The radioisotope 26Al is a key observable for nucleosynthesis in the Galaxy and the environment of the early Solar System. To properly interpret the large variety of astronomical and meteoritic data, it is crucial to understand both the nuclear react...

Isotopic ratios for C, N, Si, Al, and Ti in C-rich presolar grains from massive stars (2022)
Journal Article
Schofield, J., Pignatari, M., Stancliffe, R. J., & Hoppe, P. (2022). Isotopic ratios for C, N, Si, Al, and Ti in C-rich presolar grains from massive stars. Monthly notices of the Royal Astronomical Society, 517(2), 1803-1820. https://doi.org/10.1093/mnras/stac2498

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 core-collapse supernovae (CCSNe). In this work, we compare C, N, Al, Si, a... Read More about Isotopic ratios for C, N, Si, Al, and Ti in C-rich presolar grains from massive stars.

Radioactive nuclei in the early Solar system: analysis of the 15 isotopes produced by core-collapse supernovae (2021)
Journal Article

Radioactive nuclei in the early Solar system: analysis of the 15 isotopes produced by core-collapse supernovae. Monthly notices of the Royal Astronomical Society, 511(1), 886-902. https://doi.org/10.1093/mnras/stab3684

Short-lived radioactive isotopes (SLRs) with half-lives between 0.1 and 100 Myr can be used to probe the origin of the Solar system. In this work, we examine the core-collapse supernovae production of the 15 SLRs produced: 26Al, 36Cl, 41Ca, 53Mn, 60F...
