Dust absorption and scattering in the silicon K-edge [PDF]
, 2019 The composition and properties of interstellar silicate dust are not well understood. In X-rays, interstellar dust can be studied in detail by making use of the fine structure features in the Si K-edge.

An R V Map of the Milky Way Revealed by LAMOST
The Astrophysical Journal Supplement Series, 2023 The total-to-selective extinction ratio, R _V , is a key parameter for tracing the properties of interstellar dust, as it directly determines the variation of the extinction curve with wavelength.

Correcting for the Effects of Interstellar Extinction [PDF]
, 1998 This paper addresses the issue of how best to correct astronomical data for the wavelength-dependent effects of Galactic interstellar extinction. The main general features of extinction from the IR through the UV are reviewed, along with the nature of ...

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.

Hubble Tarantula Treasury Project. IV. The extinction law [PDF]
, 2015 We report on the study of interstellar extinction across the Tarantula nebula (30 Doradus), in the Large Magellanic Cloud, using observations from the Hubble Tarantula Treasury Project in the 0.3 - 1.6 micron range. The considerable and patchy extinction

Distortion of Magnetic Fields in a Starless Core III: Polarization--Extinction Relationship in FeSt 1-457 [PDF]
, 2018 The relationship between dust polarization and extinction was determined for the cold dense starless molecular cloud core FeSt 1-457 based on the background star polarimetry of dichroic extinction at near-infrared wavelengths.

Interstellar extinction from photometric surveys: application to four high-latitude areas
Open Astronomy, 2018 Information on interstellar extinction and dust properties may be obtained from modern large photometric surveys data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from various surveys. It yields a

The Mid-Infrared Extinction Law and its Variation in the Coalsack Nebula [PDF]
, 2013 In recent years the wavelength dependence of interstellar extinction from the ultraviolet (UV), optical, through the near- and mid-infrared (IR) has been studied extensively.

Interstellar Extinction and Elemental Abundances [PDF]
The Astrophysical Journal Supplement Series, 2021 Abstract Elements in the interstellar medium (ISM) exist in the form of gas or dust. The interstellar extinction and elemental abundances provide crucial constraints on the composition, size, and quantity of interstellar dust. Most of the extinction modeling efforts have assumed the total (gas and dust) abundances of the dust-forming ...
