The dispersal of planet-forming discs: theory confronts observations
B Ercolano, I Pascucci - Royal Society Open Science, 2017 - royalsocietypublishing.org
Discs of gas and dust around million-year-old stars are a by-product of the star formation
process and provide the raw material to form planets. Hence, their evolution and dispersal …

[HTML][HTML] The nature of the TRAPPIST-1 exoplanets
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
The streaming instability (SI) is a mechanism to aerodynamically concentrate solids in
protoplanetary disks and trigger the formation of planetesimals. The SI produces strong …

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 …

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 …

The mass and size distribution of planetesimals formed by the streaming instability. I. The role of self-gravity
We study the formation of planetesimals in protoplanetary disks from the gravitational
collapse of solid over-densities generated via the streaming instability. To carry out these …

Concentrating small particles in protoplanetary disks through the streaming instability
Laboratory experiments indicate that direct growth of silicate grains via mutual collisions can
only produce particles up to roughly millimeters in size. On the other hand, recent …
