What characterizes the progenitor stars believed to be responsible for generating the most energetic superluminous events via gravitational collapse?

Answer

Exceeding 100 times the mass of the Sun

The Massive Progenitors theory suggests the initial star was exceptionally massive, perhaps exceeding 100 solar masses, leading to collapse and the formation of a compact object.
