We have assembled a homogeneous database of 417 ultraviolet (UV) extinction curves for reddened sight lines having International Ultraviolet Explorer spectra. We have combined these with optical and Two Micron All Sky Survey photometry, allowing estimates of the ratio of total-to-selective extinction, RV, for the entire sample. Fitzpatrick-Massa (FM) parameters have also been found for the entire sample. This is the largest study of parameterized UV extinction curves yet published, and it… 
New Ultraviolet Extinction Curves for Interstellar Dust in M31
New low-resolution UV spectra of a sample of reddened OB stars in M31 were obtained with HST/STIS to study the wavelength dependence of interstellar extinction and the nature of the underlying dust
FUSE Measurements of Far-Ultraviolet Extinction. I. Galactic Sight Lines
We present extinction curves that include data down to far-ultraviolet wavelengths (FUV; 1050-1200 ?) for nine Galactic sight lines. The FUV extinction was measured using data from the Far
Relations between Mid-infrared Dust Emission and UV Extinction
We analyze low-resolution Spitzer infrared (IR) 5−14 μm spectra of the diffuse emission toward a carefully selected sample of stars. The sample is composed of sight lines toward stars that have
Dust properties along anomalous extinction sightlines
The large majority of extinction curves in our own Galaxy obey to a simple relation depending on one parameter, the total-to-selective extinction coefficient, R v . Different values of R v are able
The extinction law inside the 30 Doradus nebula
We have studied the interstellar extinction in a field of ~3' x 3' at the core of the 30 Doradus nebula, including the central R136 cluster, in the Large Magellanic Cloud. Observations at optical and
Milky Way Mid-Infrared Spitzer Spectroscopic Extinction Curves: Continuum and Silicate Features
We measured the mid-infrared (MIR) extinction using Spitzer photometry and spectroscopy (3.6–37 μm) for a sample of Milky Way sight lines (mostly) having measured ultraviolet extinction curves. We
Average extinction curves and relative abundances for quasi-stellar object absorption-line systems at 1 ≤zabs < 2
We have studied a sample of 809 Mg II absorption systems with 1.0 ≤ z abs ≤ 1.86 in the spectra of Sloan Digital Sky Survey quasi-stellar objects (QSOs), with the aim of understanding the nature and
The Far Ultraviolet Spectroscopic Explorer Survey of O VI Absorption in the Disk of the Milky Way
To probe the distribution and physical characteristics of interstellar gas at temperatures -->T ? 3 ? 105 K in the disk of the Milky Way, we have used the Far Ultraviolet Spectroscopic Explorer
An Analysis of the Shapes of Interstellar Extinction Curves. VII. Milky Way Spectrophotometric Optical-through-ultraviolet Extinction and Its R-dependence
We produce a set of 72 NIR through UV extinction curves by combining new HST/STIS optical spectrophotometry with existing IUE spectrophotometry (yielding gapless coverage from 1150 to 10000
An analysis of the shapes of interstellar extinction curves. V. The IR-through-UV curve morphology
We study the IR-through-UV wavelength dependence of 328 Galactic interstellar extinction curves affecting normal, near-main-sequence B and late O stars. We derive the curves using a new technique


Classification and properties of UV extinction curves
The catalog of Savage et al. ([CITE]) reporting colour excesses of 1415 stars from ANS photometry offers the opportunity to deeply investigate the characteristics of UV extinction curves which differ
Ultraviolet Extinction by Interstellar Dust in External Galaxies: M31
Hubble Space Telescope (HST) Faint Object Spectrograph (FOS) spectra of stars in OB associations of M31 are used to derive the UV extinction by interstellar dust in M31 by three different methods:
An analysis of the shapes of ultraviolet extinction curves. II - The far-UV extinction
In this paper the properties of interstellar extinction in the far-ultraviolet region are examined utilizing IUE extinction curves for a primary data sample of 45 reddened Milky Way OB stars. These
