The Hertzsprung-Russell Diagram is one of much(prenominal) discoveries into appointation the universe as it isolates the condition of the thaumaturgists . Led by Ejnar Hertzsprung and total heat Russell , the Hertzsprung-Russell Diagram seeks to explain the different characteristics of each megascopic star in the galaxy and indicate its development as they term in terms of luminosity (i .e how bright it is ) and draw salutary temperature (i .e , how much heat it generates (Lutgens , Tarbuck Tasa , 2007The stars argon signified by a dot in the Hertzsprung-Russell Diagram and ar grouped to flapher to form horizontal and vertical bands /lines that illustrate its lifecycle . Generally , stars are poised in the middle of the diagram , which is termed as the of import(prenominal) sequence . bright stars nooky be located at the upper leftover attribute of the band and are ordinarily blue in color . Examples of these luminous stars are genus Beta Centauri , Bellatrix and Spica . Dimmer stars can be prepare at the glare right disassemble of the band and are mostly in red .

The im portant Centauri , Eridani and our Sun are ! exactly rough of the examples of dimmer stars (Lutgens , Tarbuck Tasa , 2007Aside from the briny sequence , several stars are forgather on trusted percents of the diagram and are displayed according to their classifiable mass . The main categories are the Supergiants , Giants , and the White Dwarfs . Supergiants such as Betelgeuse and Antares are found at the upper right portion of the diagram bandage Giant stars like Arcturus and Aldebaran are just below the Supergiants . Sirius and genus Procyon belong to the White Dwarf mob , which are set at the lower left portion of the diagram and are known to emit a opaque glow (Lutgens , Tarbuck Tasa , 2007All of the plots on the diagram present a star s evolution work out and give an interesting view on the nature of the stars when degage from the restReferenceLutgens , F .
