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 ...

The Correlation of Interstellar Reddening and Lα Absorption [PDF]

open access: yesSymposium - International Astronomical Union, 1973
For 61 stars whose interstellar Lα absorption was observed by OAO-2, the average relation of H I column density to B – V color excess is equal to 5 × 1021 atoms cm–2 mag–1. For a recent dust grain model this value implies that the density ratio 〈ρHI/ρdust〉 ≈ 100.

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

open access: yesMonthly 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.

The Ultraviolet to Mid-infrared Extinction Law of the Taurus Molecular Cloud Based on the Gaia DR3, GALEX, APASS, Pan-STARRS1, 2MASS, and WISE Surveys

open access: yesThe Astrophysical Journal, 2023
Interstellar-dust extinction law is essential for interpreting observations. In this work, we investigate the ultraviolet (UV)–mid-infrared (IR) extinction law of the Taurus molecular cloud and its possible variations. We select 504,988 dwarf stars (4200

HST NIC3 Photometry of Metal-Rich Globular Clusters Palomar 6, Liller 1, and 47 Tuc (NGC 104) [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2004
We present HST NIC3 photometry of metal-rich globular clusters Palomar 6, Liller 1 and 47 Tuc (NGC 104). We discuss the interstellar reddening law for the HST NICMOS F110W/F160W photometric system which depends on the temperature of the source.
