On the non-variability of HR 7653 (15 Vul) based on BRITE data (2018)
Journal Article
Smalley. (2018). On the non-variability of HR 7653 (15 Vul) based on BRITE data

We present space-based BRITE photometric observations of the metallic line (CP1) star HR 7653 (15 Vul). This chemically peculiar star of the upper main sequence was suspected to show variability due to rotation and a magnetic field. Such a variabilit...

Impact of rotation and magnetic fields in low mass AGB stars (2018)
Conference Proceeding
den Hartogh, J. W., Hirschi, R., Georgy, C., Eggenberger, P., Herwig, F., Pignatari, M., …Ritter, C. (2018). Impact of rotation and magnetic fields in low mass AGB stars. . https://doi.org/10.1088/1742-6596/940/1/012038

After core helium burning in low and intermediate-mass stars, starts the AGB phase. In this phase, the s process takes place, which is believed to be at the origin of half of all elements heavier than iron. The role of rotation and magnetic fields on...

Nucleosynthesis in the first massive stars (2018)
Journal Article
Hirschi. (2018). Nucleosynthesis in the first massive stars. Journal of Physics: Conference Series, 012021 -?. https://doi.org/10.1088/1742-6596/940/1/012021

The nucleosynthesis in the first massive stars may be constrained by observing the surface composition of long-lived very iron-poor stars born around 10 billion years ago from material enriched by their ejecta. Many interesting clues on physical proc... Read More about Nucleosynthesis in the first massive stars.

Sensitivity to neutron captures and ß -decays of the enhanced s-process in rotating massive stars at low metallicities (2018)
Journal Article

The s-process in massive stars, producing nuclei up to A ˜ 90, has a different behaviour at low metallicity if stellar rotation is significant. This enhanced s-process is distinct from the s-process in massive stars around solar metallicity, and deta...
