VLT-FLAMES Tarantula Survey
VLT-FLAMES Tarantula Survey (VFTS) is an astronomical survey conducted by European Southern Observatory (ESO). It obtained multi-epoch optical spectroscopy of over 800 massive stars in the Tarantula Nebula star-forming region, within the Large Magellanic Cloud (LMC). The survey focused on O-type, B-type, and Wolf–Rayet stars to investigate stellar evolution, binarity, and dynamical processes in a low-metallicity environment representative of conditions in the early universe. Observations were carried out from 2008 to 2009 using the FLAMES multi-object spectrograph on the Very Large Telescope (VLT) in Chile.[1][2][3][4]
Notable Stars
There are some unique star systems discovered by the VFTS Survey
VFTS 16 and VFTS 72 are notable massive runaway star in located in the Tarantula Nebula region.[5]
VFTS 102 is a notable star system for it's peculiarity as its projected equatorial velocity of ~610 km/s (about 2,000,000 km/h), making it the second fastest rotating massive star known alongside VFTS 285 (609 km/s), and preceded only by the WO star WR 142 which has a rotational velocity of 1000 km/s.[6][7][8]
VFTS 243 is notable for containing a stellar black hole and an O-type star in the system.[9][10]
VFTS 352 is a notable O-type contact binary star system as it is the most massive and earliest spectral type overcontact system known.[11][12]
VFTS 682 is a notable star system containing one of the most massive and luminous Wolf-Rayet star.[13]
