Question

Arrange these phases in the partial life cycle of a star in order, starting with the earliest event.

i.) In, heavy stars, the core contracts, pulling the outer layer inward. Hydrogen fusion begins in the outer shell. The outer shell expands, and the light generated increases.

ii.) The hydrogen supply in the core starts to run out. The outer shell expands, cool down, and starts to glow red.

iii.) Stars that have roughly more than three times the mass of our sun becomes black holes.
