Neutron capture on Sn during r-process freeze-out
نویسندگان
چکیده
We examine the role of neutron capture on Sn during r-process freezeout in the neutrino-driven wind environment of the core-collapse supernova. We find that the global r-process abundance pattern is sensitive to the magnitude of the neutron capture cross section of Sn. The changes to the abundance pattern include not only a relative decrease in the abundance of Sn and an increase in the abundance of Sn, but also a shift in the distribution of material in the rare earth and third peak regions. ar X iv :0 80 6. 38 95 v1 [ nu cl -t h] 2 4 Ju n 20 08 Neutron capture on Sn during r-process freeze-out 2

NEUTRINO-INDUCED NEUTRON SPALLATION AND THE SITE OF THE r-PROCESS
All of the actinides and roughly half the natural abundance of elements with mass number A > 70 come from the rapid neutron capture process, or the r-process. If the r-process, as suggested by many, occurs deep in a supernova, then it is under the influence of an intense neutrino flux. Here we discuss the effects of both chargedcurrent and neutral-current neutrino interactions on the r-process....
متن کاملWeak Charge-Changing Flow in Expanding r-Process Environments
We assess the prospects for attaining steady nuclear flow equilibrium in expanding r-process environments where beta decay and/or neutrino capture determine the nuclear charge-changing rates. For very rapid expansions, we find that weak steady flow equilibrium normally cannot be attained. However, even when neutron capture processes freeze out in such nonequilibrium conditions, abundance ratios...
متن کاملThe Role of Fission in Neutron Star Mergers and its Impact on the r-Process Peaks
Comparing observational abundance features with nucleosynthesis predictions of stellar evolution or explosion simulations can scrutinize two aspects: (a) the conditions in the astrophysical production site and (b) the quality of the nuclear physics input utilized. We test the abundance features of r-process nucleosynthesis calculations for the dynamical ejecta of neutron star merger simulations...
متن کاملFurther Evidence for the Bimodal Distribution of Neutron-star Masses
We use a collection of 14 well-measured neutron-star masses to strengthen the case that a substantial fraction of these neutron stars were formed via electron-capture (e-capture) supernovae (SNe) as opposed to Fe corecollapse SNe. The e-capture SNe are characterized by lower resultant gravitational masses and smaller natal kicks, leading to lower orbital eccentricities when the e-capture SN has...
متن کاملβ-Decay Half-Lives of 110 Neutron-Rich Nuclei across the N=82 Shell Gap: Implications for the Mechanism and Universality of the Astrophysical r Process.
The β-decay half-lives of 110 neutron-rich isotopes of the elements from _{37}Rb to _{50}Sn were measured at the Radioactive Isotope Beam Factory. The 40 new half-lives follow robust systematics and highlight the persistence of shell effects. The new data have direct implications for r-process calculations and reinforce the notion that the second (A≈130) and the rare-earth-element (A≈160) abund...
