Abstract:
The VLT-FLAMES Tarantula Survey (VFTS) 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).
Here we introduce our scientific motivations and give an overview of
the survey targets, including optical and near-infrared photometry and
comprehensive details of the data reduction. One of the principal
objectives was to detect massive binary systems via variations in
their radial velocities, thus shaping the multi-epoch observing
strategy. Spectral classifications are given for the massive
emission-line stars observed by the survey, including the discovery of
a new Wolf-Rayet star (VFTS 682, classified as WN5h), 2' to the
northeast of R136. To illustrate the diversity of objects encompassed
by the survey, we investigate the spectral properties of sixteen
targets identified by Gruendl & Chu (2009, Cat. J/ApJS/184/172) from
Spitzer photometry as candidate young stellar objects or stars with
notable mid-infrared excesses. Detailed spectral classification and
quantitative analysis of the O- and B-type stars in the VFTS sample,
paying particular attention to the effects of rotational mixing and
binarity, will be presented in a series of future articles to address
fundamental questions in both stellar and cluster evolution.
Description:
The Tarantula Survey employs three modes of the Fibre Large Array
Multi-Element Spectrograph (FLAMES) instrument on the VLT:
Medusa-Giraffe, ARGUS-Giraffe and UVES.
Most of the Medusa observations were obtained over the period 2008
October to 2009 February.
