The past two decades have seen a major expansion in the availability, size, and precision of
time-domain data sets in astronomy. Owing to their unique combination of flexibility …

The rotation of a star and the revolutions of its planets are not necessarily aligned. This
article reviews the measurement techniques, key findings, and theoretical interpretations …

Planets with radii between that of the Earth and Neptune (hereafter referred to as 'sub-
Neptunes') are found in close-in orbits around more than half of all Sun-like stars,. However …

We demonstrate that the deep volatile storage capacity of magma oceans has significant
implications for the bulk composition, interior, and climate state inferred from exoplanet mass …

Planets intermediate in size between the Earth and Neptune, and orbiting closer to their host
stars than Mercury does the Sun, are the most common type of planet revealed by exoplanet …

The radius valley separating super-Earths from mini-Neptunes is a fundamental benchmark
for theories of planet formation and evolution. Observations show that the location of the …

Exoplanets transiting bright nearby stars are key objects for advancing our knowledge of
planetary formation and evolution. The wealth of photons from the host star gives detailed …

Aims. The catalog of Stars With ExoplanETs (SWEET-Cat) was originally introduced in 2013.
Since then many more exoplanets have been confirmed, increasing significantly the number …

ABSTRACT CHEOPS (CHaracterising ExOPlanet Satellite) is an ESA S-class mission that
observes bright stars at high cadence from low-Earth orbit. The main aim of the mission is to …

Within the first few hundreds of millions of years, many physical processes sculpt the
eventual properties of young planets. NASA's Transiting Exoplanet Survey Satellite (TESS) …
