Forming planetesimals in solar and extrasolar nebulae

E Chiang, AN Youdin - Annual Review of Earth and Planetary …, 2010 - annualreviews.org
Planets are built from planetesimals: solids larger than a kilometer that grow by colliding in
pairs. Planetesimals themselves are unlikely to form by two-body collisions alone; …

Observed properties of extrasolar planets

AW Howard - Science, 2013 - science.org
Observational surveys for extrasolar planets probe the diverse outcomes of planet formation
and evolution. These surveys measure the frequency of planets with different masses, sizes …

California legacy survey. II. Occurrence of giant planets beyond the ice line

BJ Fulton, LJ Rosenthal, LA Hirsch… - The Astrophysical …, 2021 - iopscience.iop.org
We used high-precision radial velocity measurements of FGKM stars to determine the
occurrence of giant planets as a function of orbital separation spanning 0.03–30 au. Giant …

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
form and predicting yields of exoplanet surveys. Here, we derive giant planets occurrence …

Extreme Water Loss and Abiotic O2 Buildup on Planets Throughout the Habitable Zones of M Dwarfs

R Luger, R Barnes - Astrobiology, 2015 - liebertpub.com
We show that terrestrial planets in the habitable zones of M dwarfs older than∼ 1 Gyr could
have been in runaway greenhouses for several hundred million years following their …

Prevalence of Earth-size planets orbiting Sun-like stars

EA Petigura, AW Howard… - Proceedings of the …, 2013 - National Acad Sciences
Determining whether Earth-like planets are common or rare looms as a touchstone in the
question of life in the universe. We searched for Earth-size planets that cross in front of their …

Breaking the chains: hot super-Earth systems from migration and disruption of compact resonant chains

A Izidoro, M Ogihara, SN Raymond… - Monthly Notices of …, 2017 - academic.oup.com
Abstract 'Hot super-Earths'(or 'mini-Neptunes') between one and four times Earth's size with
period shorter than 100 d orbit 30–50 per cent of Sun-like stars. Their orbital configuration …

Planet occurrence within 0.25 AU of solar-type stars from Kepler

AW Howard, GW Marcy, ST Bryson… - The Astrophysical …, 2012 - iopscience.iop.org
We report the distribution of planets as a function of planet radius, orbital period, and stellar
effective temperature for orbital periods less than 50 days around solar-type (GK) stars …

The exoplanet radius valley from gas-driven planet migration and breaking of resonant chains

A Izidoro, HE Schlichting, A Isella… - The Astrophysical …, 2022 - iopscience.iop.org
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 …

Photoevaporation and high-eccentricity migration created the sub-Jovian desert

JE Owen, D Lai - Monthly Notices of the Royal Astronomical …, 2018 - academic.oup.com
The mass–period or radius–period distribution of close-in exoplanets shows a paucity of
intermediate mass/size (sub-Jovian) planets with periods≲ 3 d. We show that this sub …
