What is the Hertzsprung-Russell diagram?

Back

A graphical representation of stars that plots their brightness against their temperature, helping to classify stars into different categories.

Front

What type of star is a blue supergiant?

Back

A very bright and massive star that is much larger than the Sun and has a high temperature.

Front

What are the characteristics of a white dwarf?

Front

What is a red giant?

Back

A large, luminous star that has expanded and cooled, typically found in the later stages of stellar evolution.

Front

How does the temperature of a red giant compare to that of a white dwarf?

Back

A red giant is cooler than a white dwarf.

Front

What stage comes after the main sequence in a star's life cycle?

Back

The red giant stage.

Front

What is the main sequence?

Back

The main sequence is a continuous and distinctive band of stars that appears on plots of stellar color versus brightness, where stars spend most of their life.

Front

What is the first stage in the life cycle of a star?

Back

Nebula.

Front

What is the final stage of a low-mass star's life cycle?

Back
