Type Ia Supernova Nucleosynthesis: Metallicity-dependent Yields (2023)
Journal Article
Keegans, J. D., Pignatari, M., Stancliffe, R. J., Travaglio, C., Jones, S., Gibson, B. K., …Few, G. (2023). Type Ia Supernova Nucleosynthesis: Metallicity-dependent Yields. Astrophysical Journal Supplement, 268(1), 8. https://doi.org/10.3847/1538-4365/ace102

Type Ia supernova explosions (SN Ia) are fundamental sources of elements for the chemical evolution of galaxies. They efficiently produce intermediate-mass (with Z between 11 and 20) and iron group elements—for example, about 70% of the solar iron is...

The chemical evolution of the solar neighbourhood for planet-hosting stars (2023)
Journal Article
Pignatari, M., Trueman, T. C. L., Womack, K. A., Gibson, B. K., Côté, B., Turrini, D., …Lugaro, M. (in press). The chemical evolution of the solar neighbourhood for planet-hosting stars. Monthly Notices of the Royal Astronomical Society, https://doi.org/10.1093/mnras/stad2167

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 estimated ”pristine” compositions for stellar systems. The effective sc... Read More about The chemical evolution of the solar neighbourhood for planet-hosting stars.

Project ThaiPASS: international outreach blending astronomy and Python (2021)
Journal Article
Keegans, J. D., Stancliffe, R. J., Bilton, L. E., Cashmore, C. R., Gibson, B. K., Kristensen, M. T., …Chongchitnan, S. (2021). Project ThaiPASS: international outreach blending astronomy and Python. Physics Education, 56(3), 035001. https://doi.org/10.1088/1361-6552/abdae7

We present our outreach program, the Thailand–UK Python+Astronomy Summer School (ThaiPASS), a collaborative project comprising UK and Thai institutions and assess its impact and possible application to schools in the United Kingdom. Since its incepti... Read More about Project ThaiPASS: international outreach blending astronomy and Python.

Experimentally well-constrained masses of 27P and 27S: Implications for studies of explosive binary systems (2020)
Journal Article
Sun, L., Xu, X., Hou, S., Lin, C., José, J., Lee, J., …Zhao, Y. (2020). Experimentally well-constrained masses of 27P and 27S: Implications for studies of explosive binary systems. Physics Letters B, 802, Article 135213. https://doi.org/10.1016/j.physletb.2020.135213

The mass of 27P is expected to impact the X-ray burst (XRB) model predictions of burst light curves and the composition of the burst ashes, but large uncertainties and inconsistencies still exist in the reported 27P masses. We have used the β-decay s... Read More about Experimentally well-constrained masses of 27P and 27S: Implications for studies of explosive binary systems.

Nucleosynthetic yields from neutron stars accreting in binary common envelopes (2019)
Journal Article
Keegans, J., Fryer, C. L., Jones, S. W., Côté, B., Belczynski, K., Herwig, F., …Diget, C. A. (2019). Nucleosynthetic yields from neutron stars accreting in binary common envelopes. Monthly Notices of the Royal Astronomical Society, 485(1), 620-639. https://doi.org/10.1093/mnras/stz368

Massive-star binaries can undergo a phase where one of the two stars expands during its advanced evolutionary stage as a giant and envelops its companion, ejecting the hydrogen envelope and tightening its orbit. Such a common envelope phase is requir... Read More about Nucleosynthetic yields from neutron stars accreting in binary common envelopes.

Binding blocks: building the Universe one nucleus at a time (2017)
Journal Article
Diget, C. A., Pastore, A., Leech, K., Haylett, T., Lock, S., Sanders, T., …Collaboration, T. B. B. (2017). Binding blocks: building the Universe one nucleus at a time. Physics Education, 52(2), 024001. https://doi.org/10.1088/1361-6552/aa550c

We present a new teaching and outreach activity based around the construction of a three-dimensional chart of isotopes using $\text{LEG}{{\text{O}}^{\circledR}}$ bricks5. The activity, binding blocks, demonstrates nuclear and astrophysical processes... Read More about Binding blocks: building the Universe one nucleus at a time.
