Interstellar extinction at high Galactic latitudes across the whole dust layer in the Galaxy

open access: bronzeASTRONOMY AT THE EPOCH OF MULTIMESSENGER STUDIES. Proceedings of the VAK-2021 conference, Aug 23–28, 2021, 2022
By use of various methods we estimate interstellar extinction at high Galactic latitudes across the whole dust layer inthe Galaxy in a variety of photometric filters. First, we compare reddening estimates from the 3D map of Green-2019(i) inside and (ii) around 23 Galactic globular clusters, i.e.

Stratified dust grains in the interstellar medium - II. Time-dependent interstellar extinction [PDF]

open access: bronzeMonthly Notices of the Royal Astronomical Society, 2010
We consider a model of diffuse cloud dust in which carbon is deposited slowly on the surfaces of silicate cores. The solid carbon is also processed by the interstellar radiation so that its optical properties change with time. The computed interstellar extinction curves (ISECs) for this model evolve in time, lie close to the observed mean ISEC for ...

The Astrodust+PAH Model: A Unified Description of the Extinction, Emission, and Polarization from Dust in the Diffuse Interstellar Medium [PDF]

open access: goldAstrophysical Journal, 2023
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

Parameterizing the interstellar dust temperature [PDF]

open access: yes, 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.

The Dust Extinction Curve: Beyond R(V)

open access: yesThe Astrophysical Journal
The dust extinction curve is typically parameterized by a single variable, R ( V ), in optical and near-infrared wavelengths. R ( V ) controls the slope of the extinction-versus-wavelength curve, and is thought to reflect the grain-size distribution and ...
