Abstract
We present results from the first high‐resolution, high signal‐to‐noise ratio spectrum of SN 2002ic. The resolved Hα line has a P Cygni‐type profile, clearly demonstrating the presence of a dense, slow‐moving (∼100 km s−1) outflow. We have additionally found a huge near‐infrared excess, hitherto unseen in Type Ia supernovae. We argue that...More
