Two representative ejecta models whose bolometric luminosities fit the light curve of AT2025abao. (a)–(i) The time-dependent density, ejecta radial velocity, temperature, Mach number, Er-to-eg ratio, pr-to-pg ratio, cumulative gas and radiation energies, mass-injection rate through the inner boundary, and cumulative injected mass. The two ejecta have very different initial speeds but similar cumulative masses and energies.
