Hot Jupiters were the first exoplanets to be discovered around main sequence stars and
astonished us with their close-in orbits. They are a prime example of how exoplanets have …

Rocky planets are common around other stars, but their atmospheric properties remain
largely unconstrained. Thanks to a wealth of recent planet discoveries and upcoming …

The population of small, close-in exoplanets is bifurcated into super-Earths and sub-
Neptunes. We calculate physically motivated mass–radius relations for sub-Neptunes, with …

The size of a planet is an observable property directly connected to the physics of its
formation and evolution. We used precise radius measurements from the California-Kepler …

The distribution of planet sizes encodes details of planet formation and evolution. We
present the most precise planet size distribution to date based on Gaia parallaxes, Kepler …

A new piece of evidence supporting the photoevaporation-driven evolution model for low-
mass, close-in exoplanets was recently presented by the California–Kepler Survey. The …

Recent observations revealed a bimodal radius distribution of small, short-period exoplanets
with a paucity in their occurrence, a radius 'valley', around 1.5–2.0 R⊕. In this work, we …

Various theoretical models treating the effect of stellar irradiation on planetary envelopes
predict the presence of a radius valley, ie a bimodal distribution of planet radii, with super …

The population of planets smaller than approximately 1.7 Earth radii (R⊕) is widely
interpreted as consisting of rocky worlds, generally referred to as super-Earths. This picture …

Mass and radius are two of the most fundamental properties of an astronomical object.
Increasingly, new planet discoveries are being announced with a measurement of one of …
