On the Evolution of Dust Mineralogy, From Protoplanetary Disks to Planetary Systems [PDF]

, 2011
Mineralogical studies of silicate features emitted by dust grains in protoplanetary disks and Solar System bodies can shed light on the progress of planet formation.

Exploring the Complex Ionization Environment of the Turbulent DM Tau Disk

The Astrophysical Journal
Ionization drives important chemical and dynamical processes within protoplanetary disks, including the formation of organics and water in the cold midplane and the transportation of material via accretion and magnetohydrodynamic flows.

Magma Ocean Evolution at Arbitrary Redox State

Journal of Geophysical Research: Planets, Volume 129, Issue 12, December 2024.
Abstract Interactions between magma oceans and overlying atmospheres on young rocky planets leads to an evolving feedback of outgassing, greenhouse forcing, and mantle melt fraction. Previous studies have predominantly focused on the solidification of oxidized Earth‐similar planets, but the diversity in mean density and irradiation observed in the low ...

Dust Size Growth and Settling in a Protoplanetary Disk

, 2006
We have studied dust evolution in a quiescent or turbulent protoplanetary disk by numerically solving coagulation equation for settling dust particles, using the minimum mass solar nebular model.

A Deep Search for Complex Organic Molecules toward the Protoplanetary Disk of V883 Ori

The Astronomical Journal
Complex organic molecules (COMs) in the form of prebiotic molecules are potential building blocks of life. Using Atacama Large Millimeter/submillimeter Array Band 7 observations in spectral scanning mode, we carried out a deep search for COMs within the ...

Differences in elemental abundances between CI chondrites and the solar photosphere

Meteoritics &Planetary Science, Volume 59, Issue 12, Page 3193-3214, December 2024.
Abstract CI chondrites have been a proxy for the solar system since the mid‐20th century. The photospheric and CI chondrite abundances (P and CI, respectively) show a strong correlation. CI as a proxy is also justified by the (i) smoothness of their abundances plotted as a function of odd mass number and (ii) agreement within the error of P as ...

The Determination of Protoplanetary Disk Masses [PDF]

, 2017
In this article we review the methods used to determine the gas and dust masses of protoplanetary disks, with an emphasis on the lesser characterized total gas mass. Our review encompasses all the indirect tracers and the methodology that is be used to isolate the hidden H2 via dust, CO, and HD emission.

Formation and evolution of the protoplanetary disk [PDF]

A disk formation model during collapse of the protosolar nebula, yielding a low-mass protoplanetary disk is presented. The following subject areas are covered: (1) circumstellar disks; (2) conditions for the formation of stars with disks; (3) early ...

Detectability of giant planets in protoplanetary disks by CO emission lines

, 2010
In this paper we intend to provide an indirect method to detect Jovian planets by studying near infrared emission spectra originating in the protoplanetary disks around T Tauri stars.
