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 ...

Exploring the Complex Ionization Environment of the Turbulent DM Tau Disk
The Astrophysical JournalIonization 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.

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 ...

Protoplanetary Disk Resonances and Type I Migration [PDF]
, 2011 Waves reflected by the inner edge of a protoplanetary disk are shown to significantly modify Type I migration, even allowing the trapping of planets near the inner disk edge for small planets in a range of disk parameters.

The Evidence of Radio Polarization Induced by the Radiative Grain Alignment and Self-scattering of Dust Grains in a Protoplanetary Disk [PDF]
, 2017 The mechanisms causing millimeter-wave polarization in protoplanetary disks are under debate. To disentangle the polarization mechanisms, we observe the protoplanetary disk around HL Tau at 3.1 mm with the Atacama Large Millimeter/submillimeter Array ...

FIRST DETECTION OF GAS-PHASE METHANOL IN A PROTOPLANETARY DISK [PDF]
, 2016 The first detection of gas-phase methanol in a protoplanetary disk (TW Hya) is presented. In addition to being one of the largest molecules detected in disks to date, methanol is also the first disk organic molecule with an unambiguous ice chemistry ...

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.

A Deep Search for Complex Organic Molecules toward the Protoplanetary Disk of V883 Ori
The Astronomical JournalComplex 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 ...
