, 2003 The formation of small solid particles (dust grains) from the gas phase in the circumstellar environments of evolved stars or the atmospheres of substellar objects (brown dwarfs) requires suitable physical and chemical conditions. The temperature and density of the gas have to be confined to a certain regime, the emph{dust formation window}, in order ...

Rotational Disruption of Astrophysical Dust and Ice—Theory and Applications
Galaxies, 2020 Dust is an essential component of the interstellar medium (ISM) and plays an important role in many different astrophysical processes and phenomena.

Effects of Barnett Magnetic Dipole–Dipole Interaction on Grain Growth and Destruction
The Astrophysical Journal, 2023 Rapidly spinning magnetic grains can acquire large magnetic dipole moments due to the Barnett effect. Here we study the new effect of Barnett magnetic dipole–dipole interaction on grain–grain collisions and grain growth, assuming that grains are spun up ...

Supernova Dust Evolution Probed by Deep-sea 60Fe Time History
The Astrophysical Journal, 2023 There is a wealth of data on live, undecayed ^60 Fe ( t _1/2 = 2.6 Myr) in deep-sea deposits, the lunar regolith, cosmic rays, and Antarctic snow, which is interpreted as originating from the recent explosions of at least two near-Earth supernovae.

Physical models of streaming instabilities in protoplanetary discs [PDF]
, 2020 We develop simple, physically motivated models for drag-induced dust–gas streaming instabilities, which are thought to be crucial for clumping grains to form planetesimals in protoplanetary discs.

The Astrophysical Journal, 2023 We present a new model of interstellar dust in which large grains are a single composite material, “astrodust,” and nanoparticle-sized grains come in distinct varieties including polycyclic aromatic hydrocarbons (PAHs). We argue that a single-composition

The penetration of FUV radiation into molecular clouds [PDF]
, 2006 The solution of the FUV radiative transfer equation can be complicated if the most relevant radiative processes such as dust scattering and gas line absorption are included, and have realistic (non-uniform) properties.
