Predictions from -process AGB models of the isotopic variations of zirconium and neodymium for comparison to bulk meteorites
Maria Lugaro, Giulia C. Cinquegrana, Balázs Szányi +6
Bulk meteoritic data show isotopic variability of -neutron-capture (-process) origin in a several elements heavier than Fe. One peculiar feature is that the lighter -pr…

Asteroseismology of the G8 subgiant beta Aquilae with SONG-Tenerife, SONG-Australia and TESS
Hans Kjeldsen, Timothy R. Bedding, Yaguang Li +28
We present time-series radial velocities of the G8 subgiant star beta Aql obtained in 2022 and 2023 using SONG-Tenerife and, for the first time, SONG-Australia. We also analyse a s…

Structural and Nucleosynthetic Evolution of Metal-poor & Metal-free Low- and Intermediate-Mass Stars
Simon Wattana Campbell
In this PhD thesis we investigate stellar evolution and nucleosynthesis in the low- and extremely-low metallicity regime - including models of stars with a pure Big Bang compositio…
