In a large molecular cloud that gives birth to a cluster of stars, there will be a range of masses for the protostars that form. Due to the more massive stars having faster fusion rates, they will complete their protostar stage and reach the main sequence first, while the lower mass stars may take longer. As a result, a few massive stars will form, live, and die before the majority of the star cluster even complete their protostar stage.
