On a hertzsprung russell diagram where would you find stars that are cool and dim. The giant branch and supergiant stars lie above the main sequence and white dwarfs are found below it. How does the hertzsprung russell diagram help us understand stars. A lower right b lower left c upper left d upper right.

B on a hertzsprung russell. A star in the lower left corner of the diagram would be hot and dim. C apparent brightness of the star in our sky.

The h r diagram as its known for short plots a stars luminosity its true brightness against its surface temperature. The effective temperature of a star is plotted on the horizontal axis of an h r diagram. Stars on the main sequence that have the greatest mass.

By far the most prominent feature is the main sequence grey which runs from the upper left hot luminous stars to the bottom right cool faint stars of the diagram. On a hertzsprung russell diagram where would you find stars that are cool and from astr 100lg at university of southern california. The group called the main sequence extends in a rough diagonal from the upper left of the diagram hot bright stars to the lower right dim and cool.

Stars along the main sequence are fusing hydrogen into helium in their cores the rate of hydrogen fusion depends on a stars mass. Interactive lab lets see how good you are at reading the hr diagram. 5 on the h r diagram where can you find cool and dim stars.

One quirk here is that the temperature is plotted in reverse order with high temperature around 30000 40000 k on the left and the cooler temperature around 2500 k on the right. A star in the lower right corner of the diagram would be cold and dim. Stars with the largest radii.

The giant sequence of large bright though cool stars appears in the upper right and the white dwarfs dim small and hot lie in the lower left. On a hertzsprung russell diagram where would we find stars that are cool and dim. A upper right b lower right c upper left d lower left answer.

You observe a star in the disk of the milky way and you want to plot the star on an h r diagram. The relationship between luminosity and temperature has a direct correlation to a stars mass. On this diagram 95 percent of stars including the sun fall into a band that slopes diagonally from hot bright blue stars like regulus to cool dim red stars like proxima centauri.

Classifying stars the hertzsprung russell diagram. B distance to the star. Click the diagram below we have five stars.
