Wolf-Rayet stars possess strong stellar winds and are deficient in hydrogen-at least when compared with other stars. They're easily recognizable by their stellar signatures. That's why scientists have long wondered whether these stars explode as type IIb, Ib or Ic supernovae. Unfortunately, little d...
