Deciphering the Origin of the Regular Satellites of Gaseous Giants - Iapetus: the Rosetta Ice-Moon [PDF]

, 2009
Here we show that Iapetus can serve to discriminate between satellite formation models. Its accretion history can be understood in terms of a two-component gaseous subnebula, with a relatively dense inner region, and an extended tail out to the location ...

Formation of Asteroid (16) Psyche by a Giant Impact

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Asteroid (16) Psyche is the largest likely metal‐rich asteroid in the Solar System and the target of the NASA Psyche mission. The mission aims to determine whether the asteroid is the core of a differentiated planetesimal that lost its mantle via a giant impact.

Mechanical Modification of Chondrule Fine-grained Rims by Dusty Nebular Shocks

The Planetary Science Journal, 2023
The mechanical processes that convert an initially fluffy chondrule fine-grained rim (FGR) into a more compact structure remain poorly characterized.

JWST Imaging of Edge-on Protoplanetary Disks. II. Appearance of Edge-on Disks with a Tilted Inner Region: Case Study of IRAS04302+2247

The Astrophysical Journal
We present James Webb Space Telescope imaging from 2 to 21 μ m of the edge-on protoplanetary disk around the embedded young star IRAS04302+2247. The structure of the source shows two reflection nebulae separated by a dark lane.

Isolating Dust and Free–Free Emission in ONC Proplyds with ALMA Band 3 Observations

The Astrophysical Journal, 2023
The Orion Nebula Cluster (ONC) hosts protoplanetary disks experiencing external photoevaporation by the cluster’s intense UV field. These “proplyds” are comprised of a disk surrounded by an ionization front.

The Formation and Dynamics of Super-Earth Planets

, 2013
Super-Earths, objects slightly larger than Earth and slightly smaller than Uranus, have found a special place in exoplanetary science. As a new class of planetary bodies, these objects have challenged models of planet formation at both ends of the ...

Modeling enstatite chondrites: Reduced rocks with a pinch of oxidized material (affected by varying H2O(g)) derived from planetesimals shocked during the epoch of giant–planet migration

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 122-139, January 2026.
Abstract The O‐, N‐, Mo‐, Ru‐, Os‐, Cr‐, Ti‐, Ni‐, Fe‐, Nd‐, Ca‐, Zn‐, Sr‐, and Mg‐isotopic compositions of enstatite chondrites are essentially identical to those of the Earth and Moon. These correspondences suggest enstatite chondrites formed at ≈1 AU as the only known chondrite groups that accreted in the vicinity of a major planet. Bulk Earth has a

Long-term Protoplanetary Disk Evolution from Molecular Cloud Core Collapse and Implications for Planet Formation. II. Strong Disk Self-gravity

The Astrophysical Journal, 2023
We continue to investigate long-term protoplanetary disk evolution and focus on the situation of strong disk self-gravity (DSG). We call such a disk a type III disk. A large amount of mass is stored in the disk due to large angular momentum.

The Qingzhen reaction, a fine‐grained mineral assemblage associated with djerfisherite in some EH3 chondrites: Alteration on the EH parent body

Meteoritics &Planetary Science, Volume 60, Issue 12, Page 2913-2934, December 2025.
Abstract Enstatite chondrites formed under extremely reducing conditions in the protoplanetary disk. They are derived from two or more parent bodies, EH and EL, and both EH and EL groups contain petrologic type 3–6 samples. The rare lithophile‐ and halogen‐bearing sulfide, djerfisherite, occurs in low abundance in enstatite chondrites, most frequently ...
