The VLT-FLAMES Tarantula Survey XXI. Stellar spin rates of O-type spectroscopic binaries
O. H. Ramírez-Agudelo, H. Sana, S. E. de Mink +9
The initial distribution of spin rates of massive stars is a fingerprint of their elusive formation process. It also sets a key initial condition for stellar evolution and is thus…
The VLT-FLAMES Tarantula survey XX. The nature of the X-ray bright emission line star VFTS 399
J. S. Clark, E. S. Bartlett, P. S. Broos +12
The stellar population of the 30 Doradus star-forming region in the Large Magellanic Cloud contains a subset of apparently single, rapidly rotating O-type stars. The physical proce…
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 evolution of rotating very massive stars with LMC composition
K. Köhler, N. Langer, A. de Koter +8
We present a dense model grid with tailored input chemical composition appropriate for the Large Magellanic Cloud. We use a one-dimensional hydrodynamic stellar evolution code, whi…
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

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 IACOB project: II. On the scatter of O-dwarf spectral type -- effective temperature calibrations
S. Simón-Díaz, A. Herrero, C. Sabín-Sanjulián +5
We are now in an era of large spectroscopic surveys of OB-type stars. Quantitative spectroscopic analysis of these modern datasets is enabling us to review the physical properties…
Rotational velocities of single and binary O-type stars in the Tarantula Nebula
O. H. Ramírez-Agudelo, H. Sana, A. de Koter +15
Rotation is a key parameter in the evolution of massive stars, affecting their evolution, chemical yields, ionizing photon budget, and final fate. We determined the projected rotat…

Joachim M. Bestenlehner, Götz Gräfener, Jorick S. Vink +12
The evolution and fate of very massive stars (VMS) is tightly connected to their mass-loss properties. Their initial and final masses differ significantly as a result of mass loss.…
The VLT-FLAMES Tarantula Survey. XIII: On the nature of O Vz stars in 30 Doradus
