Interstellar reddening in the galaxy [PDF]

, 1964
Objective prism spectra obtained with the 16/24/60-inch Schmidt telescope have been used for an investigation of the wavelength dependence of interstellar absorption in the spectral range from 8000A to 3450A, in a region of 30 square degrees in ...

The Effect of a Nonuniversal Extinction Curve on the Wesenheit Function and Cepheid Distances

The Astrophysical Journal Letters
The Wesenheit function is widely used to reduce the effects of interstellar reddening in distance measurements. Its construction, however, relies on the assumption of a universal extinction curve and on fixed values of the total-to-selective extinction ...

DETERMINING INTERSTELLAR REDDENING: A NEW APPROACH USING SPECTROSCOPY AND PHOTOMETRY [PDF]

, 2011
The mystery of Canis Major overdensity is addressed. We discuss concurrent methods and their limitations on the determination of interstellar reddening.

Three-dimensional Reddening Maps of the Magellanic Clouds Constructed by RR Lyrae Stars

The Astronomical Journal
We present the first three-dimensional reddening maps of the Large and Small Magellanic Clouds (LMC and SMC) constructed using fundamental-mode RR Lyrae stars (RRab) from the Optical Gravitational Lensing Experiment (OGLE) survey.

Mapping Interstellar Dust in the Foreground Outer Disk of Overlapping Galaxy Pair VV 191 with HST and JWST

The Astronomical Journal
VV 191 is a nearby ( z ∼ 0.05), overlapping (occulting) galaxy pair, where a multiple-armed spiral galaxy is backlit by an elliptical galaxy. The overlap is used to derive and map dust attenuation in two James Webb Space Telescope NIRCam filters (F090W ...

Overlapping Open Clusters NGC 1750 and NGC 1758 behind the Taurus Dark Clouds. II. CCD Photometry in the Vilnius System

Open Astronomy, 2003
Seven-color photometry in the Vilnius system has been obtained for 420 stars down to V = 16 mag in the area containing the overlapping open clusters NGC 1750 and NGC 1758 in Taurus.

An intrinsic source of reddening in the cataclysmic variable SS Cygni

, 2010
By using the INES archive of the IUE satellite, we analyzed the spectra of SS Cygni in quiescence in order to determine the value of the reddening of the binary system.

Estimating accurate reddening values of LAMOST M dwarfs

, 2022
M dwarfs are the dominating type of stars in the solar neighbourhood. They serve as excellent tracers for the study of the distribution and properties of the nearby interstellar dust.

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.

The Flattest Infrared Extinction Curve in Four Isolated Dense Molecular Cloud Cores

The Astrophysical Journal Letters
The extinction curve of interstellar dust in the dense molecular cloud cores is crucial for understanding dust properties, particularly size distribution and composition.
