Comparison between the starburst age and the CCSN subtype. Upper panel: type distribution of classified CCSNe compared to our SED modelled global age of the host starburst at the central regions of our sample LIRGs. Host galaxy extinctions of the SNe are indicated by the sizes of the circles; unknown (and likely small) extinction cases are indicated by squares. The symbol colours indicate the CCSN subtype classifications. The events are indicated with closed and open symbols based on their estimated host CCSN rate above and below 0.5 CCSN yr⁻¹, respectively. Lower panel: simplified cumulative distribution presentation of the upper panel data of the Type IIb/Ib/Ic/Ibn and Type II/IIn samples of CCSNe. The data suggests that H-poor and H-rich CCSNe come from very young (≲30 Myr) and older (≳30 Myr) starbursts, respectively.
