Late Phase Light Curves of SN 2005hk
Abstract
Understanding the light curves of Type Ia Supernovae (SNe Ia) is essential to their use as standard candles in cosmological studies. Recent observations of SNe Ia have shown brighter than expected NIR emission at very late phases resulting in brighter than expected bolometric luminosity at that epoch. Also, some observations showed that the optical bands at very late phases were brighter than expected relative to the 200-330 day slope. Further study of these objects in both the optical and NIR bands is needed to better understand their behavior. We present the optical and NIR late phase light curves of the peculiar SN 2005hk as a tool to probe these questions.
