Subject: The Biggest Explosions of the Universe: Simulations of Thermonuclear Supernovae of Very Massive Stars

Current models of the formation of the first stars in the universe suggest that these stars were very massive, having a typical mass scale of hundreds of solar masses. Such stars would explode as pair instability supernovae (PSNe). We present the results from multidimensional numerical studies of PSNe with a new radiation-hydrodynamics code, CASTRO. We simulate the fluid instabilities that occur in multiple spatial dimensions and discuss how the resulting mixing affects the explosion and nucleosynthesis of these supernovae.
