Measuring the metallicity and carbon-to-oxygen (C/O) ratio in exoplanet atmospheres is a
fundamental step towards constraining the dominant chemical processes at work and, if in …

Ultrahot giant exoplanets receive thousands of times Earth's insolation 1, 2. Their high-
temperature atmospheres (greater than 2,000 kelvin) are ideal laboratories for studying …

Population studies of exoplanets are key to unlocking their statistical properties. So far, the
inferred properties have been mostly limited to planetary, orbital, and stellar parameters …

We provide a database of transit times and updated ephemerides for 382 planets based on
data from the NASA Transiting Exoplanet Survey Satellite (TESS) and previously reported …

We present thermal phase curve measurements for the hot Jupiter WASP-103b observed
with Hubble/WFC3 and Spitzer/IRAC. The phase curves have large amplitudes and …

Here we present a publicly available database of opacities for molecules of astrophysical
interest named ExoMolOP that has been compiled for over 80 species, and is based on the …

We present analysis of the atmospheres of 70 gaseous extrasolar planets via transit
spectroscopy with Hubble's Wide Field Camera 3 (WFC3). For over half of these, we …

High-resolution optical spectroscopy is a powerful tool to characterise exoplanetary
atmospheres from the ground. The sodium D lines, with their large cross sections, are …

The ExoClock project is an inclusive, integrated, and interactive platform that was developed
to monitor the ephemerides of the Ariel targets to increase the mission efficiency. The project …

Many of the known hot Jupiters are formally unstable to tidal orbital decay. The only hot
Jupiter for which orbital decay has been directly detected is WASP-12, for which transit …
