Accumulation of Dust on a Surface and the Subsequent Formation of Compact Aggregate Piles

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Dust aggregation is a prominent topic in space physics, yet the accumulation of dust on surfaces in airless environments remains poorly understood. It is commonly assumed that, during the initial stages of dust deposition, particles spread uniformly to form a monolayer.

Disk2Planet: A Robust and Automated Machine Learning Tool for Parameter Inference in Disk–Planet Systems

The Astrophysical Journal
We introduce Disk2Planet, a machine-learning-based tool to infer key parameters in disk–planet systems from observed protoplanetary disk structures. Disk2Planet takes as input the disk structures in the form of 2D density and velocity maps, and outputs ...

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 statistical investigation into relationships between the IIE irons and the ordinary, F and “HH” chondrites

Meteoritics &Planetary Science, Volume 60, Issue 10, Page 2376-2400, October 2025.
Abstract It has been proposed that IIE iron meteorites formed through impact processes on a parent body that was composed of either the H chondrites or a much‐debated fourth ordinary chondrite group, the HH chondrites. To resolve this debate, we have compiled a large dataset for the ordinary chondrites, low‐fayalite ungrouped chondrites, and IIE irons,

Shadows, gaps, and ring-like structures in protoplanetary disks [PDF]

, 2011
We study the structure of passively heated disks around T Tauri and Herbig Ae stars, and present a vectorized Monte Carlo dust radiative transfer model of protoplanetary disks. The vectorization provides a speed up factor of 100 when compared to a scalar

Sites of Planet Formation in Binary Systems. I. Evidence for Disk−Orbit Alignment in the Close Binary FO Tau

The Astronomical Journal
Close binary systems present challenges to planet formation. As binary separations decrease, so do the occurrence rates of protoplanetary disks in young systems and planets in mature systems.

Disk formation and structure*

EPJ Web of Conferences, 2015
In this chapter, we cover the formation of protoplanetary disk as a natural byproduct of the gravitational collapse of a slowly rotating, hydrostatic cloud.

The Structure and Evolution of Protoplanetary Disks: an infrared and submillimeter view

, 2015
Circumstellar disks are the sites of planet formation, and the very high incidence of extrasolar planets implies that most of them actually form planetary systems.
