Evolution of the GCD200 model for six different instances of time. The deflagration level set is shown in red and the detonation level set in blue. Since the deflagration ashes almost completely surround the detonation, we have rendered the deflagration level set semi-transparent to allow visualizing the enclosed detonation front. The spatial scales in the plots are 1.23 × 10¹⁰ cm, 1.25 × 10¹⁰ cm, 1.33 × 10¹⁰ cm, 1.47 × 10¹⁰ cm, 2.46 × 10¹⁰ cm, and 1.59 × 10¹² cm for panels a) to f), respectively.
