Empirical Solar Abundance Scalings of Supernova Gamma-Process Isotopes
Analyzing the solar system abundances, we have found two empirical scaling laws concerning the pand s-nuclei with the same atomic number. These scalings are evidence that most probable origin of 27 p-nuclei is the supernova γ-process. We have calculated the abundance ratios by the γ-process nucleosynthesis based on core-collapse supernova explosion models under various astrophysical conditions....
متن کاملTi: Its effective decay rate in young supernova remnants, and its abundance in CasA
Radioactive isotopes such as Ti offer probably the most direct probe into nucleosynthesis environments in the interior of exploding stars, when the associated γ-ray activities in the explosion remnant are detected and translated back to the isotopic abundances at the time of the explosion. In this paper, we assert that the procedure may not necessarily be straightforward, at least in the case o...
متن کامل44Ti: its effective decay rate in young supernova remnants, and its abundance in Cassiopeia A
Radioactive isotopes such as 44Ti offer probably the most direct probe into nucleosynthesis environments in the interior of exploding stars, when the associated γ-ray activities in the explosion remnant are detected and translated back to the isotopic abundances at the time of the explosion. In this paper, we assert that the procedure may not necessarily be straightforward, at least in the case...
متن کاملSupernova Neutrinos
A nascent neutron star resulting from stellar collapse is a prodigious source of neutrinos of all flavors. While the most basic features of this neutrino emission can be estimated from simple considerations, the detailed simulation of the neutrinos’ decoupling from the hot neutron star is not yet computationally tractable in its full glory, being a time-dependent six-dimensional transport probl...
متن کاملSupernova 1987A
First, I summarize the main points that we have learned about the interior of SN1987A. Then, I describe in greater detail the rapidly developing impact of SN1987A with its inner circumstellar ring.
