Understanding the progenitors of core-collapse supernovae (SNe) and their population statistics is a key ingredient for many current studies in astronomy, but as yet this remains elusive. Using the MESA stellar evolution code, we study the dependence of the lower mass limit for making core-collapse SNe a function of initial stellar metallicity. We find that this mass limit is smallest at [Z] ≈ −2 with a value of ∼8.3 M☉. At [Z] = 0 the limit is ∼9.5 M☉ and continues to rise with higher…
