Interstellar Dust in the Solar System: Model versus In-Situ Spacecraft Data [PDF]
Astronomy & Astrophysics, 2019 In the early 1990s, contemporary interstellar dust penetrating deep into the heliosphere was identified with the in-situ dust detector on board the Ulysses spacecraft.

Lifetimes of interstellar dust from cosmic ray exposure ages of presolar silicon carbide. [PDF]
Proc Natl Acad Sci U S A, 2020 Significance Dating of interstellar dust directly with astronomical methods is not possible. Neither is dating based on the decay of long-lived radioactive nuclides, due to current analytical limitations and unknown initial isotopic compositions. Here we

Express assessment of neurotoxicity of particles of planetary and interstellar dust. [PDF]
NPJ Microgravity, 2019 Establishment of high-quality, consistent on-board assessment of the neurotoxicity of planetary, and interstellar dust particles will be required to predict their potential threat to human health during long-term space missions.

INTERSTELLAR DUST GRAINS [PDF]
Annual Review of Astronomy and Astrophysics, 2003 ▪ Abstract This review surveys the observed properties of interstellar dust grains: the wavelength-dependent extinction of starlight, including absorption features, from UV to infrared; optical luminescence; infrared emission; microwave emission; optical,

IRON: A KEY ELEMENT FOR UNDERSTANDING THE ORIGIN AND EVOLUTION OF INTERSTELLAR DUST. [PDF]
Astrophys J, 2016 The origin and depletion of iron differ from all other abundant refractory elements that make up the composition of interstellar dust. Iron is primarily synthesized in Type Ia supernovae (SNe Ia) and in core collapse supernovae (CCSN), and is present in ...

Aliphatic hydrocarbon content of interstellar dust [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 The mid-IR spectrum of the interstellar medium contains both aromatic and aliphatic hydrocarbon features. These are generally attributed to carbonaceous dust.

Parameterizing the interstellar dust temperature [PDF]
, 2017 The temperature of interstellar dust particles is of great importance to astronomers. It plays a crucial role in the thermodynamics of interstellar clouds, because of the gas-dust collisional coupling.

Iron and silicate dust growth in the Galactic interstellar medium: clues from element depletions [PDF]
, 2018 The interstellar abundances of refractory elements indicate a substantial depletion from the gas phase, that increases with gas density. Our recent model of dust evolution, based on hydrodynamic simulations of the lifecycle of giant molecular clouds ...

Dust Emission in Galaxies at Millimeter Wavelengths: Cooling of star forming regions in NGC6946 [PDF]
EPJ Web of Conferences, 2022 Interstellar dust plays an important role in the formation of molecular gas and the heating and cooling of the interstellar medium. The spatial distribution of the mm-wavelength dust emission from galaxies is largely unexplored. The NIKA2 Guaranteed Time
