Understanding globular cluster abundances through nuclear reactions
P Adsley, M Williams, D S Harrouz +24
Globular clusters contain multiple stellar populations, with some previous generation of stars polluting the current stars with heavier elements. Understanding the history of globu…
First inverse kinematics measurement of resonances in Be()C relevant to neutrino-driven wind nucleosynthesis using DRAGON
A. Psaltis, A. A. Chen, R. Longland +18
A possible mechanism to explain the origin of the light -nuclei in the Galaxy is the nucleosynthesis in the proton-rich neutrino-driven wind ejecta of core-collapse supernovae v…
Direct measurement of resonances in Be()C relevant to -process nucleosynthesis
A. Psaltis, A. A. Chen, R. Longland +18
We have performed the first direct measurement of two resonances of the Be()C reaction with unknown strengths using an intense radioactive Be beam and the DRAGO…
New measurement of the keV resonance in the Fp,γ^{20}$Ne reaction
M. Williams, P. Adsley, B. Davids +6
At temperatures below 0.1 GK the FNe reaction is the only breakout path out of the CNO cycle. Experimental studies of this reaction are challenging from a techni…
Constraints on key O()Ne resonances and impact on the weak s-process
M. Williams, A. M. Laird, A. Choplin +7
The efficiency of the slow neutron-capture process in massive stars is strongly influenced by neutron-capture reactions on light elements. At low metallicity, O is an import…
Beyond the acceptance limit of DRAGON: the case of the reaction
A. Psaltis, A. A. Chen, D. S. Connolly +13
Radiative capture reactions play a pivotal role for our understanding of the origin of the elements in the cosmos. Recoil separators provide an effective way to study these reactio…

M. Williams, A. Lennarz, A. M. Laird +17
The abundances of sodium and oxygen are observed to be anti-correlated in all well-studied globular clusters. Asymptotic giant branch (AGB) stars undergoing hot bottom burning (HBB…
A direct measurement of the 17O(a,g)21Ne reaction in inverse kinematics and its impact on heavy element production
M. P. Taggart, C. Akers, A. M. Laird +33
During the slow neutron capture process in massive stars, reactions on light elements can both produce and absorb neutrons thereby influencing the final heavy element abundances. A…

According to sensitivity studies, the reaction has a significant influence on , , and p…
Design and commissioning of a timestamp-based data acquisition system for the DRAGON recoil mass separator
G. Christian, C. Akers, D. Connolly +4
The DRAGON recoil mass separator at TRIUMF exists to study radiative proton and alpha capture reactions, which are important in a variety of astrophysical scenarios. DRAGON experim…
Constraining nova observables: direct measurements of resonance strengths in 33S(p,γ)34Cl
