Interstellar Reddening Towards S188, Hw4 and We1–6 [PDF]

open access: bronzeSymposium - International Astronomical Union, 1993
Photoelectric UBV photometry of stars was carried out in the angular vicinity (radius = 15′) of 3 planetary nebulae. An extinction distance relation was constructed for the line of sight towards each planetary nebula. This relation was verified by published data on nearby stars and star clusters. The distances derived are 850 ± 300 pc for PK 128 −04 1 (

The Interstellar Reddening and Metallicity of NGC 330 [PDF]

open access: bronzeSymposium - International Astronomical Union, 1991
A reddening of E(B-V) = 0.12 ± 0.02 has been determined for NGC 330 in the Small Magellanic Cloud (SMC) from spectrophotometry of B stars in the cluster. This high reddening helps explain many of the anomalous low metallicity estimates for the cluster. Preliminary analysis of Coudé spectra of K giants in the cluster indicates a high value of 3.5 to 4.5

Distribution of Interstellar Reddening Material in the Galactic Plane [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1987
By using the recently determined color excess and distance data of classical cepheids by Kim(1985), the distribution of interstellar reddening material was studied to see the general picture of the average rate of interstellar absorption out to about 7 ...

Novel Correlations between Diffuse Interstellar Bands and Optical Reddening

open access: hybridResearch Notes of the AAS, 2022
Abstract The relatively new and expansive Apache Point Observatory Catalog of Optical Diffuse Interstellar Bands was analyzed to identify novel correlations between diffuse interstellar bands (DIBs) and optical reddening E(B − V), with a principal aim being to facilitate future identifications of the host molecular carriers.

Studies of interstellar reddening

open access: green, 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 band at 4430A. The existing measures, obtained principally from low dispersion objective prism spectra,

Diffuse interstellar bands in the near-infrared: expanding the reddening range [PDF]

open access: goldMonthly Notices of the Royal Astronomical Society
ABSTRACT We have investigated the behaviour of three strong near-infrared diffuse interstellar bands (DIBs) at λ13177 Å, λ14680 Å, and λ15272 Å, on a larger sample of sightlines and over a wider range of extinctions than previously studied, utilizing spectra from three observatories.
