Pair-Instability Supernovae of Non-Zero Metallicity Stars
Ke-Jung Chen, Alexander Heger, Stan Woosley +2
Observational evidence suggests that some very massive stars in the local Universe may die as pair-instability supernovae. We present 2D simulations of the pair-instability superno…
Pair Instability Supernovae of Very Massive Population III Stars
Ke-Jung Chen, Alexander Heger, Stan Woosley +2
Numerical studies of primordial star formation suggest that the first stars in the universe may have been very massive. Stellar models indicate that non-rotating Population III sta…
General Relativistic Instability Supernova of a Supermassive Population III Star
Ke-Jung Chen, Alexander Heger, Stan Woosley +3
The formation of supermassive Population III stars with masses 10,000 Msun in primeval galaxies in strong UV backgrounds at 15 may be the most viable pathway to…
Two-Dimensional Simulations of Pulsational Pair-Instability Supernovae
Ke-Jung Chen, Stan Woosley, Alexander Heger +2
Massive stars that end their lives with helium cores in the range of 35 to 65 Msun are known to produce repeated thermonuclear outbursts due to a recurring pair-instability. In som…
