What is a white dwarf?

Back

A white dwarf is a small, hot star that is near the end of its life cycle, typically formed from the remnants of a low to medium mass star after it has exhausted its nuclear fuel.

Front

How would you describe our sun?

Back

Our sun is considered an average star, which means it is not particularly large or small compared to other stars in the universe.

Front

What stage is our sun currently in?

Back

Our sun is currently in the Main Sequence stage, where it spends most of its life fusing hydrogen into helium.

Front

What are some names used for stars?

Back

Stars can be classified into various types, including neutron stars, supergiants, and white dwarfs.

Front

What happens to a low mass star after the main sequence?

Back

After the main sequence, a low mass star becomes a red giant as it expands and cools after exhausting its hydrogen fuel.

Front

What is a red giant?

Back

A red giant is a late stage in the life cycle of a star, characterized by a large size and a reddish color, occurring after the star has exhausted its hydrogen fuel.

Front

What is a supergiant star?

Back

A supergiant star is an extremely large star that has a much greater luminosity than a giant star, often at least 100 times the radius of the sun.

Front

What is a neutron star?

Back

A neutron star is the remnants of a supernova explosion, composed almost entirely of neutrons, and is incredibly dense.

Front

What is a protostar?

Back

A protostar is an early stage in the formation of a star, where gas and dust collapse under gravity to form a dense core that will eventually ignite nuclear fusion.

Front

What is a black dwarf?

Back

A black dwarf is a theoretical stellar remnant that occurs when a white dwarf has cooled sufficiently that it no longer emits significant heat or light.
