The Uncertainties in the 22Ne + alpha-capture Reaction Rates and the Production of the Heavy Magnesium Isotopes in Asymptotic Giant Branch Stars of Intermediate Mass
A. Karakas, M. Lugaro, M. Wiescher +2
We present new rates for the 22Ne(alpha, n)25Mg and 22Ne(alpha,gamma)26Mg reactions, with uncertainties that have been considerably reduced compared to previous estimates, and we s…
The impact of the 18F(a,p)21Ne reaction on fluorine production in AGB stars
Amanda I. Karakas, Hye Young Lee, Maria Lugaro +2
The recent experimental evaluation of the 18F(a,p)21Ne reaction rate, when considering its associated uncertainties, presented significant differences compared to the theoretical H…
Sensitivity of p-Process Nucleosynthesis to Nuclear Reaction Rates in a 25 Solar Mass Supernova Model
W. Rapp, J. Goerres, M. Wiescher +2
The astrophysical p process, which is responsible for the origin of the proton rich stable nuclei heavier than iron, was investigated using a full nuclear reaction network for a ty…
Reaction rates for Neutron Capture Reactions to C-, N- and O-isotopes to the neutron rich side of stability
H. Herndl, R. Hofinger, J. Jank +5
The reaction rates of neutron capture reactions on light nuclei are important for reliably simulating nucleosynthesis in a variety of stellar scenarios. Neutron capture reaction ra…
The neutron long counter NERO for studies of beta-delayed neutron emission in the r-process
J. Pereira, P. Hosmer, G. Lorusso +23
The neutron long counter NERO was built at the National Superconducting Cyclotron Laboratory (NSCL), Michigan State University, for measuring beta-delayed neutron-emission probabil…
AGB yields and Galactic Chemical Evolution: last updated
S. Bisterzo, C. Travaglio, M. Wiescher +7
We study the s-process abundances at the epoch of the Solar-system formation as the outcome of nucleosynthesis occurring in AGB stars of various masses and metallicities. The calcu…
