Probing the Distinct Extinction Law of the Pillars of Creation in M16 with JWST
The Astrophysical Journal LettersInvestigating the extinction law in regions of high dust extinction, such as the Pillars of Creation within the M16 region, is crucial for understanding the densest parts of the interstellar medium (ISM).

The Astronomical JournalThe viability of the star count (Wolf) method is assessed as a means of constraining the near-infrared (NIR) extinction law toward the Corona Australis molecular cloud. Using deep JHK _S photometry from the VISIONS survey, extinction maps with 1′ spatial

Open Astronomy, 2011 A medium-band 12-color photometric system, based on the decontaminated Gaia BP/RP spectra, has been proposed in our Paper II. Here we analyze a possibility to apply some versions of this system for the determination of temperatures and gravities of stars

Interstellar reddening using the VO and determination of PNe distances
, 2009 We discuss the application of Virtual Observatory (VO) tools for the determination of interstellar reddening by the use of photometric data and spectral type information of stars near a selected line of sight. We illustrate this technique with an example

DIFFUSE INTERSTELLAR BAND 6202 ˚ A AS AN INDICATOR OF ORGANIC MATTER IN COSMOS: CEPHEID SPECTRA
Odessa Astronomical Publications, 2019 We have described the method of investigation of the diffuse interstellar band (DIB) at 6202 ˚ A. This DIB is seen in the spectra of cepheid stars, and it is blended with two stellar lines of Ce II (6201.773 ˚ A) and Ni I (6204.6 ˚ A).

Modeling of Interstellar Dust Grains
, 2008 Dust has two major effects on light passing through the Interstellar Medium - Interstellar Extinction and Reddening. Interstellar dust grains are typically a fraction of a micron, approximately the wavelength of blue light and hence light passing ...

Benchmarking Differential Reddening in Front of Globular Clusters
The Astronomical JournalInterstellar extinction is a major obstacle in determining accurate stellar parameters from photometry near the Galactic disk. It is especially true for globular clusters at low galactic latitudes, which suffer from significant amounts of spatially ...

Open Astronomy, 2010 The contamination in the Gaia BP and RP spectra, caused by the LSF smearing, is a serious obstacle for the classification of stars since the contamination values at different wavelengths depend on temperatures, gravities, metallicities and interstellar ...

On the Relation between Interstellar Spectral Features and Reddening
Acta Astronomica, 2019 It is well known that interstellar spectral features correlate with color excess E(B$-$V). This suggests that measuring intensities of these features allows one to estimate reddening of stars. The aim of this paper is to check how tight intensities of interstellar diffuse bands (DIBs)are related to the amount of extinction, measured using E(B$-$V).
