Astrochemistry and compositions of planetary systems

KI Öberg, EA Bergin - Physics Reports, 2021‏ - Elsevier
Planets form and obtain their compositions in disks of gas and dust around young stars. The
chemical compositions of these planet-forming disks regulate all aspects of planetary …

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 …

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 …

Formation of planetary systems by pebble accretion and migration-How the radial pebble flux determines a terrestrial-planet or super-Earth growth mode

M Lambrechts, A Morbidelli, SA Jacobson… - Astronomy & …, 2019‏ - aanda.org
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 …

Compositional imprints in density–distance–time: a rocky composition for close-in low-mass exoplanets from the location of the valley of evaporation

S **, C Mordasini - The Astrophysical Journal, 2018‏ - iopscience.iop.org
We use an end-to-end model of planet formation, thermodynamic evolution, and
atmospheric escape to investigate how the statistical imprints of evaporation depend on the …

Evolution of the radius valley around low-mass stars from Kepler and K2

R Cloutier, K Menou - The Astronomical Journal, 2020‏ - iopscience.iop.org
We present calculations of the occurrence rate of small close-in planets around low-mass
dwarf stars using the known planet populations from the Kepler and K2 missions. Applying …

Make super-Earths, not Jupiters: Accreting nebular gas onto solid cores at 0.1 AU and beyond

EJ Lee, E Chiang, CW Ormel - The Astrophysical Journal, 2014‏ - iopscience.iop.org
Close-in super-Earths having radii 1–4 R⊕ may possess hydrogen atmospheres comprising
a few percent by mass of their rocky cores. We determine the conditions under which such …

Magma ocean, water, and the early atmosphere of Venus

A Salvador, G Avice, D Breuer, C Gillmann… - Space Science …, 2023‏ - Springer
The current state and surface conditions of the Earth and its twin planet Venus are drastically
different. Whether these differences are directly inherited from the earliest stages of …

Silicon isotope constraints on terrestrial planet accretion

IJ Onyett, M Schiller, GV Makhatadze, Z Deng… - Nature, 2023‏ - nature.com
Understanding the nature and origin of the precursor material to terrestrial planets is key to
