We compare a suite of 3D explosion calculations and stellar modelsincorporating advanced physics with observational constraints on the progenitorof Cassiopeia A. We consider binary and single stars from 16 to 40 solar masseswith a range of explosion energies and geometries. The parameter space allowedby observations of nitrogen rich high velocity ejecta, ejecta mass, compactremnant mass, and 44Ti and 56Ni abundances individually and as an ensemble isconsidered. A progenitor of 15-25 solar masses which loses its hydrogenenvelope to a binary interaction and undergoes an energetic explosion can matchall the observational constraints.Comment: 31 pages, 4 figures, accepted for publication to the Astrophysical Journa
