Origins of hot Jupiters

RI Dawson, JA Johnson - Annual Review of Astronomy and …, 2018 - annualreviews.org
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 …

Atmospheres of rocky exoplanets

R Wordsworth, L Kreidberg - Annual Review of Astronomy and …, 2022 - annualreviews.org
Rocky planets are common around other stars, but their atmospheric properties remain
largely unconstrained. Thanks to a wealth of recent planet discoveries and upcoming …

Conclusive evidence for a population of water worlds around M dwarfs remains elusive

JG Rogers, HE Schlichting… - The Astrophysical Journal …, 2023 - iopscience.iop.org
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 California-Kepler survey. III. A gap in the radius distribution of small planets

BJ Fulton, EA Petigura, AW Howard… - The Astronomical …, 2017 - iopscience.iop.org
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 California-Kepler survey. VII. Precise planet radii leveraging Gaia DR2 reveal the stellar mass dependence of the planet radius gap

BJ Fulton, EA Petigura - The Astronomical Journal, 2018 - iopscience.iop.org
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 …

The evaporation valley in the Kepler planets

JE Owen, Y Wu - The Astrophysical Journal, 2017 - iopscience.iop.org
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 …

Sculpting the valley in the radius distribution of small exoplanets as a by-product of planet formation: the core-powered mass-loss mechanism

A Gupta, HE Schlichting - Monthly Notices of the Royal …, 2019 - academic.oup.com
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 …

An asteroseismic view of the radius valley: stripped cores, not born rocky

V Van Eylen, C Agentoft, MS Lundkvist… - Monthly Notices of …, 2018 - academic.oup.com
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 …

Evidence for the volatile-rich composition of a 1.5-Earth-radius planet

C Piaulet, B Benneke, JM Almenara, D Dragomir… - Nature …, 2023 - nature.com
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 …

Probabilistic forecasting of the masses and radii of other worlds

J Chen, D Kipping - The Astrophysical Journal, 2016 - iopscience.iop.org
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 …
