The VLT-FLAMES Tarantula Survey. XXIX. Massive star formation in the local 30 Doradus starburst

F. R. N. Schneider, O. H. Ramírez-Agudelo, F. Tramper +24

The 30 Doradus (30 Dor) nebula in the Large Magellanic Cloud (LMC) is the brightest HII region in the Local Group and a prototype starburst similar to those found in high redshift…

Spectroscopic and physical parameters of Galactic O-type stars. III. Mass discrepancy and rotational mixing

Nevena Markova, Joachim Puls, Norbert Langer

Massive stars play a key role in the evolution of the Universe. Our goal is to compare observed and predicted properties of single Galactic O stars to identify and constrain uncert…

The mass discrepancy problem in O stars of solar metallicity. Does it still exist?

N. Markova, J. Puls

Using own and literature data for a large sample of O stars in the Milky Way, we investigate the correspondence between their spectroscopic and evolutionary masses, and try to put…

Physics of mass loss in massive stars

J. Puls, J. O. Sundqvist, N. Markova

We review potential mass-loss mechanisms in the various evolutionary stages of massive stars, from the well-known line-driven winds of O-stars and BA-supergiants to the less-unders…

The rotation rates of massive stars: How slow are the slow ones?

J. O. Sundqvist, S. Simon-Diaz, J. Puls +1

Context: Rotation plays a key role in the life cycles of stars with masses above 8 Msun. Hence, accurate knowledge of the rotation rates of such massive stars is critical for under…

The VLT-FLAMES Tarantula Survey XII. Rotational velocities of the single O-type stars

O. H. Ramírez-Agudelo, S. Simón-Díaz, H. Sana +15

Aims. Using ground based multi-object optical spectroscopy obtained in the framework of the VLT-FLAMES Tarantula Survey (VFTS), we aim to establish the (projected) rotational veloc…
