Question
Based on your knowledge of stars and the H-R diagram, which is the correct sequence of a star's life cycle.Giant > Main Sequence > White DwarfWhite Dwarf > Main Sequence > GiantMain Sequence > Giant > White DwarfMain Sequence > White Dwarf > Supergiant
Solution
The correct sequence of a star's life cycle is: Main Sequence > Giant > White Dwarf.
Here's a step-by-step explanation:
-
Main Sequence: Stars spend the majority of their life in this stage, where they are fusing hydrogen into helium in their cores. Our Sun is currently in this stage.
-
Giant: As stars exhaust their hydrogen fuel, they leave the main sequence and become giants. In this stage, the star expands and cools. It begins to fuse helium into heavier elements.
-
White Dwarf: After the giant phase, stars shed their outer layers and leave behind a hot core, known as a white dwarf. Over billions of years, the white dwarf cools and fades away.
