==End of Supergiants==

All spectral types of supergiants can end their lives as [[supernova]] if their cores' mass exceed 1.4 solar masses (known as the [[Chandrasekhar limit]]).<ref>http://adsabs.harvard.edu/abs/1987ApJ...323..140L</ref>  It was once thought that only red supergiants could end their lives this way.  This was disproved with occurrence of Supernova 1987A in the [[Large Magellanic Cloud]] on February 23, 1987, when it was discovered the progenitor star was a B3 class, blue supergiant.<ref>http://adsabs.harvard.edu/abs/arXiv:0705.3066</ref>  Supergiants that have a core mass of less then 1.4 solar masses will end their lives as a [[white dwarf]].
