Gas mass tracers in protoplanetary disks: CO is still the best [PDF]
, 2017 Protoplanetary disk mass is a key parameter controlling the process of planetary system formation. CO molecular emission is often used as a tracer of gas mass in the disk.

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 464-483, March 2025.Abstract Xenoliths in carbonaceous chondrites include lithologies that are unrepresented in the meteorite record and so are a rich source of information on asteroid diversity. Cold Bokkeveld is a CM2 regolith breccia that contains both hydrous and anhydrous lithic clasts. Here, we describe a hydrous clast with a fine‐grained rim.

The Evolution of Protoplanetary Disk Edges [PDF]
The Astrophysical Journal, 2004 We investigate gap formation in gaseous protostellar disks by a planet in a circular orbit in the limit of low disk viscosity. This regime may be appropriate to an aging disk after the epoch of planet formation. We find that the distance of planet to the gap outer boundary can be between the location of the $m=2$ and $m=1$ outer Lindblad resonances ...

Modeling and interpretation of images*
EPJ Web of Conferences, 2015 Imaging protoplanetary disks is a challenging but rewarding task. It is challenging because of the glare of the central star outshining the weak signal from the disk at shorter wavelengths and because of the limited spatial resolution at longer ...

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 544-569, March 2025.Abstract Refractory inclusions (RIs) in chondrites are widely used as tracers of early solar system formation conditions. In the context of sample‐return missions, a non‐destructive and non‐invasive analytical tool that can rapidly detect and characterize RIs in space samples during their early phase of study is highly needed.

Light Echoes of Protoplanetary Disks
The Astrophysical JournalLight echoes offer a means of studying protoplanetary disks, including their geometry and composition, even when they are not spatially resolved. We present a test of this approach applied specifically to optically thick, geometrically flared disks ...

Zooming in on the Formation of Protoplanetary Disks [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractWe use the adaptive mesh refinement code RAMSES to model the formation of protoplanetary disks in realistic star formation environments. The resolution scales over up to 29 powers of two (~ 9 orders of magnitude) covering a range from outer scales of 40 pc to inner scales of 0.015 AU. The accretion rate from a 1.5 solar mass envelope peaks near

Accretion of Solid Materials onto Circumplanetary Disks from Protoplanetary Disks [PDF]
, 2014 We investigate accretion of solid materials onto circumplanetary disks from heliocentric orbits rotating in protoplanetary disks, which is a key process for the formation of regular satellite systems.
