Early Spectroscopy and Dense Circumstellar Medium Interaction in SN 2023ixf

By K. Azalee Bostroem and others
We present the optical spectroscopic evolution of SN~2023ixf seen in sub-night cadence spectra from 1.18 to 14 days after explosion. We identify high-ionization emission features, signatures of interaction with material surrounding the progenitor star, that fade over the first 7 days, with rapid evolution between spectra observed within the same...
