We use high-resolution cosmological simulations to compare the effect ofbursty star formation histories on dwarf galaxy structure for two differentsubgrid supernovae (SNe) feedback models in dwarf galaxies with stellar massesfrom $5000 <$ M$_*$/M$_\odot$ $< 10^{9}$. Our simulations are run using twodistinct supernova feedback models: superbubble and blastwave. We show thatboth models are capable of producing galaxies that are cored and reproduceobserved scaling relations for metallicity, luminosity, mass, and size. We showthat continuous bursty star formation and the resulting stellar feedback areable to sustain dark matter cores in the higher dwarf galaxy mass regime, whilethe majority of ultra-faint and classical dwarfs retain cuspy central darkmatter density profiles. We find that both subgrid SN models are able to createbursty star formation histories. We find that effective core formation peaks atM$_*$/M$_\odot$ $\simeq 5 \times 10^{-3}$ for both feedback models. Galaxiessimulated with superbubble feedback peak at lower mean burstiness valuesrelative to blastwave feedback, indicating that core formation in thesuperbubble sample may be less motivated by the burstiness of star formation.
