'Spinstars' - First Polluters of the UniversePotsdam, Geramny (SPX) Apr 28, 2011 From the analysis of the chemical composition of some of the oldest stars in our Galaxy, an international team of astronomers led by Cristina Chiappini from the Leibniz-Institut fuer Astrophysik Potsdam (AIP) and the Instituto Nazionale di Astrofisica (INAF) presents new clues on the nature of the first stellar generations in our Universe. "We think that the first generations of massive stars were very fast rotators - that's why we called them spinstars", explains Chiappini. Their findings will be ... read more |
