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.

Dust evolution, a global view: III. Core/mantle grains, organic nano-globules, comets and surface chemistry [PDF]
Royal Society Open Science, 2016 Within the framework of The Heterogeneous dust Evolution Model for Interstellar Solids (THEMIS), this work explores the surface processes and chemistry relating to core/mantle interstellar and cometary grain structures and their influence on the nature ...

Determination of the Branching Ratio of CH3OH + OH Reaction on Water Ice Surface at 10 K
The Astrophysical Journal, 2023 The CH _3 O and CH _2 OH radicals can be important precursors of complex organic molecules (COMs) in interstellar dust. The COMs presumably originating from these radicals were abundantly found in various astronomical objects.

Consequences of the Solar System passage through dense interstellar clouds [PDF]
Annales Geophysicae, 2003 Several consequences of the passage of the solar system through dense interstellar molecular clouds are discussed. These clouds, dense (more than 100 cm-3), cold (10–50 K) and extended (larger than 1 pc), are characterized by a gas-to-dust mass ...

Unusual Chemical Processes in Interstellar Chemistry: Past and Present
Frontiers in Astronomy and Space Sciences, 2021 The chemistry that occurs in interstellar clouds consists of both gas-phase processes and reactions on the surfaces of dust grains, the latter particularly on and in water-dominated ice mantles in cold clouds.
