Production of 26Al, 44Ti and 60Fe in Supernovae-sensitivity to the helium burning rates
Clarisse Tur, Alexander Heger, Sam M. Austin
We have studied the sensitivity of supernova production of the gamma emitting nuclei 26Al, 44Ti and 60Fe to variations of the rates of the triple alpha and 12C(alpha, gamma) reacti…
Two Dimensional Simulations of Pair-Instability Supernovae
Ke-Jung Chen, Alexander Heger, Ann S. Almgren
We present preliminary results from two dimensional numerical studies of pair instability supernova (PSN). We study nuclear burning, hydrodynamic instabilities and explosion of ver…
Multi-Dimensional Simulations of Pair-Instability Supernovae
Ke-Jung Chen, Alexander Heger, Ann Almgren
We present preliminary results from multidimensional numerical studies of pair instability supernova (PSN), studying the fluid instabilities that occur in multiple spatial dimensio…
