Progenitors of Core-Collapse Supernovae (2017)
Journal Article
Hirschi, R., Arnett, D., Cristini, A., Georgy, C., Meakin, C., & Walkington, I. (2017). Progenitors of Core-Collapse Supernovae. Proceedings of the International Astronomical Union, 12(S331), 1-10. https://doi.org/10.1017/S1743921317004896

Massive stars have a strong impact on their surroundings, in particular when they produce a core-collapse supernova at the end of their evolution. In these proceedings, we review the general evolution of massive stars and their properties at collapse... Read More about Progenitors of Core-Collapse Supernovae.

Impact of Rotation and Convective Boundary Mixing in Low Mass AGB Stars (2017)
Journal Article
den Hartogh, J., Battino, U., Hirschi, R., Pignatari, M., & Herwig, F. (2017). Impact of Rotation and Convective Boundary Mixing in Low Mass AGB Stars. JPS Conference Proceedings, https://doi.org/10.7566/jpscp.14.020904

After central He burning exhaustion, stars with an initial mass of 1.5–3 solar masses start the AGB phase. In this phase, the s-process takes place, which is producing about half of all elements heavier than iron. We calculated non-rotating AGB stell...

Impacts of Nuclear-Physics Uncertainty in Stellar Temperatures on the s-Process Nucleosynthesis (2017)
Journal Article
Nishimura, N., Cescutti, G., Hirschi, R., Rauscher, T., Den Hartogh, J., & Murphy, A. S. J. (2017). Impacts of Nuclear-Physics Uncertainty in Stellar Temperatures on the s-Process Nucleosynthesis. JPS Conference Proceedings, https://doi.org/10.7566/jpscp.14.020903

We evaluated the uncertainty relevant to s-process nucleosynthesis using a Monte-Carlo centred approach. We are based on a realistic and general prescription of temperature dependent uncertainty for the reactions. We considered massive stars for the...

Constraining the efficiency of angular momentum transport with asteroseismology of red giants: the effect of stellar mass (2017)
Journal Article
Eggenberger, P., Lagarde, N., Miglio, A., Montalbán, J., Ekström, S., Georgy, C., …Hirschi, R. (2017). Constraining the efficiency of angular momentum transport with asteroseismology of red giants: the effect of stellar mass. Astronomy & Astrophysics, 599, Article A18. https://doi.org/10.1051/0004-6361/201629459

Context. Constraints on the internal rotation of red giants are now available thanks to asteroseismic observations. Preliminary comparisons with rotating stellar models indicate that an undetermined additional process for the internal transport of an...
