Stellar winds of O-type stars traced by high ionization fine-structure emission lines with JWST/MIRI
Calum Hawcroft, David R. Law, Linda J. Smith +8
We investigate the presence of high ionization fine-structure emission lines across a range of 22 OB-type stars observed with JWST-MIRI as part of calibration programmes and the WI…
Probing Thin Winds in Massive OB Stars of the SMC with JWST/NIRSPEC Br-alpha Spectroscopy
Miriam Garcia, Alexander W. Fullerton, Francisco Najarro +12
Mass loss is a key physical process in the evolution of massive stars, the impact of which propagates into galactic evolution, population synthesis models, the interpretation of hi…
The UV Legacy Library of Young Stars as Essential Standards (ULLYSES) Large Director's Discretionary Program with Hubble. I. Goals, Design, and Initial Results
Julia Roman-Duval, William J. Fischer, Alexander W. Fullerton +44
Specifically selected to leverage the unique ultraviolet capabilities of the Hubble Space Telescope, the Hubble Ultraviolet Legacy Library of Young Stars as Essential Standards (UL…
JWST/MIRI detection of [Ne V], [Ne VI], and [O IV] wind emission in the O9V star 10 Lacertae
David R. Law, Calum Hawcroft, Linda J. Smith +5
We report the detection of broad, flat-topped emission in the fine-structure lines of [Ne V], [Ne VI], and [O IV] in mid-infrared spectra of the O9 V star 10 Lacertae obtained with…
Massive star winds interacting with magnetic fields on various scales
A. David-Uraz, V. Petit, C. Erba +3
One of the defining processes which govern massive star evolution is their continuous mass loss via dense, supersonic line-driven winds. In the case of those OB stars which also ho…
FUSE, STIS, and Keck spectroscopic analysis of the UV-bright star vZ 1128 in M3 (NGC 5272)
Pierre Chayer, William V. Dixon, Alexander W. Fullerton +2
We present a spectral analysis of the UV-bright star vZ 1128 in M3 based on observations with the Far Ultraviolet Spectroscopic Explorer (FUSE), the Space Telescope Imaging Spectro…
Confirmation of the magnetic oblique rotator model for the Of?p star HD 191612
G. A. Wade, I. D. Howarth, R. H. D. Townsend +11
This paper reports high-precision Stokes V spectra of HD 191612 acquired using the ESPaDOnS spectropolarimeter at the Canada-France-Hawaii Telescope, in the context of the Magnetis…
New insights into the nature of the SMC WR/LBV binary HD 5980
C. Foellmi, G. Koenigsberger, L. Georgiev +14
We present the results of optical wavelength observations of the unusual SMC eclipsing binary system HD 5980 obtained in 1999 and 2004--2005. Radial velocity curves for the eruptin…
