Name _________________________________________ Block _________ The H-R Diagram and Stars Worksheet 1. Below is the Hertzsprung-Russell (H-R) Diagram. This diagram plots _________________ vs. __________________. 2. Use your book to add the following information to the H-R diagram. a. Page 622 – Add the Spectral Class below the temperatures. b. Page 626 – Use colored pencils to add and label the band that represents Main Sequence stars. c. Page 626 – Use colored pencils to label the following areas: Blue Giants, Red Super Giants, Red Giants, Red Dwarfs, White Dwarfs d. Page 626 - Label the following stars: Spica, Vega, Sun, Proxima Centauri, Rigel, Betelgeuse, Aldebaran. 3. Describe general characteristics about each of the following star types: p.626 a. Main sequence – b. Giants – c. Supergiants – d. White dwarfs – 4. Use colored pencils to sketch the life cycle of a star, starting with nebula and ending with white dwarf, black hole and neutron star (show all possible paths to star death). p. 628 5. Describe each of the following stages: p. 628 a. Protostar b. Planetary nebula c. Supernova d. Neutron star e. Pulsar f. Black hole Groups of Stars – Galaxies 6. Describe the shape of each type of galaxy. p.631 a. Spiral b. Elliptical c. Irregular 7. What type of galaxy do we live in? _______________________ What is its name? _______________________ p. 632
