The rates of certain nuclear reactions involving neutron-deficient nuclei are important in explosive astrophysical environments. Measurements using radioactive beams are improving our understanding of these reaction rates, but the relatively low intensity of the available beams requires some creative experimental approaches involving both direct and indirect techniques. We will present an...

Forty years of studying thermonuclear (type-I) bursts from accreting neutron stars have revealed a surprisingly rich spectrum of behaviour. A few sources which have been studied intensively offer confirmed examples of two of the three classes of ignition predicted theoretically, and these systems serve as crucial test-cases for numerical models. Some new classes of bursts have also emerged in...

The composition and phase separation of rp-ash on accreting neutron stars determine the thermal properties of the crust. These properties must be understood to interpret observations of crust cooling in X-ray bursts. In this work, we report on recent large scale molecular dynamics simulations of the outer crust. Using the compositions calculated by Mckinven et al. 2016, we study the structure...

Observing the surface of neutron stars provides the crucial information about their radius that is necessary to understand their interior composition, and therefore to place constraints on the equation of state of matter at extreme densities. While a few independent methods permit measurements of the neutron star radius, the existence of potential systematic uncertainties have been pointed...

The 34Ar(α,p)37K reaction is important in Type I X-ray bursts
(XRBs), where nucleosynthesis proceeds through the α,p and
rp processes up to A<100. Waiting-point nuclei in XRBs (e.g.
34Ar) are in (p,γ)-(γ,p) equilibrium and may stall the burst, but
the (α,p) reaction may provide a detour. We performed 37K+p
elastic scattering to study the compound nucleus 38Ca at the
ReA3 facility at the...
