Stellar life cycles and element formation

Space physics • Solar system and orbits

Key concepts

What you'll likely be quizzed about

  • Stars form from clouds of gas and dust known as nebulae.
  • Under the influence of gravity, regions within the nebula collapse, becoming denser and forming protostars.
  • As the protostar continues to accumulate mass, temperatures rise, eventually initiating nuclear fusion in its core.
  • This process transforms hydrogen into helium, releasing energy and producing light, which signals the birth of a new star.

How do protostars form?

Click to reveal answer

Protostars form when regions within a nebula collapse under gravity, leading to increased density and temperature.

Key notes

Important points to keep in mind

Stars form from collapsing nebulae.

Supernovae distribute heavy elements into space.

Nuclear fusion produces energy and elements.

Star evolution stages influence element types.

A red giant phase leads to changes in composition.
