High dust density in the midplane of protoplanetary disks is favorable for efficient grain
growth and can allow fast formation of planetesimals and planets, before disks dissipate …

Separating gas-giant and ice-giant planets by halting pebble accretion

M Lambrechts, A Johansen, A Morbidelli - Astronomy & Astrophysics, 2014 - aanda.org
In the solar system giant planets come in two flavours: gas giants (Jupiter and Saturn) with
massive gas envelopes, and ice giants (Uranus and Neptune) with much thinner envelopes …

The effect of gas drag on the growth of protoplanets-analytical expressions for the accretion of small bodies in laminar disks

CW Ormel, HH Klahr - Astronomy & Astrophysics, 2010 - aanda.org
Planetary bodies form by accretion of smaller bodies. It has been suggested that a very
efficient way to grow protoplanets is by accreting particles of size≪ km (eg, chondrules …

Planetesimal formation starts at the snow line

J Drążkowska, Y Alibert - Astronomy & Astrophysics, 2017 - aanda.org
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 …

Rapid coagulation of porous dust aggregates outside the snow line: a pathway to successful icy planetesimal formation

S Okuzumi, H Tanaka, H Kobayashi… - The Astrophysical …, 2012 - iopscience.iop.org
Rapid orbital drift of macroscopic dust particles is one of the major obstacles to planetesimal
formation in protoplanetary disks. We re-examine this problem by considering the porosity …

The New Generation Planetary Population Synthesis (NGPPS)-II. Planetary population of solar-like stars and overview of statistical results

A Emsenhuber, C Mordasini, R Burn, Y Alibert… - Astronomy & …, 2021 - aanda.org
Context. Planetary formation and evolution is a combination of multiple interlinked
processes. Constraining the mechanisms observationally requires statistical comparison to …

Hf–W–Th evidence for rapid growth of Mars and its status as a planetary embryo

N Dauphas, A Pourmand - Nature, 2011 - nature.com
Terrestrial planets are thought to have formed through collisions between large planetary
embryos of diameter∼ 1,000–5,000 km. For Earth, the last of these collisions involved an …

The formation of Jupiter by hybrid pebble–planetesimal accretion

Y Alibert, J Venturini, R Helled, S Ataiee, R Burn… - Nature …, 2018 - nature.com
The standard model for giant planet formation is based on the accretion of solids by a
growing planetary embryo, followed by rapid gas accretion once the planet exceeds a so …

On the water delivery to terrestrial embryos by ice pebble accretion

T Sato, S Okuzumi, S Ida - Astronomy & Astrophysics, 2016 - aanda.org
Standard accretion disk models suggest that the snow line in the solar nebula migrated
interior to the Earth's orbit in a late stage of nebula evolution. In this late stage, a significant …

Giant planet formation, evolution, and internal structure

R Helled, P Bodenheimer, M Podolak, A Boley… - arXiv preprint arXiv …, 2013 - arxiv.org
The large number of detected giant exoplanets offers the opportunity to improve our
understanding of the formation mechanism, evolution, and interior structure of gas giant …
