Kavli Affiliate: Lile Wang | First 5 Authors: Xiaoyu Zhang, Xiaoyu Zhang, , , | Summary: We present direct numerical simulations demonstrating deflagration-to-detonation transition (DDT) driven by oxygen flames in Type Ia supernova progenitors. Using the Castro hydrodynamics code coupled with the “aprox13” 13-isotope nuclear network, we simulate combustion in isolated fuel regions where oxygen […]
