Isotope variations of nucleosynthetic origin among solar system solid samples are well documented, yet the origin of these variations is still uncertain. The observed variability of 54Cr among materials formed in different regions of the protoplaneta...

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., …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...

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.

Evaluation of the N 13 (α,p) O 16 thermonuclear reaction rate and its impact on the isotopic composition of supernova grains (2020)
Journal Article
Meyer, A., De Séréville, N., Laird, A. M., Hammache, F., Longland, R., Lawson, T., …Tatischeff, V. (2020). Evaluation of the N 13 (α,p) O 16 thermonuclear reaction rate and its impact on the isotopic composition of supernova grains. Physical Review C, 102(3), Article 035803. https://doi.org/10.1103/PhysRevC.102.035803

Background: It has been recently suggested that hydrogen ingestion into the helium shell of massive stars could lead to high C13 and N15 excesses when the shock of a core-collapse supernova passes through its helium shell. This prediction questions t... Read More about Evaluation of the N 13 (α,p) O 16 thermonuclear reaction rate and its impact on the isotopic composition of supernova grains.
