to represent both symbols
Compare your graph with the H-R diagram at the top of this assignment. Label each type of star on your graph. (example: label the white dwarf section, the main sequence section, etc.)
Our Sun has a temperature of 5800 K (which is 6073Celsius) and an absolute magnitude of +4.7. Use a
symbol to plot the location of the Sun on your diagram. Use the two tables to plot the points on the graph attached as a PDF
