Life Cycle of a Star and H-R Diagram GN

Front

What is a supernova?

Back

An exploding star that occurs at the end of a star's life cycle, resulting in a massive explosion.

Front

What does the center of the H-R diagram represent?

Back

Stars with medium luminosity.

Front

What determines the path a star takes during its life cycle?

Back

The mass of the star.

Front

What is a nebula?

Back

A cloud of dust and gas in space where stars are born.

Front

Where are stars born?

Back

In nebulae.

Front

What is the H-R diagram?

Back

A graph that plots stars according to their luminosity and temperature.

Front

What is luminosity?

Back

The total amount of energy emitted by a star per second.

Front

What is the relationship between a star's mass and its life cycle?

Back

More massive stars have shorter life cycles and end in supernovae, while less massive stars live longer.

Front

What is a black hole?

Back

A region in space where the gravitational pull is so strong that nothing, not even light, can escape from it.

Front

What is a protostar?

Back

An early stage in the formation of a star, where gas and dust collapse under gravity.
