H-R Diagram Stations

Front

What does the effective temperature of a star relate to?

Back

The effective temperature of a star is related to its color.

Front

What relationship does the HR Diagram show?

Back

The HR Diagram shows the relationship between a star's surface temperature and its absolute magnitude.

Front

What can be inferred about stars of different colors?

Back

Stars of different colors have different temperatures.

Front

What happens to main sequence stars as they increase in temperature?

Back

Main sequence stars decrease in brightness while they decrease in temperature.

Front

What celestial body is known for its intense pull of gravity?

Back

A black hole is known for its intense pull of gravity.

Front

What is the main sequence in the H-R Diagram?

Back

The main sequence is a continuous band of stars that ranges from hot, luminous stars to cool, dim stars.

Front

How does luminosity relate to a star's temperature?

Back

Generally, as a star's temperature increases, its luminosity also increases.

Front

What is absolute magnitude?

Back

Absolute magnitude is the measure of a star's intrinsic brightness as it would appear at a standard distance of 10 parsecs.

Front

What is the significance of color in stars?

Back

The color of a star indicates its surface temperature; blue stars are hotter, while red stars are cooler.

Front

What type of star is found at the top right of the H-R Diagram?

Back

Red supergiants are found at the top right of the H-R Diagram.
