Hertzsprung-Russell (HR) diagram classifies stars based on their luminosity (brightness) and temperature. This diagram allows astronomers to categorize stars into main sequence, giants, supergiants, white dwarfs, and other classes based on their positions in the diagram. It provides insights into the life cycle and evolutionary stage of stars.

Does the H-R diagram classify stars by the amount of heat they create?

No, the Hertzsprung-Russell (H-R) diagram classifies stars based on their luminosity (brightness) and temperature. It shows the relationship between a star's temperature and luminosity, allowing astronomers to categorize stars into different groups based on their color, size, and stage of evolution.


What does Hertzsprung-Russell diagram graph?

The Hertzsprung-Russell diagram graphs stars' luminosity (brightness) against their surface temperature (color or spectral type). This diagram helps astronomers study the relationships between a star's temperature, size, age, and evolutionary stage.


Does An HR diagram plots a stars luminosity and surface temperature?

Yes, an HR diagram plots a star's luminosity (brightness) against its surface temperature, also known as color or spectral type. This graph shows the relationship between these two characteristics for different stars, allowing astronomers to classify and study them.


A graph used by scientists that shows stars grouped by size is called the?

Hertzsprung-Russell diagram. This diagram plots a star's luminosity against its temperature (or color), allowing scientists to classify stars by size, brightness, and lifecycle stage.


What is a graph that shows relationship between a stars magnitude and temperature?

The Hertzsprung-Russell (HR) diagram is a graph that shows the relationship between a star's magnitude (luminosity) and temperature. It plots stars based on their color (temperature) and brightness (magnitude), allowing astronomers to classify stars and understand their evolutionary stage.
