Unified model for interstellar extinction and polarization [PDF]
, 1967 The development of improved techniques for measuring interstellar extinction and polarization has led to a revival of interest in the investigation of grain models.

Interstellar extinction toward the Galactic bulge [PDF]
, 2019 The past decade has seen rapid progress in studies on the Galactic bulge thanks to many large-scale surveys in both photometric and spectroscopic approaches.

Interstellar extinction by quartz grains [PDF]
, 1968 Knacke has pointed out that quartz particles possess strong absorption bands at λ ~ 10μ. Although these features occur in the spectral region 3-10μ, where Johnson has found humps in interstellar extinction curves, by itself

DIBs, interstellar dust, and extinction [PDF]
, 2014 The relationship between DIBs and dust is still unknown. The correlation between reddening and DIB strength means that the DIBs are mixed in with the dust and gas in interstellar clouds. The DIBs are relatively stronger in the diffuse interstellar medium

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.

Measurements of Interstellar Extinction [PDF]
Symposium - International Astronomical Union, 1989 The results of interstellar extinction measurements from the near IR to the far-UV are reviewed. The average interstellar extinction curve for the diffuse cloud medium exhibits a nearly linear rise (in 1/λ) from 1 μm−1 to the 2.25 μm−1 “knee” in extinction where the slope changes.

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 ...

Structure in the Interstellar-Extinction Curve
The Astrophysical Journal, 1971 Using photographic techniques, it was attempted to obtain spectra of the interstellar material at a resolution of about 5 A. Three classes of structures are discussed. It is pointed out that the optical observations can be extended into the UV with a resolution of 0.4 A using the OAO-C telescope.

The nature of interstellar dust as revealed by light scattering
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011 Interstellar dust was first identified through the extinction that it causes of optical starlight. Initially, observational and theoretical studies of extinction were made to identify simple ways of removing the effect of extinction.
