The VLT-FLAMES Tarantula Survey: XXVIII. Nitrogen abundances for apparently single dwarf and giant B-type stars with small projected rotational velocities
P. L. Dufton, A. Thompson, P. A. Crowther +13
Previous analyses of the spectra of OB-type stars in the Magellanic Clouds have identified targets with low projected rotational velocities and relatively high nitrogen abundances.…
The Origin of B-Type Runaway Stars: Non-LTE Abundances as a Diagnostic
Catherine M. McEvoy, Philip L. Dufton, Jonathan V. Smoker +4
There are two accepted mechanisms to explain the origin of runaway OB-type stars: the Binary Supernova Scenario (BSS), and the Cluster Ejection Scenario (CES). In the former, a sup…
Broad Balmer Wings in BA Hyper/Supergiants Distorted by Diffuse Interstellar Bands: Five Examples in the 30 Doradus Region from the VLT-FLAMES Tarantula Survey
Nolan R. Walborn, Hugues Sana, Christopher J. Evans +11
Extremely broad emission wings at H and H have been found in VFTS data for five very luminous BA supergiants in or near 30 Doradus in the Large Magellanic Cloud. The profiles…
Early-type stars observed in the ESO UVES Paranal Observatory Project - V. Time-variable interstellar absorption
Catherine M. McEvoy, Jonathan V. Smoker, Philip L. Dufton +6
The structure and properties of the diffuse interstellar medium (ISM) on small scales, sub-au to 1 pc, are poorly understood. We compare interstellar absorption-lines, observed tow…
The VLT-FLAMES Tarantula Survey XVIII. Classifications and radial velocities of the B-type stars
C. J. Evans, M. B. Kennedy, P. L. Dufton +14
We present spectral classifications for 438 B-type stars observed as part of the VLT-FLAMES Tarantula Survey (VFTS) in the 30 Doradus region of the Large Magellanic Cloud. Radial v…
The VLT-FLAMES Tarantula Survey XIX. B-type Supergiants - Atmospheric parameters and nitrogen abundances to investigate the role of binarity and the width of the main sequence
C. M. McEvoy, P. L. Dufton, C. J. Evans +19
TLUSTY non-LTE model atmosphere calculations have been used to determine atmospheric parameters and nitrogen (N) abundances for 34 single and 18 binary B-type supergiants (BSGs). T…
The VLT-FLAMES Tarantula Survey - XI. A census of the hot luminous stars and their feedback in 30 Doradus
E. I. Doran, P. A. Crowther, A. de Koter +16
We compile the first comprehensive census of hot luminous stars in the 30 Doradus (30 Dor) star forming region of the LMC. The census extends to a radius of 10arcmin (150pc) from t…
The VLT-FLAMES Tarantula Survey X: Evidence for a bimodal distribution of rotational velocities for the single early B-type stars
P. L. Dufton, N. Langer, P. R. Dunstall +12
Aims: Projected rotational velocities (\vsini) have been estimated for 334 targets in the VLT-FLAMES Tarantula survey that do not manifest significant radial velocity variations an…
