In the field of nuclear astrophysics, it pays to be creative. While direct measurements of astrophysically important reaction cross sections are still the ideal method for studying nucleosynthesis, often such direct measurements are not feasible with existing beam intensities and detection systems. Instead, key astrophysical levels can be populated through transfer reactions or beta decay, and...

Extending the limits of cross-section measurements to lower energies is a constant drive for Nuclear Astrophysics. Many unique approaches have been developed to overcome or navigate around the exponentially decreasing reaction probability at low energy extremes. As current laboratory experiments fight to approach this stellar burning window, the rapid reaction decrease drives the need for...

I report on the spatial distributions of carbonicity, [C/Fe], and
metallicity, [Fe/H], of the halo system of the Milky Way, based on
medium-resolution spectroscopy of ~58,000 stars in the Southern
Hemisphere from the AAOmega Evolution of Galactic Structure (AEGIS)
survey. I also consider the populations of carbon-enhanced metal-poor
(CEMP) stars present in the AEGIS sample and confirm...

TRIUMF’s Ion Trap for Atomic and Nuclear science (TITAN) at TRIUMF performs mass measurements of unstable nuclei relevant to nucleosynthesis to both high precision and accuracy. The nuclear binding energies given by these masses are important parameters in determining the path of the r-process and the final abundances of the chemical elements. Penning trap mass spectrometry has been used at...

Certain astrophysical environments such as thermonuclear outbursts on accreting neutron stars (Type-I X-ray bursts) are hot enough to allow for breakout from the Hot CNO hydrogen burning cycles to the rapid proton capture (rp) process. An important breakout reaction sequence is 15O(α,γ)19Ne(p,γ)20Na and the 19Ne(p,γ)20Na reaction rate is expected to be dominated by a single resonance at 457...
