Interactive Stellar Class Activity

Notice that it is a very different graph than you are probably used to. It has a label on each side and top and bottom.

For now, you will be plotting the star's Luminosity along the left side against the star's Temperature along the top. Find where the two meet and then drag one of the little generic black stars there.
