Density, not radius, separates rocky and water-rich small planets orbiting M dwarf stars

R Luque, E Pallé - Science, 2022‏ - science.org
Exoplanets smaller than Neptune are common around red dwarf stars (M dwarfs), with those
that transit their host star constituting the bulk of known temperate worlds amenable for …

Water in the terrestrial planet-forming zone of the PDS 70 disk

G Perotti, V Christiaens, T Henning, B Tabone… - Nature, 2023‏ - nature.com
Terrestrial and sub-Neptune planets are expected to form in the inner (less than 10 au)
regions of protoplanetary disks. Water plays a key role in their formation,–, although it is yet …

Architectures of compact multi-planet systems: diversity and uniformity

LM Weiss, SC Millholland, EA Petigura… - arxiv preprint arxiv …, 2022‏ - arxiv.org
One of the most important developments in exoplanet science in the past decade is the

Hints for a turnover at the snow line in the giant planet occurrence rate

RB Fernandes, GD Mulders, I Pascucci… - The Astrophysical …, 2019‏ - iopscience.iop.org
The orbital distribution of giant planets is crucial for understanding how terrestrial planets

Occurrence rates of planets orbiting FGK stars: Combining Kepler DR25, Gaia DR2, and Bayesian inference

DC Hsu, EB Ford, D Ragozzine… - The Astronomical …, 2019‏ - iopscience.iop.org
We characterize the occurrence rate of planets, ranging in size from 0.5 to 16 R⊕, orbiting
FGK stars with orbital periods from 0.5 to 500 days. Our analysis is based on results from …

The New Generation Planetary Population Synthesis (NGPPS)-I. Bern global model of planet formation and evolution, model tests, and emerging planetary systems
