Estimation of Dust Mass from Infrared Emission and Extinction of Supernova Remnants: G93.7−0.2, G109.1−1.0, G156.2+5.7, and G166.0+4.3

The Astrophysical Journal
Supernova remnants (SNRs) are major sites for both the production and destruction of interstellar dust, and quantifying their dust budget is essential for understanding the life cycle of cosmic dust.

THEMIS 2.0: A self-consistent model for dust extinction, emission, and polarisation [PDF]

Astronomy & Astrophysics
Recent observational constraints in emission, extinction, and polarisation have at least partially invalidated most of the astronomical standard grain models for the diffuse interstellar medium.

An Empirical Extinction Curve Revealed by Gaia XP Spectra and LAMOST

The Astrophysical Journal
We present a direct measurement of extinction curves using corrected Gaia XP spectra of the common sources in Gaia DR3 and LAMOST DR7. Our analysis of approximately 370,000 high-quality samples yielded a high-precision average extinction curve for the ...

Modelling interstellar extinction in three dimensions

, 2004
We have developed a technique that estimates the threedimensional extinction in the Galactic plane. The colour distribution (J-K) of stars from the Two Micron All Sky Survey (2MASS) are compared to that of stars from the Besançon model of the Galaxy, to ...

Estimation of Host Galaxy Extinction for SNe Ia

Galaxies
Type Ia supernovae are used as fundamental probes of the cosmological parameters, based on a tight empirical relation between their peak luminosity and the width of their light curve. However, it has been recognized that SNe Ia are not “standard” candles,

The interstellar extinction to V4334 Sgr (Sakurai's object)

, 2002
We present an 8–13$~\mu$m spectrum of V4334 Sgr (Sakurai's object), which shows clear evidence for the presence of a silicate absorption feature at 9.7$~\mu$m.

Variations of the Ratio of Total-To-selective Extinction in the Galaxy

Open Astronomy, 2003
The results of the study of variations of total-to-selective extinction RV near the Galactic plane (-12° ≤ b ≤+12°) are presented. It is shown that variations of RV range from 1.9 to 3.4 and it is not possible to determine its typical value for the ...

Narrow absorption lines from intervening material in supernovae

Astronomy & Astrophysics
Narrow interstellar absorption features in supernova (SN) spectra serve as valuable diagnostics for probing dust extinction and the presence of circumstellar or interstellar material.
