What is the typical initial mass range for stars that undergo pair-instability supernovae?
Answer
$140$ to $250 M_ ext{ extdollar}$ (with low metallicity)
Stars starting with initial masses between $140$ and $250 M_ ext{ extdollar}$ (and low metallicity) can experience pair-instability supernovae, which are hyper-energetic events that completely tear the star apart, leaving no compact remnant.
