Journal ArticleDOI
Reaction Rate Uncertainties and the Production of 19F in Asymptotic Giant Branch Stars
Maria Lugaro,Claudio Ugalde,Amanda I. Karakas,Joachim Görres,Michael Wiescher,John C. Lattanzio,Robert C Cannon +6 more
TL;DR: In this article, a detailed analysis of the reaction rates involved in the production of 19F and the effects of their uncertainties were performed for a large set of models with different masses and metallicity.
Journal ArticleDOI
Reaction Rates Uncertainties and the Production of F19 in AGB Stars
Maria Lugaro,Claudio Ugalde,Amanda I. Karakas,Joachim Görres,Michael Wiescher,John C. Lattanzio,Robert C Cannon +6 more
TL;DR: In this paper, a detailed analysis of the reaction rates involved in the production of 19F stellar yields and the effects of their uncertainties are presented, and the major uncertainties are associated with the 14C(alpha,gamma)18O and the 19F(α,p)22Ne reaction rates.
Journal ArticleDOI
AZURE: An R-matrix code for nuclear astrophysics
R. E. Azuma,R. E. Azuma,Ethan Uberseder,Edward Simpson,Edward Simpson,Carl R. Brune,H. Costantini,R.J. de Boer,Joachim Görres,Michael Heil,P. J. LeBlanc,Claudio Ugalde,Michael Wiescher +12 more
TL;DR: In this article, the authors describe a multilevel, multichannel R-matrix code, AZURE, for applications in nuclear astrophysics, which allows simultaneous analysis and extrapolation of low-energy particle scattering, capture, and reaction cross sections of relevance to stellar hydrogen, helium, and carbon burning.
Journal ArticleDOI
Charged-Particle Thermonuclear Reaction Rates: I. Monte Carlo Method and Statistical Distributions
Richard Longland,Richard Longland,Christian Iliadis,Christian Iliadis,Arthur E Champagne,Arthur E Champagne,Joe Newton,Joe Newton,Claudio Ugalde,Claudio Ugalde,Alain Coc,Alain Coc,Ryan P. Fitzgerald +12 more
TL;DR: In this article, a method based on Monte Carlo techniques is presented for evaluating thermonuclear reaction rates, which results in a median (Monte Carlo) rate which agrees under certain conditions with the commonly reported recommended "classical" rate.
Journal ArticleDOI
The 13 C ( α , n ) reaction and its role as a neutron source for the s process
Matthias Heil,R. Detwiler,R. E. Azuma,R. E. Azuma,Aaron Couture,J. Daly,Joachim Görres,F. Käppeler,Rene Reifarth,P. Tischhauser,Claudio Ugalde,Michael Wiescher +11 more
TL;DR: In this article, the authors used the multichannel code SAMMY to constrain possible contributions from background resonances for a reliable extrapolation with the multiichannel $R$-matrix codeSAMMY.
