Top: evolution of the various energy components in the RE1B3p5 simulation. We show Ekin +th, which sums the kinetic and thermal (i.e., gas) energy; Erad,trapped, which is the trapped radiation energy; Edep,pm, which is the energy deposited by the magnetar; Erad,losses, which is the radiative energy streaming out through the outer grid boundary; and ΔE ≡ Ekin+th + Erad,trapped + Erad,losses − Edep,pm, which tracks conservation of energy. The start of the simulation is 1.15 d in all simulations — any magnetar energy deposited prior to that is ignored. Middle and bottom: evolution of the radiative losses (middle) and of the fraction of the magnetar deposited energy that escapes as radiation as a function of time (bottom) for the magnetar-powered SN models based on the RSG progenitor. Additional illustrations are provided in Appendix A.
