Extended Data Fig. 5: Spectral evolution of SN 2022jli before and during the fast decline phase of the light curve.
From: A 12.4-day periodicity in a close binary system after a supernova

The top left panel shows the bolometric light curve, and the top right panel shows the zoom-in view of the fast decline phase of the light curve. The second panel shows the six epochs of spectra as indicated in the top right panel. The bottom three panels show the zoom-in view of the spectra within different wavelength ranges. All spectra in the bottom three panels have been scaled to have the same integrated luminosity between 3800 to 9000 Å as the BINOSPEC spectrum taken on 12 January 2022.
