- The origin of stardust in the Solar System, by comparing our models of asymptotic giant
branch (AGB) stars to cosmochemistry signatures such as the compositon of
microscopic meteoritic stardust:
- The connection between nucleosynthesis and asteroseismology: we are including the full s process network in the open source MESA, to understand neutron captures in AGB stars beyond the impact of rotation towards the effect of magnetic fields and to compare with asteroseismology observations of the core rotation of giant stars.
- Neutron capture processes intermediate between slow and rapid (the i process), their potential stellar sites and observational signatures.
- The production of radioactive nuclei in stars and supernovaes to understand the origin
of the Solar System by dating of events that happened before the birth of the Sun. Our current
picture of the timing of the last stellar event that added radioactive nuclei to the
presolar system matter is schematically shown below:
