26th July 2012"Binary Interaction Dominates the Evolution of Massive Stars"
In the Science issue from 27th July 2012, we show that the evolution of the most massive stars in the Universe,
the O-stars, is dominated by binary interactions. Observations of up to ten years with the UVES spectrograph at
the Very Large Telescope (VLT) revealed that almost three quarters of all O-stars within six Galactic star clusters
have a close companion such that 70% of all O-stars will exchange mass with their companion and only 30% of all
O-stars are effectively single stars. This has severe consequences for populations of massive stars e.g. in
star forming galaxies, supernova types and gamma ray bursts.
To find out more, have a look into the paper and the press releases.
