HR Diagram

Front

What is the HR Diagram?

Back

The HR Diagram (Hertzsprung-Russell Diagram) is a scatter plot that shows the relationship between the luminosity and temperature of stars.

Front

What factors affect the luminosity of a star?

Back

The luminosity of a star is affected by its size and surface temperature.

Front

How does the size of a star influence its luminosity?

Back

Larger stars have greater luminosity because they can produce more energy through nuclear fusion.

Front

What is the relationship between surface temperature and luminosity in stars?

Back

Higher surface temperature generally leads to higher luminosity.

Front

What type of stars are Red Giants?

Back

Red Giants are large stars that have expanded and cooled, resulting in a lower surface temperature and higher luminosity compared to smaller stars.

How do Red Supergiants compare to Red Giants in terms of luminosity?

Back

Red Supergiants have a higher luminosity than Red Giants.

Front

What are White Dwarfs?

Back

White Dwarfs are small, dense stars that are the remnants of stars that have exhausted their nuclear fuel.

How does the surface temperature of White Dwarfs compare to Red Supergiants?

Back

The surface temperature of White Dwarfs is higher than that of Red Supergiants.

Front

What types of stars are found in the Main Sequence?

Back

The Main Sequence contains stars that are in a stable phase of hydrogen burning, including both low mass and high mass stars.

Front

What characterizes Main Sequence - low mass stars?

Back

Main Sequence - low mass stars are cooler and less luminous than their high mass counterparts.
