Forming planets via pebble accretion

A Johansen, M Lambrechts - Annual Review of Earth and …, 2017 - annualreviews.org
The detection and characterization of large populations of pebbles in protoplanetary disks
have motivated the study of pebble accretion as a driver of planetary growth. This review …

Dust evolution and the formation of planetesimals

T Birnstiel, M Fang, A Johansen - Space Science Reviews, 2016 - Springer
The solid content of circumstellar disks is inherited from the interstellar medium: dust
particles of at most a micrometer in size. Protoplanetary disks are the environment where …

[HTML][HTML] The nature of the TRAPPIST-1 exoplanets

SL Grimm, BO Demory, M Gillon, C Dorn… - Astronomy & …, 2018 - aanda.org
Context. The TRAPPIST-1 system hosts seven Earth-sized, temperate exoplanets orbiting an
ultra-cool dwarf star. As such, it represents a remarkable setting to study the formation and …

Thresholds for particle clumping by the streaming instability

R Li, AN Youdin - The Astrophysical Journal, 2021 - iopscience.iop.org
The streaming instability (SI) is a mechanism to aerodynamically concentrate solids in
protoplanetary disks and trigger the formation of planetesimals. The SI produces strong …

Origin of water in the inner Solar System: Planetesimals scattered inward during Jupiter and Saturn's rapid gas accretion

SN Raymond, A Izidoro - Icarus, 2017 - Elsevier
There is a long-standing debate regarding the origin of the terrestrial planets' water as well
as the hydrated C-type asteroids. Here we show that the inner Solar System's water is a …

Growth of asteroids, planetary embryos, and Kuiper belt objects by chondrule accretion

A Johansen, MMM Low, P Lacerda, M Bizzarro - Science Advances, 2015 - science.org
Chondrules are millimeter-sized spherules that dominate primitive meteorites (chondrites)
originating from the asteroid belt. The incorporation of chondrules into asteroidal bodies …

Pebble-isolation mass: Scaling law and implications for the formation of super-Earths and gas giants

B Bitsch, A Morbidelli, A Johansen, E Lega… - Astronomy & …, 2018 - aanda.org
The growth of a planetary core by pebble accretion stops at the so-called pebble isolation
mass, when the core generates a pressure bump that traps drifting pebbles outside its orbit …

The growth of planets by pebble accretion in evolving protoplanetary discs

B Bitsch, M Lambrechts, A Johansen - Astronomy & Astrophysics, 2015 - aanda.org
The formation of planets depends on the underlying protoplanetary disc structure, which in
turn influences both the accretion and migration rates of embedded planets. The disc itself …

Evidence of fast pebble growth near condensation fronts in the HL Tau protoplanetary disk

K Zhang, GA Blake, EA Bergin - The Astrophysical Journal …, 2015 - iopscience.iop.org
Water and simple organic molecular ices dominate the mass of solid materials available for
planetesimal and planet formation beyond the water snow line. Here we analyze ALMA long …
