Disk evolution, element abundances and cloud properties of young gas giant planets

C Helling, P Woitke, PB Rimmer, I Kamp, WF Thi… - Life, 2014 - mdpi.com
We discuss the chemical pre-conditions for planet formation, in terms of gas and ice
abundances in a protoplanetary disk, as function of time and position, and the resulting …

Chemical diversity in protoplanetary disks and its impact on the formation history of giant planets

E Pacetti, D Turrini, E Schisano, S Molinari… - The Astrophysical …, 2022 - iopscience.iop.org
Giant planets can interact with multiple and chemically diverse environments in
protoplanetary disks while they form and migrate to their final orbits. The way this interaction …

Chemistry in an evolving protoplanetary disk: effects on terrestrial planet composition

J Moriarty, N Madhusudhan… - The Astrophysical …, 2014 - iopscience.iop.org
The composition of planets is largely determined by the chemical and dynamical evolution of
the disk during planetesimal formation and growth. To predict the diversity of exoplanet …

planetary atmospheres based on the cumulative gaseous chemical species that are …

Formation of gas and ice giant planets

AP Boss - Earth and Planetary Science Letters, 2002 - Elsevier
Agreement about planetary formation processes deteriorates sharply with distance from the
Sun. While the terrestrial planets are widely believed to have formed from the collisional …

SimAb: A simple, fast, and flexible model to assess the effects of planet formation on the atmospheric composition of gas giants

N Khorshid, M Min, JM Désert, P Woitke… - Astronomy & …, 2022 - aanda.org

formation scenario. Conversely, planet formation processes shape the composition of …

Formation of secondary atmospheres on terrestrial planets by late disk accretion

Q Kral, J Davoult, B Charnay - Nature Astronomy, 2020 - nature.com
Recently, gas disks have been discovered around main-sequence stars well beyond the
usual protoplanetary disk lifetimes (that is,≳ 10 Myr), when planets have already formed …

Excess C/O and C/H in outer protoplanetary disk gas

KI Öberg, EA Bergin - The Astrophysical Journal Letters, 2016 - iopscience.iop.org
The compositions of nascent planets depend on the compositions of their birth disks. In

Molecular abundances and C/O ratios in chemically evolving planet-forming disk midplanes

C Eistrup, C Walsh, EF van Dishoeck - Astronomy & Astrophysics, 2018 - aanda.org
Context. Exoplanet atmospheres are thought be built up from accretion of gas as well as
pebbles and planetesimals in the midplanes of planet-forming disks. The chemical …
