SUMMARY:The rotation of massive stars with and without compact companions 
DESCRIPTION:The rotation of massive stars with and without compact companio
 ns \nProf. Norbert Langer\n\nMassive stars are generally fast rotators, ho
 wever, with significant  dispersion. We discuss the hypothesis that all OB
  stars are all born  with very similar spins, with slower and faster rotat
 ors being produced  by close binary evolution. We review supporting eviden
 ce from recent  observations of young and rich star clusters, from OB star
  surveys, and  from dense grids of detailed binary evolution models. We co
 nnect the OB  star spins with the likelihood of evolved/compact binary com
 panions, and  with the variety of the explosive end states of massive star
 s.\n \nYoutube: https://youtu.be/yJHMQFmLsGE
