Diagram showing the spectral class and luminosity of stars
Diagram showing the spectral class and luminosity of stars. The diagram was named The Hertzsprung-Russell Diagram, or the H-R diagram for short. At the beginning of the 20th century two astronomers found that if stars were plotted on a diagram with their luminosity (brightness) on one axis, and their spectral class on the other, that stars formed three distinct groups. The largest group, the Main Sequence Stars, is where 90% of the stars are found. These stars are fusing hydrogen into helium in their cores. This group propagates diagonally from the upper left corner, down to the right corner. The group below the main sequence is the White Dwarfs, which is a group of small, earth-sized stellar remnants. The third group, which is found above the main sequence is that of the giants.
Stars appear on a specific place on the main sequence depending on their mass and age. The mass determines when it will leave the main sequence.The H-R diagram is a significant tool for astronomers, when it comes to understanding stellar evolution

EDITORS COMMENTS
This print showcases a remarkable diagram known as The Hertzsprung-Russell Diagram, or the H-R diagram for short. Created at the beginning of the 20th century by two visionary astronomers, this diagram revolutionized our understanding of stars. By plotting stars based on their luminosity and spectral class, three distinct groups emerged. The largest group, occupying a prominent position along a diagonal line from the upper left to the lower right corner, is called Main Sequence Stars. These magnificent celestial bodies make up an astounding 90% of all stars and are engaged in fusing hydrogen into helium within their cores. Beneath the main sequence lies another group known as White Dwarfs. These small remnants resemble Earth in size but possess extraordinary cosmic significance. Above the main sequence resides yet another awe-inspiring group: giants. These colossal stellar beings captivate us with their immense size and radiance. Stars find their place on the main sequence depending on both mass and age, with mass determining when they will eventually depart from this stage of stellar evolution. The H-R diagram stands as an invaluable tool for astronomers seeking to unravel the mysteries of our universe's past and future. Its profound insights into stellar evolution have propelled humanity's understanding of these celestial wonders to new heights.
