Hertzsprung-Russell Diagram

Hertzsprung-Russell draw The Hertzsprung-Russell draw or, the H-R Diagram for short, is a graph which plots stars approve to their temperature and absolute order. This graph reveals a pattern, which in fact is sort of interesting. The H-R Diagram is named for the cardinal astronomers, Ejnar Hertzsprung and Henry Russell, who discovered this pattern of stars. These 2 astronomers independently discovered that comparing order of magnitudes and spectral class (color) of stars yielded a lot of information about them. One key subroutine 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 nice 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: OrderCustomPaper.com
