Modeling the progenitors of low-mass post-accretion binaries

A. J. Dimoff, R. J. Stancliffe, C. J. Hansen +2

About half of the mass of all heavy elements with mass number A > 90 is formed through the slow neutron capture process (s-process), occurring in evolved asymptotic giant branch (A…

S-Process Nucleosynthesis in Chemically Peculiar Binaries

A. J. Dimoff, C. J. Hansen, R. J. Stancliffe +4

Around half of the heavy elements in the universe are formed through the slow neutron capture (s-) process, which takes place in thermally pulsing asymptotic giant branch (AGB) sta…

The chemical evolution of the solar neighbourhood for planet-hosting stars

Marco Pignatari, Thomas C. L. Trueman, Kate A. Womack +13

Theoretical physical-chemical models for the formation of planetary systems depend on data quality for the Sun's composition, that of stars in the solar neighbourhood, and of the e…

Type Ia Supernova Nucleosynthesis: Metallicity-Dependent Yields

James D Keegans, Marco Pignatari, Richard J Stancliffe +7

Type Ia supernova explosions (SNIa) are fundamental sources of elements for the chemical evolution of galaxies. They efficiently produce intermediate-mass (with Z between 11 and 20…

Isotopic ratios for C, N, Si, Al, and Ti in C-rich presolar grains from massive stars

Jordan Schofield, Marco Pignatari, Richard J Stancliffe +1

Certain types of silicon carbide (SiC) grains, e.g., SiC-X grains, and low density (LD) graphites are C-rich presolar grains that are thought to have condensed in the ejecta of cor…

Radioactive nuclei in the early Solar System: analysis of the 15 isotopes produced by core-collapse supernovae

Thomas V. Lawson, Marco Pignatari, Richard J. Stancliffe +5

Short-lived radioactive isotopes (SLRs) with half-lives between 0.1 to 100 Myr can be used to probe the origin of the Solar System. In this work, we examine the core-collapse super…
