Rotation exerts muted effects on 3D explosion dynamics of 9-solar-mass progenitors
Rotation alone produces only marginal changes to energy, asymmetry, and yields in early-exploding low-mass supernovae. The work isolates spin as a variable but omits magnetic fields, limiting applicability to the broader progenitor population. Stronger evidence requires magnetized, multi-mass 3D grids now feasible on exascale machines.
Future runs must incorporate realistic progenitor magnetic fields and explore a mass grid above 12 M⊙ to test whether rotation becomes dynamically important only when explosion timescales exceed 200 ms. Multi-messenger predictions for gravitational-wave strain and neutrino flavor ratios will remain robust only if these extensions confirm the present weak dependence.
Burrows: Inclusion of progenitor magnetic fields will increase explosion asymmetry by >15 % for the 9-M⊙ model within 18 months of new runs.
