What will eventually happen to white dwarf stars?

Back

They will slowly burn or fuse carbon, dim, and cool to form black dwarf crystallized diamond stars.

To what extent do red giant stars expand their outer layers?

Back

Red giant stars expand their outer layers to about the orbit of Mars; supergiants expand to the orbit of Jupiter.

What is the primary process that occurs in the core of a red supergiant star?

Back

The primary process is the fusion of carbon and heavier elements.

Front

What is the life cycle of a star with a mass greater than 10 solar masses?

Back

It evolves into a red supergiant, undergoes supernova, and may form a neutron star or black hole.

Front

What is the significance of a star's mass in its life cycle?

Back

A star's mass determines its temperature, luminosity, and the stages it will go through in its life cycle.

What is the difference between a white dwarf and a black dwarf?

Back

A white dwarf is a hot, dense remnant of a star, while a black dwarf is a theoretical end state that occurs when a white dwarf cools down completely.
