Elements in a CCSN (s19.8-fid, clipped)

Distribution of elements in the ejecta of an aspherical core-collapse supernova explosion is revealed through a 3D representation of isosurfaces of mass fractions, showcasing the presence of 56Ni in red, 28Si in green, 16O in blue, and 4He in light blue just before shock breakout. Approximately 82,000 seconds after the explosion, these elements are depicted in a 3D view with lighter and darker colors indicating 10% and 70% of their maximum values respectively. To gain insight into the inner structure, certain regions have been clipped from this model which was developed within an extended study detailed in the paper "Matter Mixing in Aspherical Core-collapse Supernovae: Three-dimensional Simulations with Single Star and Binary Merger Progenitor Models for SN 1987A". This research by Masaomi Ono, Shigehiro Nagataki, Gilles Ferrand, Koh Takahashi, Hideyuki Umeda, Takashi Yoshida, Salvatore Orlando, and Marco Miceli was published in The Astrophysical Journal (2020) under the identification number 111.
