Summary SN Ia: Binary white dwarf mergers: shear and turbulence Unequal masses: no evidence for prompt ignition Equal masses: no evidence for prompt ignition Expect central ignitions with fast rotating envelopes Likely different from typical models with smooth rotation Perhaps similar to Yoon & Langer structure Shear/KHI HED studied and analyzed; HED turbulence experiment concept developed SN Ia: In-situ generated magnetic fields for Type Ia deflagrations Identified as a possible new physics in HED RTI experiments For supernova conditions, reduced turbulence near the flame Smoother flame surface Lower effective flame speed, large scales more important Flame remains RT-driven and mushroom-like in appearance SN II: Core-collapse Exploring possible SASI experimental designs SASI asymmetries may suffice to explain SN 1987A and alikes Crab-like spongy morphologies for young ccSNR Diverging SNRT to be executed on NIF!
