Long, Cold, Early r Process? Neutrino-Induced Nucleosynthesis in He Shells Revisited

Journal Article Banerjee, Projjwal ; Yongzhong, Qian ; Haxton, W C - Physical Review Letters

We revisit a {nu}-driven r-process mechanism in the He shell of a core-collapse supernova, finding that it could succeed in early stars of metallicity Z < or approx. 10{sup -3}Z{sub {center_dot}}, at relatively low temperatures and neutron densities, producing A{approx}130 and 195 abundance peaks over {approx}10-20 s. The mechanism is sensitive to the {nu} emission model and to {nu} oscillations. We discuss the implications of an r process that could alter interpretations of abundance data from metal-poor stars, and point out the need for further calculations that include effects of the supernova shock.

$r$ -process nucleosynthesis from matter ejected in binary neutron star mergers [On $r$ -process nucleosynthesis from matter ejected in binary neutron star mergers]

Journal Article Bovard, Luke ; Martin, Dirk ; Guercilena, Federico ; ... - Physical Review D

Here, when binary systems of neutron stars merge, a very small fraction of their rest mass is ejected, either dynamically or secularly. This material is neutron-rich and its nucleosynthesis provides the astrophysical site for the production of heavy elements in the Universe, together with a kilonova signal confirming neutron-star mergers as the origin of short gamma-ray bursts. We perform full general-relativistic simulations of binary neutron-star mergers employing three different nuclear-physics equations of state (EOSs), considering both equal- and unequal-mass configurations, and adopting a leakage scheme to account for neutrino radiative losses. Using a combination of techniques, we carry out anmore »« less

$β$ -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

Journal Article Lorusso, G. ; Nishimura, S. ; Xu, Z. Y. ; ... - Physical Review Letters

The β -decay half-lives of 110 neutron-rich isotopes of the elements from Rb 37 to Sn 50 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 ) abundance peaks may result from the freeze-out of an (n,γ)⇌(γ,n) equilibrium. In such an equilibrium, the new half-lives are important factors determining the abundance of rare-earth elements, and allow for a more reliable discussion of the rmore »« less
