... Remember, the orbits in an elliptical galaxy are fairly random, so even if we focus on one area there will be a range of Doppler shifted lines from the stars that are moving towards and away from us at different speeds. These all combine (they sort of add together) to make a broadened line. The broa ...

R136a1
RMC 136a1 (usually abbreviated to R136a1) is a Wolf-Rayet star located at the center of R136, the central condensation of stars of the large NGC 2070 open cluster in the Tarantula Nebula. It lies at a distance of about 50 kiloparsecs (163,000 light-years) in the Large Magellanic Cloud. It has the highest mass and luminosity of any known star, at 265 M☉ and 8.7 million L☉, and also one of the hottest at over 50,000 K.
