From Supernova to Supernova Remnant: Comparison of Thermonuclear Explosion Models

Progress in the three-dimensional modeling of supernovae (SNe) prompts us to revisit supernova remnant (SNR) phase. We continue our study imprint a thermonuclear explosion on SNR it produces, which we started with delayed detonation model Chandrasekhar-mass white dwarf. Here compare two different types models, each variants: models (N100ddt, N5ddt) and pure deflagration (N100def, N5def), where N number parameterizes ignition. The output SN simulation is used as input an carried until 500 yr after explosion. While all become more spherical over time overall display theoretical structure expected for young SNR, clear differences are visible among depending geometry ignition presence or not fronts. Compared N100 N5 have strong dipole component produce asymmetric remnants. N5def produces regular-looking, but offset remnant, while N5ddt two-sided remnant. Pure exhibit specific traits: central overdensity, because incomplete explosion, network seam lines across surface, boundaries between burning cells. Signatures from dominate morphology up 100–300 model, still measurable at yr, may provide way testing models.
