42 on a hertzsprung-russell diagram, where would you find stars that are cool and luminous?

Hertzsprung-Russell diagram, also called H-R diagram, in astronomy, graph in which the absolute magnitudes (intrinsic brightness) of stars are plotted against their spectral types (temperatures). Of great importance to theories of stellar evolution, it evolved from charts begun in 1911 by the Danish astronomer Ejnar Hertzsprung and independently by the U.S. astronomer Henry Norris Russell. Note that this important feature of the stellar population -- that cool stars come in two sizes -- is a simple consequence of the gap between the bright and faint groups on the right-hand side of this diagram. Both Hertzsprung and Russell noticed this gap between the luminous and feeble red stars, and decided to give names to the two groups.

So the right way to think about an H-R Diagram. It is telling us that a star's color (or temperature) and its luminosity are related. Blue stars are more luminous than red stars. To find this out, though, we have to know the distances to the stars. Remember the star catalog we showed one page of in the last lecture, from the Nearby Stars catalog.

By definition a star of magnitude 1 is 100 × brighter than one of magnitude 6. Our Sun has an absolute magnitude of + 4.8. Possible axes for a Hertzsprung-Russell Diagram. Note how the temperature scale is reversed on the horizontal axis. Also take care if using magnitude to work upwards to negative values. 21) On a Hertzsprung-Russell diagram, where would you find stars that are cool and luminous?. A) upper right. B) lower right.

The white dwarf will slowly cool over time, like a dying ember in a fire, becoming fainter and redder as it radiates away its heat. In this exercise, you are going to use an Hertzsprung-Russell Diagram to determine the luminosity and temperature of stars.

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. The giant branch and supergiant stars lie above the main sequence, and white dwarfs are found below it.
