Interstellar Extinction from Large Surveys

open access: yesOpen 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.

Ultraviolet Interstellar Extinction toward High Galactic Latitudes

open access: yesThe Astrophysical Journal
Nearby high Galactic latitude clouds provide a unique laboratory to study the physics and structure of the Galactic interstellar medium and the properties of the interstellar dust.

Interstellar extinction by composite grains [PDF]

open access: yesAstronomy & Astrophysics, 2001
Recent studies indicate that interstellar grains are composites of very small individual particles of silicates and carbon glued together into an aggregate. Using the discrete dipole approximation (DDA), we calculate the extinction, scattering and absorption eciencies for composite grains assumed to be made of a host silicate sphere with embedded ...

Interstellar extinction and polarization with homogeneous and composite grains

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011
We discuss possible ways to solve problems arising due to non-unique interpretation of interstellar extinction and linear polarization.

Interstellar Extinction in the Gaia Photometric Systems

open access: yesOpen Astronomy, 2003
Three medium-band photometric systems proposed for the Gaia space mission are intercompared in determining color excesses for stars of spectral classes from O to M at V = 18 mag.

The Gaia -ESO Survey: Tracing interstellar extinction [PDF]

open access: yes, 2015
Context. Large spectroscopic surveys have in recent years enabled computing three-dimensional interstellar extinction maps thanks to the accurate stellar atmospheric parameters and line-of-sight distances these surveys provide.

Modeling the infrared interstellar extinction [PDF]

open access: yesPlanetary and Space Science, 2014
How dust scatters and absorbs starlight in the interstellar medium (ISM) contains important clues about the size and composition of interstellar dust. While the ultraviolet (UV) and visible interstellar extinction is well studied and can be closely fitted in terms of various dust mixtures (e.g., the silicategraphite mixture), the infrared (IR ...
