Preliminary results on interstellar reddening as deduced from filter photometry
, 1972 Filter photometry has been used to derive the interstellar reddening law from stars through the study of a single spectral type, B0. The deficiency in the far ultraviolet flux of a supergiant relative to a main sequence star is compared with the ...

Studies of interstellar reddening [PDF]
, 1969 The wavelength dependence of interstellar obscuration, in magnitudes against reciprocal wavelength, is known to be well represented, over the visible part of the spectrum, by two straight lines intersecting at or near the broad interstellar absorption

The Astronomical JournalThe viability of the star count (Wolf) method is assessed as a means of constraining the near-infrared (NIR) extinction law toward the Corona Australis molecular cloud. Using deep JHK _S photometry from the VISIONS survey, extinction maps with 1′ spatial

DIFFUSE INTERSTELLAR BAND 6202 ˚ A AS AN INDICATOR OF ORGANIC MATTER IN COSMOS: CEPHEID SPECTRA
Odessa Astronomical Publications, 2019 We have described the method of investigation of the diffuse interstellar band (DIB) at 6202 ˚ A. This DIB is seen in the spectra of cepheid stars, and it is blended with two stellar lines of Ce II (6201.773 ˚ A) and Ni I (6204.6 ˚ A).

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.

Benchmarking Differential Reddening in Front of Globular Clusters
The Astronomical JournalInterstellar extinction is a major obstacle in determining accurate stellar parameters from photometry near the Galactic disk. It is especially true for globular clusters at low galactic latitudes, which suffer from significant amounts of spatially ...

Open Astronomy, 2010 The contamination in the Gaia BP and RP spectra, caused by the LSF smearing, is a serious obstacle for the classification of stars since the contamination values at different wavelengths depend on temperatures, gravities, metallicities and interstellar ...

Searching for a variability of interstellar reddening in the line of sight of NGC 4833
, 2015 International audienceThe globular cluster NGC 4833 lies near the galactic plane. It is known to exhibit a strong differential reddening caused by several galactic interstellar clouds in its line of sight.

A Study of Interstellar Reddening at High Galactic Latitudes [PDF]
Symposium - International Astronomical Union, 1973 A series of finding lists of A stars in regions at high galactic latitudes has been published in the last few years. Strömgren four-color and Hβ measures have been made of stars in five of the regions, allowing the interstellar absorption in each to be calculated.
