Stellar Evolution
Muhtasari
Stars are born, they shine for millions or billions of years, and eventually they die. The path a star takes depends on one thing above all: its mass. Our Sun will end quietly as a white dwarf; a star ten times more massive will explode as a supernova.
In this lesson you will learn how to classify stars by colour and temperature, and trace the life cycle of both Sun-like and massive stars from nebula to final remnant.
Malengo
- Understand how stars can be classified according to their colour
- Know that a star's colour is related to its temperature
- Describe the evolution of stars of similar mass to the Sun through the stages: nebula, star (main sequence), red giant, white dwarf
- Describe the evolution of stars with a mass larger than the Sun
