The Late Time Optical Evolution of Twelve Core-Collapse Supernovae: Detection of Normal Stellar Winds

We analyze the late time evolution of 12 supernovae (SNe) occurring over the last {\sim}41 years, including nine Type IIP/L, two IIb, and one Ib/c, using UBVR optical data from the Large Binocular Telescope (LBT) and difference imaging. We see late time (5 to 42 years) emission from nine of... Show more
