TL;DR: The VLT-FLAMES Tarantula Survey (VFTS) as discussed by the authors is an ESO Large Programme that has obtained multi-epoch optical spectroscopy of over 800 massive stars in the 30 Doradus region of the Large Magellanic Cloud (LMC).

Journal ArticleDOI
The IACOB project - I. Rotational velocities in northern Galactic O- and early B-type stars revisited. The impact of other sources of line-broadening
TL;DR: In this paper, a combined Fourier Transform (FT)+ goodness of fit (GOF) methodology was proposed for the line-broadening characterization in Galactic OB-type stars, and the authors used this tool to investigate the impact of macroturbulent and microturbulent broadenings on v sin i measurements.
Journal ArticleDOI
The VLT-FLAMES Tarantula Survey - XII. Rotational velocities of the single O-type stars

TL;DR: In this article, the authors measured projected rotational velocities, ν_esini, by means of a Fourier transform method and a profile fitting method applied to a set of isolated spectral lines.

TL;DR: In this article, the authors determined the recent formation history and the initial mass function (IMF) of massive stars in 30 Doradus on the basis of spectroscopic observations of 247 stars more massive than 15 solar masses.
