Three-Dimensional Hydrodynamical Full-Star Simulations of Turbulence-Driven Deflagration-to-Detonation Transition in Thermonuclear Supernovae

Recent progress has been made in establishing an experimentally-validated turbulence-driven deflagration-to-detonation transition (tDDT) mechanism. In this work, we present 3D hydrodynamical simulations of thermonuclear Type Ia supernovae (SNe Ia) incorporating the tDDT mechanism for the first time. We will discuss the implications of these findings for the turbulent initiation of detonations in unconfined media. These results enhance the predictive capability of the SNe Ia models and provide insights into the role of turbulence in driving DDT.
