... All previous such superstars have been found along with many companion stars in the centres of crowded star clusters. The star is known as VFTS 682 from the VLT-FLAMES Tarantula Survey catalogue of the European Southern Observatory's Very Large Telescope (VLT) located at Paranal in Chile by means of the attached FLAMES instrument. ... Although VFTS 682 seems to be alone now it is not very far away from a very rich star cluster known as RMC 136 that contains several similar superstars. ...

Why areNuclear Star Clusters interesting? 1) Many -- if not all ­ nuclear star clusters appear to be young, or at least have a young population of stars. ... 3) If nuclear clusters indeed form in the galaxy center, their impact on the dynamics of stars and gas in the central region of the host galaxy needs to be understood, because it can potentially influence the galaxy morphology. For example, it has been suggested that nuclear clusters can destroy stellar bars and thus form galaxy bulges. ...
