Very Late-Time JWST and Keck Spectra of the Oxygen-Rich Supernova 1995N

Geoffrey C. Clayton, R. Wesson, Ori D. Fox +43

We present new {\it JWST}/MIRI MRS and Keck spectra of SN 1995N obtained in 2022--2023, more than 10,000 days after the supernova (SN) explosion. These spectra are among the latest…
