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), Article 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...

The chemical evolution of the solar neighbourhood for planet-hosting stars (2023)
Journal Article
Pignatari, M., Trueman, T. C., Womack, K. A., Gibson, B. K., Côte, B., Turrini, D., …Lugaro, M. (2023). The chemical evolution of the solar neighbourhood for planet-hosting stars. Monthly notices of the Royal Astronomical Society, 524(4), 6295-6330. 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., Lawson, T. V., Pignatari, M., Vaezzadeh, I., Côté, B., & Chongchitnan, S. (2021). Project ThaiPASS: international outreach blending astronomy and Python. Physics Education, 56(3), Article 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.

Nucleosynthetic yields from neutron stars accreting in binary common envelopes (2019)
Journal Article
Keegans, J. D., Fryer, C. L., Jones, S. W., Côté, B., Belczynski, K., Herwig, F., Pignatari, M., Laird, A. M., & 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

© 2019 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical Society. 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 com...
