Thinking about the Concepts: 29, 30, 33
29 For size and chemical composition you should know the stars distance.
You do not need to know the stars distance for mass, temperature, color and spectral type
30 From the location, the luminosity can be read from the y-axis. Stellar mass increases
smoothly from the lower right to the main sequence.
33 Betelgeuse has a cooler temperature, brighter luminosity and the size is smaller while the
star Rigel has a hotter temperature, dimmer luminosity and the size is larger.
Applying the Concepts: 47, 48, 49, 51
47 50 / 2.35 = 21.27
