Description
Infrared light curves of type Ia supernovae have been shown to provide an interesting pathway to extragalactic distances and a physical understanding of the explosions. The double peak provides interesting characteristics. The peak phases of the infrared relative to optical light curves gives an indication of the radiation physics and hints on why type Ia supernovae might be better standard candles than in the optical. The second peak holds information on the power source and the total mass in the explosion and also selects peculiar explosions.
