Hertzsprung-russell Diagram

Hertzsprung-russell plat The Hertzsprung-Russell Diagram or, the H-R Diagram for short, is a graph which plots stars check to their temperature and absolute magnitude. This graph reveals a pattern, which in fact is kind of interesting. The H-R Diagram is named for the both astronomers, Ejnar Hertzsprung and Henry Russell, who discovered this pattern of stars. These two astronomers independently discovered that comparing magnitudes and spectral class (color) of stars yielded a lot of information about them. One key determination of the H-R diagram is to show the relationship between temperature and absolute magnitude of stars.

The type of temperature measurement used is Kelvin, where the zero point is match to -273.16 C. On the H-R Diagram, the temperature of degrees Kelvin ranges from 3,000 to 30,000. The absolute magnitude of stars on the H-R Diagram ranges from +15 to -10. Absolute magnitude is how bright stars would appear if they were positioned at 32.6 light years away from eart...If you want to get a full essay, order it on our website: Orderessay
