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.

SpeX Near-infrared Spectroscopic Extinction Curves in the Milky Way

The Astrophysical Journal, 2022
Interstellar dust extinction curves provide valuable information about dust properties, including the composition and size of the dust grains, and are essential to correct observations for the effects of interstellar dust.

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Modeling galactic extinction

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011
We present a model for interstellar extinction dust, in which we assume a bimodal distribution of extinction carriers, a dispersion of core-mantle grains, supplemented by a collection of PAHs in free molecular form.

More than 30 000 volunteers involved in identification of tiny rare interstellar dust particle candidates collected by the Stardust mission

Heidelberger Jahrbücher Online, 2017
The NASA Stardust mission returned the first tiny samples of interstellar dust from beyond the borders of our solar system. This region is almost devoid of matter and the interstellar dust particles floating through our solar system are extremely rare ...

Modeling of Interstellar Dust Grains

, 2008
Dust has two major effects on light passing through the Interstellar Medium - Interstellar Extinction and Reddening. Interstellar dust grains are typically a fraction of a micron, approximately the wavelength of blue light and hence light passing ...

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 ...

The Role of Benzonitrile Chlorination Explored by Dissociative Electron Attachment

ChemPhysChem, Volume 27, Issue 9, 14 May 2026.
Experimental and theoretical dissociative electron attachment study of 2‐ and 4‐chlorobenzonitrile. The dissociative electron attachment process to ortho‐ and para‐chlorobenzonitrile was investigated in the 0–12 eV energy range with a crossed‐beam time‐of‐flight mass spectrometer, supported by quantum chemical scattering calculations.
