Dust evolution and the formation of planetesimals
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 …

Dust-to-gas and refractory-to-ice mass ratios of comet 67P/Churyumov-Gerasimenko from Rosetta observations
This chapter reviews the estimates of the dust-to-gas and refractory-to-ice mass ratios
derived from Rosetta measurements in the lost materials and the nucleus of 67P/Churyumov …

A steeper than linear disk mass–stellar mass scaling relation
The disk mass is among the most important input parameter for every planet formation
model to determine the number and masses of the planets that can form. We present an …

Planet formation theory in the era of ALMA and Kepler: from pebbles to exoplanets
Our understanding of planet formation has been rapidly evolving in recent years. The

CO depletion in protoplanetary disks: a unified picture combining physical sequestration and chemical processing
The gas-phase CO abundance (relative to hydrogen) in protoplanetary disks decreases by
up to two orders of magnitude from its interstellar medium value of∼ 10− 4, even after …

Sintering-induced dust ring formation in protoplanetary disks: Application to the HL tau disk
The latest observation of HL Tau by ALMA revealed spectacular concentric dust rings in its
circumstellar disk. We attempt to explain the multiple ring structure as a consequence of …

Planetesimal formation starts at the snow line
Context. The formation stage of planetesimals represents a major gap in our understanding
of the planet formation process. Late-stage planet accretion models typically make arbitrary …

Planetesimal formation near the snowline: in or out?
D Schoonenberg, CW Ormel - Astronomy & Astrophysics, 2017 - aanda.org
Context. The formation of planetesimals in protoplanetary disks is not well-understood.
Streaming instability is a promising mechanism to directly form planetesimals from pebble …

Close-in planetesimal formation by pile-up of drifting pebbles
Context. The consistency of planet formation models suffers from the disconnection between
the regime of small and large bodies. This is primarily caused by so-called growth barriers …
