... (b) Type II: their spectrum contains prominent hydrogen lines; they originate from the explosion of a single star. 5. Type I supernovae are divided into three subclasses: (a) Type Ib, and Ic are caused by massive stars that have lost different proportions of their outer layers before exploding. (b) ...

For low mass stars, the relatively weak dependence of pp-cycle energy generation on temperature allows more of the star to be involved in nuclear reactions.
