The Hertzsprung-Russell Diagram is one of much(prenominal) discoveries into be the universe as it isolates the condition of the friends . Led by Ejnar Hertzsprung and henry Russell , the Hertzsprung-Russell Diagram seeks to explain the different characteristics of each panoptic star in the galaxy and indicate its development as they come along in terms of luminosity (i .e how b counterbalance it is ) and fold up temperature (i .e , how much heat it generates ( Lutgens , Tarbuck Tasa , 2007The stars be signified by a dot in the Hertzsprung-Russell Diagram and atomic number 18 grouped to outwither to establish horizontal and vertical bands /lines that illustrate its lifecycle . Generally , stars be equanimous in the middle of the draw , which is termed as the primary(prenominal) sequence . luminous stars rump be located at the upper leftfield tract of the band and are unremarkably blue in color .

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 while Giant stars like Arcturus and Aldebaran are just on a lower floor the Supergiants . Sirius and Procyon belong to the White Dwarf kin , which are situated at the lower left portion of the diagram and are known to emit a opaque insolence (Lutgens , Tarbuck Tasa , 2007All of the plots on the diagram present a star s ontogenesis process and give an interesting view on the nature of the stars when isolated from the restReferenceLutgens , F .
