysical observations: mass-radius and atmospheric composition

, 2020
The earliest secondary atmosphere of a rocky planet originates from extensive volatile release during one or more magma ocean epochs that occur during and after the assembly of the planet.

The atmospheric composition of the ultra-hot Jupiter WASP-178 b observed with ESPRESSO

Astronomy & Astrophysics
Ultra-hot Jupiters (UHJ) have emerged as ideal testbeds for new techniques for studying exoplanet atmospheres. Only a limited number of them are currently well studied, however.

The effects of terrestrial exoplanet bulk composition on long-term planetary evolution

, 2020
With more observations of terrestrial exoplanets becoming available every year, the importance of geodynamical studies focusing on exoplanets is increasing. We know from observations that stellar chemical abundances vary in the Solar neighbourhood, which

A Machine Learning–ready Data Set for Exoplanet Atmospheric Retrieval

Astrophysical Journal Supplement Series
Atmospheric retrieval is a modeling technique used to determine a planet’s atmosphere’s temperature and composition from spectral data. The retrieved atmospheric composition can provide understanding into the surface fluxes of gaseous species necessary ...

A secondary atmosphere on the rocky Exoplanet 55 Cancri e.

Nature
Characterizing rocky exoplanets is a central endeavor of astronomy, and yet the search for atmospheres on rocky exoplanets has hitherto resulted in either tight upper limits on the atmospheric mass1-3 or inconclusive results4-6.

A benchmark JWST near-infrared spectrum for the exoplanet WASP-39 b

Nature Astronomy
Observing exoplanets through transmission spectroscopy supplies detailed information about their atmospheric composition, physics and chemistry. Before the James Webb Space Telescope (JWST), these observations were limited to a narrow wavelength range ...
