Light curves and Spectra

Light curves and Spectra. SN Light Curves. A SN shines for different reasons, and different types of SN may only show some of the various mechanisms Some SN classification is done on the basis of the Light curve properties

Supernovae continued

Supernovae continued. ?-rich Freezeout. Freezeout - nuclear reactions halted before coming to equilibrium or steady state configuration by temperature & density evolution ?-rich freezeout occurs in material shocked to NSE temperatures. Expansion causes density to drop below critical value
