Use the data in table 12.6 below to plot an H-R diagram. Which star is a red giant? Which is a white dwarf? Note: Plotting will be much easier if you plot the logarithm of the luminosity; that is, express it in powers of 10 and use the power. For example, if the luminosity is 100, plot it as 2 for 102. Alternatively, use a pocket calculator as follows. Enter the luminosity in solar units and hit the "log" key. If the luminosity is 300,000, the answer you get should be 5.477. . . .  table 12.6
