Hertzsprung-Russell draw The Hertzsprung-Russell diagram or, the H-R Diagram for short, is a graph which plots stars patch up to their temperature and absolute order. This graph reveals a pattern, which in fact is quite interesting. The H-R Diagram is named for the cardinal astronomers, Ejnar Hertzsprung and Henry Russell, who discovered this pattern of stars. These twain astronomers independently discovered that comparing magnitudes and spectral class (color) of stars yielded a lot of information about them. One key number 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 adequate 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...If you want to get a full essay, order it on our website:
