Exoplanetary science is on the verge of an unprecedented revolution. The thousands of
exoplanets discovered over the past decade have most recently been supplemented by …

For the past 400 years, astronomers have sought to observe and interpret the Universe by
building more powerful telescopes. These incredible instruments extend the capabilities of …

Transmission spectroscopy,–of exoplanets has revealed signatures of water vapour,
aerosols and alkali metals in a few dozen exoplanet atmospheres,. However, these previous …

Abstract The James Webb Space Telescope (JWST) Early Release Observations (EROs) is
a set of public outreach products created to mark the end of commissioning and the …

We present the easy-to-use, publicly available, Python package petitRADTRANS, built for
the spectral characterization of exoplanet atmospheres. The code is fast, accurate, and …

Abstract The Transiting Exoplanet Survey Satellite (TESS) has a goal of detecting small
planets orbiting stars bright enough for mass determination via ground-based radial velocity …

Abstract The James Webb Space Telescope (JWST) will offer the first opportunity to
characterize terrestrial exoplanets with sufficient precision to identify high mean molecular …

We investigate a new class of habitable planets composed of water-rich interiors with
massive oceans underlying H 2-rich atmospheres, referred to here as Hycean worlds. With …

Nine transiting Earth-sized planets have recently been discovered around nearby late-M
dwarfs, including the TRAPPIST-1 planets and two planets discovered by the MEarth survey …

Stellar heating causes atmospheres of close-in exoplanets to expand and escape. These
extended atmospheres are difficult to observe because their main spectral signature …
