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.

Interstellar extinction from photometric surveys: application to four high-latitude areas [PDF]

Open Astronomy, 2018
Information on interstellar extinction and dust properties may be obtained from modern large photometric surveys data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from various surveys. It yields a

Interstellar extinction and polarization with homogeneous and composite grains

Atti 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 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 computation of interstellar extinction in photoionized nebulae

Astronomy & Astrophysics, 2023
Context. The proper plasma analysis practice (PPAP) method has been proposed to analyze spectroscopic data of ionized nebulae. The method is based on a coherent and simultaneous determination of the reddening correction and physical conditions in nebulae.

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

, 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.

New Candidate Massive Clusters from 2MASS [PDF]

, 2013
Massive stars are important for the evolution of the interstellar medium. The detailed study of their properties (such as mass loss, rotation, magnetic fields) is enormously facilitated by samples of these objects in young massive galactic star clusters.

High spatial resolution galactic 3D extinction mapping with IPHAS [PDF]

, 2008
We present an algorithm (MEAD, for 'Mapping Extinction Against Distance') which will determine intrinsic (r' - i') colour, extinction, and distance for early-A to K4 stars extracted from the IPHAS r'/ i'/H alpha photometric data base.
