Wind line variability and intrinsic errors in observational mass loss rates
Derck Massa, Raman K. Prinja, Lidia Oskinova
UV wind line variability in OB stars appears to be universal. To quantify this variation and to estimate its effect on a mass loss rate determined from a single observation, we use…
One Relation for All Wavelengths: The Far-Ultraviolet to Mid-Infrared Milky Way Spectroscopic R(V) Dependent Dust Extinction Relationship
Karl D. Gordon, Geoffrey C. Clayton, Marjorie Decleir +4
Dust extinction is one of the fundamental measurements of dust grain sizes, compositions, and shapes. Most of the wavelength dependent variations seen in Milky Way extinction are s…
Caught in the Act: A Metal-Rich High-Velocity Cloud in the Inner Galaxy
Frances H. Cashman, Andrew J. Fox, Bart P. Wakker +8
We characterize the chemical and physical conditions in an outflowing high-velocity cloud in the inner Galaxy. We report a super-solar metallicity of [O/H] = for the…
Wind line variability and intrinsic errors in observational mass loss rates
Derck Massa, Raman K. Prinja
UV wind line variability in OB stars appears to be universal. We review the evidence that the variability is due to large, dense, optically thick structures rooted in or near the p…
Relations between mid-IR dust emission and UV extinction
Derck Massa, Karl D. Gordon, E. L. Fitzpatrick
We analyze low resolution Spitzer infrared (IR) 5-14 micron spectra of the diffuse emission toward a carefully selected sample of stars. The sample is composed of sight lines towar…
An Analysis of the Shapes of Interstellar Extinction Curves. VIII. The Optical Extinction Structure
D. Massa, E. L. Fitzpatrick, K. D. Gordon
New HST/STIS optical spectra were obtained for a sample of early type stars with existing IUE UV spectra. These data were used to construct optical extinction curves whose general…
