SUMMARY:On the fate of the most massive stars
DESCRIPTION:On the fate of the most massive stars\nDr. Jorick Vink\n\nRadia
 tion-driven mass loss largely determines the life expectancy of massive st
 ars.  I will present our most recent mass-loss predictions for massive sta
 rs, which are obtained from Monte-Carlo multi-line radiative transfer calc
 ulations.  I will show how these predictions are expected to change as a f
 unction of metallicity (and redshift!) and confront the results against da
 ta from the VLT FLAMES large programme of massive stars.  Finally, I discu
 ss some of the more intricate aspects of the physics of radiation-driven o
 utflows, emphasizing the relevance for the rotational evolution of massive
  stars into the Luminous Blue Variable phase.  This is shown to lead to so
 me rather unexpected results... in particular for the progenitors of super
 novae and gamma-ray bursts -- calling for some major paradigm shifts of ev
 en our most basic framework of massive star evolution.
