Consistent Dust and Gas Models for Protoplanetary Disks. III. Models for Selected Objects from the FP7 DIANA Project [PDF]

Publications of the Astronomical Society of the Pacific, 2018
The European FP7 project DIANA has performed a coherent analysis of a large set of observational data of protoplanetary disks by means of thermo-chemical disk models.

Metallic messengers from the cosmos: Rare (Al,Cu)‐bearing meteorites from the Project Stardust collection

Meteoritics &Planetary Science, Volume 60, Issue 7, Page 1609-1620, July 2025.
Abstract We report the discovery of (Al,Cu)‐bearing metallic alloys in two micrometeorites found in the Project Stardust collection gathered from urban rooftop environments in Norway. Most of the alloys are the same as those found in the Khatyrka meteorite and other micrometeorites, though one has a composition that has not been reported previously ...

The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO). XI. Beam-corrected Gas Disk Sizes from Fitting 12CO Moment Zero Maps

The Astrophysical Journal
The inward drift of millimeter–centimeter sized pebbles in protoplanetary disks has become an important part of our current theories of planet formation and, more recently, planet composition as well.

Dust Coagulation Reconciles Protoplanetary Disk Observations with the Vertical Shear Instability. I. Dust Coagulation and the VSI Dead Zone

The Astrophysical Journal, 2023
Protoplanetary disks exhibit a vertical gradient in angular momentum, rendering them susceptible to the vertical shear instability (VSI). The most important condition for the onset of this mechanism is a short timescale of thermal relaxation (≲0.1 ...

GoFish: Fishing for Line Observations in Protoplanetary Disks

Journal of Open Source Software, 2019
Molecular line observations are an essential complement to high resolution continuum data when studying the planet formation environment, the protoplanetary disk.

Global Simulations of the Inner Regions of Protoplanetary Disks with Comprehensive Disk Microphysics [PDF]

, 2017
The gas dynamics of weakly ionized protoplanetary disks (PPDs) are largely governed by the coupling between gas and magnetic fields, described by three non-ideal magnetohydrodynamical (MHD) effects (Ohmic, Hall, ambipolar).

An overview of the petrography and petrology of particles from aggregate sample from asteroid Bennu

Meteoritics &Planetary Science, Volume 60, Issue 5, Page 979-996, May 2025.
Abstract The OSIRIS‐REx mission returned a sample of regolith from the carbonaceous asteroid Bennu in September 2023. We present preliminary in situ investigations of the petrology and petrography of selected particles ranging in size from 0.5 to 3 mm.

Intermediate mass black holes in AGN disks: I. Production & Growth

, 2012
Here we propose a mechanism for efficiently growing intermediate mass black holes (IMBH) in disks around supermassive black holes. Stellar mass objects can efficiently agglomerate when facilitated by the gas disk.

Hydration and dehydration of CM chondrites revealed by X‐ray diffraction combined with textural observations and compositional data

Meteoritics &Planetary Science, Volume 60, Issue 5, Page 1194-1215, May 2025.
Abstract The in‐plane rotation method is used to obtain X‐ray random diffraction (XRD) patterns of polished thin sections of 10 CM chondrites. The samples include five intermediately altered CM chondrites with subtypes 2.6–2.3, two heavily altered CM chondrites with subtype 2.0 and three with secondary heating after hydration (Y 980036, Y 980051, and ...
