Lightning Talk: In-Situ Temperature Profiling for Determining Detonation in White Dwarf Environments
DescriptionThe temperature profile in white dwarf (WD) mergers plays a critical role in determining where and how detonations occur in stellar simulations. Existing methods, which primarily focus on maximum and ambient temperatures, often lack the precision needed for comprehensive detonation analysis. To address this, we developed a novel temperature profiling method that enhances accuracy by incorporating additional data, such as the size and average distance of hotspots on the star’s surface. This approach enables a more detailed understanding of detonation conditions. By implementing real-time, in-situ temperature profiling, we minimize the computational overhead typically caused by input/output (I/O) operations and data modeling, with the overhead ranging from 0.11% to 2.28% of total simulation time. In testing with Castro's wdmerger simulation, our method produced results with a significant speed-up of 8.55x in execution time of temperature profiling over Seitenzahl's method while maintaining the same level of accuracy among multiple WD detonation cases.
