VFTS 102

VFTS 102 is a star located in the Tarantula nebula, a star forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The peculiarity of this star is its projected equatorial velocity of ~600 km/s (about 2.000.000 km/h), making it the fastest rotating massive star known. The resulting centrifugal force tends to flatten the star; material can be lost in the loosely bound equatorial regions, allowing for the formation of a disk. The spectroscopic observations seem to confirm this, and the star is classified as Oe, possibly due to emission from such an equatorial disk of gas.
