The fate of massive single stars: exploring the impact of rotation and metallicity (2024)
Thesis
Chambers, C. S. The fate of massive single stars: exploring the impact of rotation and metallicity. (Thesis). Keele University. Retrieved from https://keele-repository.worktribe.com/output/1018847

The fate of massive stars depends largely on the mass and structure of their inner cores, and the composition of their envelopes at death. This is dependent on the mass loss history of the star, which has significant effects on the evolution of massi...

Hydrodynamic simulations of convection and nucleosynthesis in the late phases of massive stars to constrain and guide stellar evolution theory (2023)
Thesis
Rizzuti, F. (2023). Hydrodynamic simulations of convection and nucleosynthesis in the late phases of massive stars to constrain and guide stellar evolution theory. (Thesis). Keele University. Retrieved from https://keele-repository.worktribe.com/output/674565

The present knowledge of stellar evolution is still limited today by large uncertainties that derive from the complex multi-dimensional processes occurring in stars. Among them, the turbulent motions of the stellar fluid control the size and evolutio...

Internal mixing processes in massive stars: uncertainties and impact (2022)
Thesis
Kaiser, E. (2022). Internal mixing processes in massive stars: uncertainties and impact. (Thesis). Keele University

Massive stars are key contributors to the evolution of galaxies and many observed phenomena. Therefore, understanding them is crucial to explain the evolution of the Universe and its constituents. The evolution of massive stars is strongly in uenced... Read More about Internal mixing processes in massive stars: uncertainties and impact.

Convective boundary structure and mixing in stellar interiors (2021)
Thesis
Scott, L. J. A. (2021). Convective boundary structure and mixing in stellar interiors. (Thesis). Keele University

The treatment of convection remains one of the key uncertainties in stellar evolution. In particular, mixing processes at the boundaries of convective regions are complex and diffcult to define analytically. Therefore, hydrodynamic simulations are us...

Combining asteroseismic and s-process nucleosynthesis observations to constrain the evolution of rotating low-mass stars (2020)
Thesis
den Hartogh, J. W. (2020). Combining asteroseismic and s-process nucleosynthesis observations to constrain the evolution of rotating low-mass stars. (Thesis). Keele University

In this thesis, I study the evolution of low-mass (around 2 M?) solar-metallicity stars including the effect of rotation and magnetic fields. These stars produce a significant amount of elements heavier than iron via the so-called s process and thus...
