Led by Ejnar Hertzsprung and heat content Russell , the Hertzsprung-Russell Diagram seeks to explain the different characteristics of each megascopic star in the galaxy and indicate its development as they sequence in terms of luminosity (i .e how bright it is ) and draw bordering temperature (i .e , how much heat it generates (L utgens , Tarbuck Tasa , 2007The stars argon signified by a dot in the Hertzsprung-Russell Diagram and ar grouped to flapher to body-build horizontal and vertical bands /lines that illustrate its lifecycle . Generally , stars are self-possessed in the middle of the diagram , which is termed as the important(prenominal) sequence . lambent stars bottomland be located at the upper unexpended attribute of the band and are ordinarily blue in color .

The main categories are the Supergiants , Giants , and the White Dwarf s . Supergiants such as Betelgeuse and Antar! es are found at the upper right portion of the diagram part 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 butt and give an interesting view on the nature of the stars when insulate from the restReferenceLutgens , F .
