Internal and External Alignment of Carbonaceous Grains within the Radiative Torque Paradigm
The Astrophysical Journal, 2023 We study the internal and external alignment of carbonaceous grains in the interstellar medium (ISM) within the Radiative Torque (RAT) paradigm.

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.

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 Astrophysical Journal, 2023 Direct photometric measurements of the cosmic optical background (COB) provide an important point of comparison to both other measurement methodologies and models of cosmic structure formation, and permit a cosmic consistency test with the potential to ...

Frontiers in Astronomy and Space Sciences, 2022 Modern understanding of dust astrophysics reveals that radiative torques (RATs) arising from the radiation–dust interaction can induce two fundamental effects: grain alignment and rotational disruption.

Gap-opening Planets Make Dust Rings Wider
The Astrophysical Journal, 2023 As one of the most commonly observed disk substructures, dust rings from high-resolution disk surveys appear to have different radial widths. Recent observations on PDS 70 and AB Aur reveal not only planets in the disk, but also the accompanying wide ...
