Finding the First Cosmic Explosions. IV. 90 - 140 M Pair-Instability Supernovae
Joseph Smidt, Daniel J. Whalen, E. Chatzopoulos +4
Population III stars that die as pair-instability supernovae are usually thought to fall in the mass range of 140 - 260 M. But several lines of work have now shown that r…
Supernovae at the cosmic dawn
Ke-Jung Chen
Modern cosmological simulations predict that the first generation of stars formed with a mass scale around 100 solar masses about 300-400 million years after the Big Bang. When the…
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…
Cosmological Impact of Population III Binaries
Ke-Jung Chen, Volker Bromm, Alexander Heger +2
We present the results of the stellar feedback from Pop III binaries by employing improved, more realistic Pop III evolutionary stellar models. To facilitate a meaningful compariso…
Very Massive Stars in the Local Universe
Jorick S. Vink
Recent studies suggest the existence of very massive stars (VMS) up to 300 solar masses in the local Universe. As this finding may represent a paradigm shift for the canonical stel…
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…
