Journal of Physics G: Nuclear and Particle Physics, 49(11), Article 110502. https://doi.org/10.1088/1361-6471/ac8890

Nuclear astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the chemical elements. This white paper summarizes progress and status of... Read More about Horizons: nuclear astrophysics in the 2020s and beyond.

Galactic Chemical Evolution of Radioactive Isotopes with an s-process Contribution (2022)
Journal Article
Trueman, T. C. L., Côté, B., Yagüe López, A., Den Hartogh, J., Pignatari, M., Soós, B., Karakas, A. I., & Lugaro, M. (2022). Galactic Chemical Evolution of Radioactive Isotopes with an s-process Contribution. The Astrophysical journal, 924(1), 10. https://doi.org/10.3847/1538-4357/ac31b0

Analysis of inclusions in primitive meteorites reveals that several short-lived radionuclides (SLRs) with half-lives of 0.1-100 Myr existed in the early solar system (ESS). We investigate the ESS origin of 107Pd, 135Cs, and 182Hf, which are produced... Read More about Galactic Chemical Evolution of Radioactive Isotopes with an s-process Contribution.

Radioactive nuclei in the early Solar system: analysis of the 15 isotopes produced by core-collapse supernovae (2021)
Journal Article
Lawson, T. V., Pignatari, M., Stancliffe, R. J., Den Hartogh, J., Jones, S., Fryer, C. L., Gibson, B. K., & Lugaro, M. (2022). 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...

26Aluminum from Massive Binary Stars. II. Rotating Single Stars up to Core Collapse and Their Impact on the Early Solar System (2021)
Journal Article
Brinkman, H. E., Hartogh, J. W., Doherty, C. L., Pignatari, M., & Lugaro, M. (2021). 26Aluminum from Massive Binary Stars. II. Rotating Single Stars up to Core Collapse and Their Impact on the Early Solar System. The Astrophysical journal, 923(1), Article 47. https://doi.org/10.3847/1538-4357/ac25ea

Radioactive nuclei were present in the early solar system (ESS), as inferred from analysis of meteorites. Many are produced in massive stars, either during their lives or their final explosions. In the first paper of this series (Brinkman et al. 2019... Read More about 26Aluminum from Massive Binary Stars. II.

129I and 247Cm in meteorites constrain the last astrophysical source of solar r-process elements (2021)
Journal Article
Côté, B., Eichler, M., Yagüe, A., Vassh, N., Mumpower, M. R., Világos, B., Soós, B., Arcones, A., Sprouse, T. M., Surman, R., Pignatari, M., Pető, M. K., Wehmeyer, B., Rauscher, T., & Lugaro, M.

The composition of the early Solar System can be inferred from meteorites. Many elements heavier than iron were formed by the rapid neutron capture process (r-process), but the astrophysical sources where this occurred remain poorly understood. We de...
