Using Light Curves to Classify Supernovae

Observe the light curves for two supernovae.

7. Which graph shows a supernova that increases to a peak brightness and then dims continuously over a period of months?

8. Which graph shows a supernova that increases until reaching a peak brightness, then its brightness level drops slightly, and its brightness remains approximately the same for several months?

9. Which graph shows a Type IIp supernova?
