The Disappearance of the Red Supergiant Progenitor of Supernova 2008bk

Name: Work Video:
Duration: 3 min 30 s
Description: Massive stars end their lives in spectacular supernova explosions. Identifying the progenitor star is a test of stellar evolution and explosion models. Here we show that the progenitor star of the supernova SN 2008bk has now disappeared, which provides conclusive evidence that this was the death of a red supergiant star.
