- E. Fitzpatrick, D. Massa
- Physics
- 1990
Les donnees de base necessaires pour produire les courbes d'extinction UV sont assemblees pour un echantillon de 78 etoiles qui ont ete analysees dans les articles anterieurs de la serie. Les donnees…
AN ANALYSIS OF THE SHAPES OF INTERSTELLAR EXTINCTION CURVES. VI. THE NEAR-IR EXTINCTION LAW
- E. Fitzpatrick, D. Massa
- Physics
- 1 May 2009
We combine new observations from the Hubble Space Telescope's Advanced Camera of Survey with existing data to investigate the wavelength dependence of near-IR (NIR) extinction. Previous studies…

An analysis of the shapes of ultraviolet extinction curves. II - The far-UV extinction
- E. Fitzpatrick, D. Massa
- Physics
- 1 May 1988
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…
Quantitative studies of the optical and UV spectra of Galactic early B supergiants - I. Fundamental parameters
- S. C. Searle, R. Prinja, D. Massa, R. Ryans
- Physics
- 28 January 2008
Aims. We undertake an optical and ultraviolet spectroscopic analysis of a sample of 20 Galactic B0-B5 supergiants of luminosity classes Ia, Ib, Iab, and II. Fundamental stellar parameters are…
A CATALOG OF ULTRAVIOLET INTERSTELLAR EXTINCTION EXCESSES FOR 1415 STARS
- B. Savage, D. Massa, M. Meade, P. Wesselius
- Physics
- 1 November 1985
Ultraviolet interstellar extinction excesses are presented for 1415 stars with spectral types B7 and earlier. The excesses with respect to V are derived from Astronomical Netherlands Satellite (ANS)…
Fundamental Properties and Distances of the Large Magellanic Cloud from Eclipsing Binaries. II. HV 982
- E. Fitzpatrick, I. Ribas, E. Guinan, L. E. Dewarf, F. Maloney, D. Massa
- Physics
- 2002
We have determined the distance to a second eclipsing binary (EB) system in the Large Magellanic Cloud, HV 982 (DB1 IVV ) DB1 IVV). The measurement of the distanceamong other properties of the…
Preliminary Characterization of the Post- Launch Line Spread Function of COS
- P. Ghavamian, A. Aloisi, S. Osterman
- Physics
- 1 October 2009
We present a preliminary analysis of the line spread function (LSF) of the Cosmic Origins Spectrograph (COS) using FUV and NUV stellar spectra acquired during the SM4 Servicing Mission Observatory…
Determining the Physical Properties of the B Stars. I. Methodology and First Results
- E. Fitzpatrick, D. Massa
- Physics
- 15 June 1999
We describe a new approach to fitting the UV-to-optical spectra of B stars to model atmospheres and present initial results. Using a sample of lightly reddened stars, we demonstrate that the Kurucz…
An Analysis of the Shapes of Interstellar Extinction Curves. VII. Milky Way Spectrophotometric Optical-through-ultraviolet Extinction and Its R-dependence
- E. Fitzpatrick, D. Massa, K. Gordon, R. Bohlin, G. Clayton
- PhysicsThe Astrophysical Journal
- 19 October 2019
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…
