Ultra-Massive Stars are Products of Cannibalism
In 2010 scientists discovered four “monster” sized stars, with the heaviest more than 300 times as massive as our Sun. Despite their incredible luminosity, these exotic objects—located in the giant star cluster R136 in the nearby galaxy the Large Magellanic Cloud—have so far been found nowhere else. Now, a group of astronomers at the Univ. of Bonn have a new explanation: the ultramassive stars were created from the merger of lighter stars in tight binary systems. The team presents their results in the journal Monthly Notices of the Royal Astronomical Society.
