Silicon nanoparticles and interstellar extinction [PDF]
The Astrophysical Journal, 1998 To examine a recently proposed hypothesis that silicon nanoparticles are the source of extended red emission (ERE) in the interstellar medium, we performed a detailed modeling of the mean Galactic extinction in the presence of silicon nanoparticles.

Time-series surveys and pulsating stars: The near-infrared perspective
EPJ Web of Conferences, 2017 The purpose of this review is to discuss the advantages and problems of nearinfrared surveys in observing pulsating stars in the Milky Way. One of the advantages of near-infrared surveys, when compared to optical counterparts, is that the interstellar ...

Interstellar Extinction from Large Surveys
Open Astronomy, 2003 Under some assumptions, information on interstellar extinction may be obtained from modern large photometric survey data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from various surveys.

Diamonds and the Interstellar Extinction Curve [PDF]
Nature, 1970 IT has been suggested1 that the interstellar extinction might be explained by assuming that the interstellar dust is composed of an appropriate size distribution of diamond particles. The imaginary part of the index of refraction of diamond increases sharply from near zero to about 1.0 at λ−1 = 5.0 µm−1, giving an albedo near unity in the visible and ...

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.

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.

Evolving interstellar extinction [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 Interstellar dust containing carbon will necessarily have optical constants that respond to the local environment of the dust. This response may be sufficiently slow that the extinction produced by such dust may change on time-scales that are comparable to the likely cloud age.

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 )
