Fitting procedure for estimating interstellar extinction at high galactic latitudes
Open Astronomy, 2021 We determine the interstellar extinction in the selected high-latitude areas of the sky based on Gaia EDR3 astrometry and photometry and spectroscopic data from RAVE survey.

Interstellar extinction and interstellar polarization: Old and new models [PDF]
Journal of Quantitative Spectroscopy and Radiative Transfer, 2012 The review contains an analysis of the observed and model curves of the interstellar extinction and polarization. The observations mainly give information on dust in diffuse and translucent interstellar clouds. The features of various dust grain models including spherical/non-spherical, homogeneous/inhomogeneous particles are discussed.

LAMOST Spectroscopy and Gaia Photo-Astrometry for an Interstellar Extinction Study
GalaxiesThe aim of this work is to establish the present accuracy and convergence of available estimates of galactic extinction. We determine the galactic interstellar extinction in selected high-latitude areas of the sky based on Gaia DR3 astrometry and ...

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.

Modeling the infrared interstellar extinction [PDF]
Planetary and Space Science, 2014 How dust scatters and absorbs starlight in the interstellar medium (ISM) contains important clues about the size and composition of interstellar dust. While the ultraviolet (UV) and visible interstellar extinction is well studied and can be closely fitted in terms of various dust mixtures (e.g., the silicategraphite mixture), the infrared (IR ...

The Astrophysical Journal, 2023 Interstellar-dust extinction law is essential for interpreting observations. In this work, we investigate the ultraviolet (UV)–mid-infrared (IR) extinction law of the Taurus molecular cloud and its possible variations. We select 504,988 dwarf stars (4200

Dust Plasma Analogue for Interstellar 217.5 nm Extinction [PDF]
Serbian Astronomical Journal, 2008 The new ultraviolet (UV) extinction measurements of carbonaceous nanoparticles in the range from 140 nm to 260 nm are presented. The plasma polymerized hydrocarbon nanoparticles were already proposed as a new astro analogue, which describe the infrared (

The Astrophysical Journal, 2023 Dust extinction is one of the fundamental measurements of dust grain sizes, compositions, and shapes. Most of the wavelength-dependent variations seen in Milky Way extinction are strongly correlated with the single parameter R ( V ) = A ( V )/ E ( B − V )
