Micro-turbulence across the Hertzsprung-Russell diagram. Observational constrains for stars in the MW
N. Markova, M. Cantiello, L. Grassitelli
We assemble a homogeneous database of precise and consistent determinations of effective temperature, surface gravity, projected rotational rate, and macro- and micro-turbulent vel…
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…
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 XIV. The O-Type Stellar Content of 30 Doradus
N. R. Walborn, H. Sana, S. Simon-Diaz +6
Detailed spectral classifications are presented for 352 O-B0 stars in the VLT-FLAMES Tarantula Survey, of which 213 O-type are of sufficient quality for further morphological analy…
Wind structure in late-B supergiants
N. Markova, H. Markov
Extended spectroscopic datasets of several late-B stars of luminosity class Ia revealed the presence of similar peculiarities in their H alpha profiles, which might be interpreted…
