What type of explosive event marks the dramatic demise of a star that has gone through the supergiant phase (initial mass $> 8 ext{M}_ ext{odot}$)?
Answer
A Type II supernova explosion
Once core fusion processes cease in these massive stars, the core collapses catastrophically, leading directly to a Type II supernova explosion.
