An Analysis of the Shapes of Ultraviolet Extinction Curves. III. an Atlas of Ultraviolet Extinction Curves

open access: yesAstrophysical Journal, Supplement Series, 1990
The basic data needed to produce UV extinction curves for a sample of 78 stars, including spectral types, visual photometry, parameters used to produce fits to the UV extinction curves, distances to the program stars, and line-of-sight H I column densities, are presented.

Far-ultraviolet extinction in σ Scorpii

Astrophysics and Space Science, 1975
It was found earlier from OAO-2 data (Bless and Savage, 1972) that considerable variability with direction in space is present in both the shape and level (relative to B-V color excess) of the interstellar extinction curve in the far ultraviolet. The star σ Sco was shown to be a case of extremely low UV extinction, but there was some question of ...

Empirical extinction coefficients for the Swift-UVOT optical-through-ultraviolet passbands

open access: yesMonthly Notices of the Royal Astronomical Society, 2023
We calculated empirical reddening and extinction coefficients with respect to the dust reddening map of Schlegel et al. for the Swift-UVOT passbands, using the 'star pair' method and photometric data from the UVOT Serendipitous Source Catalogue and ...
