What mass typically starts the life of a Core Collapse Supernova progenitor star?

Exceeding about eight times the Sun's mass ($M_{\odot}$)

A core collapse supernova (CCSN) is the violent final event marking the termination of life for stars that are significantly more massive than the Sun. Specifically, the text establishes that the progenitors for these types of explosions are stars that begin their lives with masses typically exceeding approximately eight times the mass of the Sun ($M_{\odot}$). This critical mass threshold dictates the star's fate, as only stars above this size possess the necessary gravitational force and core temperatures to progress through the fusion stages all the way to iron formation, setting the stage for gravitational collapse. Stars significantly less massive than this threshold end their lives via quieter mechanisms, such as puffing off layers to form planetary nebulae, rather than undergoing core collapse and explosion.
