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 …

Planets are expected to conclude their growth through a series of giant impacts: energetic,
global events that significantly alter planetary composition and evolution. Computer models …

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 …

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 characterization of exoplanets and their birth protoplanetary disks has enormously
advanced in the last decade. Benefitting from that, our global understanding of the planet …

The radius distribution of small, close-in exoplanets has recently been shown to be bimodal.
The photoevaporation model predicted this bimodality. In the photoevaporation scenario …

Super-Earths–planets with sizes between the Earth and Neptune–are found in tighter orbits
than that of the Earth around more than one third of main sequence stars. It has been …

The size frequency distribution of exoplanet radii between 1 and 4R⊕ is bimodal with peaks
at∼ 1.4 R⊕ and∼ 2.4 R⊕, and a valley at∼ 1.8 R⊕. This radius valley separates two …

Context. Observations have revealed in the Kepler data a depleted region separating
smaller super-Earths from larger sub-Neptunes. This can be explained as an evaporation …

The system of two transiting Neptune-sized planets around the bright, young M-dwarf AU
Mic provides a unique opportunity to test models of planet formation, early evolution, and …
