Interstellar extinction from photometric surveys: application to four high-latitude areas [PDF]
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

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.

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 ...

Interstellar Extinction and Elemental Abundances: Individual Sight Lines [PDF]
Astrophysical Journal Supplement Series, 2021 While it is well recognized that both the Galactic interstellar extinction curves and the gas-phase abundances of dust-forming elements exhibit considerable variations from one sight line to another, as yet most of the dust extinction modeling efforts ...

The Astrodust+PAH Model: A Unified Description of the Extinction, Emission, and Polarization from Dust in the Diffuse Interstellar Medium [PDF]
Astrophysical Journal, 2022 We present a new model of interstellar dust in which large grains are a single composite material, “astrodust,” and nanoparticle-sized grains come in distinct varieties including polycyclic aromatic hydrocarbons (PAHs). We argue that a single-composition

Measuring Optical Extinction toward Young Stellar Objects Using Diffuse Interstellar Bands [PDF]
Astrophysical Journal, 2022 Line-of-sight extinction estimates of well-studied young T Tauri and Herbig Ae/Be stars are based on many different measurements and analysis methods. This has resulted in wide scatter among the published A V values for the same star.

Detection of PAH Absorption and Determination of the Mid-infrared Diffuse Interstellar Extinction Curve from the Sight Line toward Cyg OB2-12 [PDF]
Astrophysical Journal, 2020 The sight line toward the luminous blue hypergiant Cyg OB2-12 is widely used to study interstellar dust on account of its large extinction (AV ≃ 10 mag) and the fact that this extinction appears to be dominated by dust typical of the diffuse interstellar

An Analysis of the Shapes of Interstellar Extinction Curves. VIII. The Optical Extinction Structure [PDF]
Astrophysical Journal, 2020 New Hubble Space Telescope/STIS optical spectra were obtained for a sample of early-type stars with existing International Ultraviolet Explorer UV spectra. These data were used to construct optical extinction curves whose general properties are discussed

Interstellar Extinction and Elemental Abundances [PDF]
Astrophysical Journal Supplement Series, 2020 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.
