We present late-time (∼240–260 days after peak brightness) optical photometry and nebular (+236 and +264 days) spectroscopy of SN 2018oh, the brightest supernova (SN) Ia observed by the Kepler telescope. The Kepler/K2 30 minute cadence observations started days before explosion and continued past peak brightness. For several days after explosion, SN 2018oh had blue “excess” flux in addition to a normal SN rise. The flux excess can be explained by the interaction between the SN and a...[Show more]
