Interstellar dust in the heliosphere [PDF]

, 1992
In the early 1990s, after its Jupiter flyby, the Ulysses spacecraft identified interstellar dust in the solar system. Since then the in-situ dust detector on board Ulysses continuously monitored interstellar grains with masses up to 10(-13) kg ...

The nature of interstellar dust as revealed by light scattering

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011
Interstellar dust was first identified through the extinction that it causes of optical starlight. Initially, observational and theoretical studies of extinction were made to identify simple ways of removing the effect of extinction.

Interstellar X-Ray Absorption and Scattering

The Astrophysical Journal
Accurate estimates of the absorption of X-rays by interstellar gas and dust are of crucial importance for the analysis and interpretation of almost all astronomical soft X-ray observations.

Recent progress in theory and observational study of dust grain alignment and rotational disruption in star-forming regions

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.

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

Chemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

The formation of molecular hydrogen in the interstellar medium [PDF]

, 2010
H2 is the most abundant molecule in the interstellar medium and forms on the surface of interstellar dust grains. Laboratory studies have been conducted of HD formation on a dust grain analogue, which is a highly-oriented pyrolytic graphite surface ...

Modelling DESTINY+ interplanetary and interstellar dust measurements en route to the active asteroid (3200) Phaethon [PDF]

, 2019
The JAXA/ISAS spacecraft DESTINY+ will be launched to the active asteroid (3200) Phaethon in 2022. Among the proposed core payload is the DESTINY+ Dust Analyzer (DDA) which is an upgrade of the Cosmic Dust Analyzer flown on the Cassini spacecraft to ...

Proximity Proteomics Maps Candidate Cellular Uptake Pathways for Cell‐Derived Nanovesicles

Small Methods, EarlyView.
TurboID‐based dual‐sided proteomics compares mechanically generated cell‐derived nanovesicles with naturally secreted small extracellular vesicles. Vesicle proteomes define candidate interaction signatures, while recipient‐cell proximity labelling identifies exposure‐associated proteins.

Dust in the Local Interstellar Wind

The Astrophysical Journal, 1999
The gas-to-dust mass ratios found for interstellar dust within the Solar System, versus values determined astronomically for the cloud around the Solar System, suggest that large and small interstellar grains have separate histories, and that large interstellar grains preferentially detected by spacecraft are not formed exclusively by mass exchange ...
