Production Uncertainties of p-Nuclei in the -Process in Massive Stars Using a Monte Carlo Approach
T. Rauscher, N. Nishimura, R. Hirschi +3
Proton-rich nuclei, the so-called p-nuclei, are made in photodisintegration processes in outer shells of massive stars in the course of the final supernova explosion. Nuclear uncer…
Fast evolving pair-instability supernova models: evolution, explosion, light curves
Alexandra Kozyreva, Matthew Gilmer, Raphael Hirschi +11
With an increasing number of superluminous supernovae (SLSNe) discovered the question of their origin remains open and causes heated debates in the supernova community. Currently,…
Dependence of X-Ray Burst Models on Nuclear Reaction Rates
R. H. Cyburt, A. M. Amthor, A. Heger +5
X-ray bursts are thermonuclear flashes on the surface of accreting neutron stars and reliable burst models are needed to interpret observations in terms of properties of the neutro…
Uncertainties in the production of nuclei in massive stars obtained from Monte Carlo variations
T. Rauscher, N. Nishimura, R. Hirschi +3
Nuclear uncertainties in the production of nuclei in massive stars have been quantified in a Monte Carlo procedure. Bespoke temperature-dependent uncertainties were assigned to…
Low-energy Population III supernovae and the origin of extremely metal-poor stars
Ke-Jung Chen, Alexander Heger, Daniel J. Whalen +3
Some ancient, dim, metal-poor stars may have formed in the ashes of the first supernovae (SNe). If their chemical abundances can be reconciled with the elemental yields of specific…
