The radioisotope 26Al is a key observable for nucleosynthesis in the Galaxy and the environment of the early Solar System. To properly interpret the large variety of astronomical and meteoritic data, it is crucial to understand both the nuclear react

First models of s process in AGB stars of solar metallicity for the stellar evolutionary code ATON with a novel stable explicit numerical solver
Autor: A. Yagüe López, Scott Jones, Paolo Ventura, D. A. García-Hernández, J. W. den Hartogh, M. Lugaro, Carolyn Doherty
Aims. We describe the first s-process post-processing models for asymptotic giant branch (AGB) stars of masses 3, 4 and 5 M at solar metallicity (Z=0.018) computed using the input from the stellar evolutionary code aton. Methods. The models are compu

Asteroseismology of evolved stars to constrain the internal transport of angular momentum. III. Using the rotation rates of intermediate-mass stars to test the Fuller-formalism
Autor: S. Deheuvels, Patrick Eggenberger, J. W. den Hartogh
Context: The internal characteristics of stars, such as their core rotation rates, are obtained via asteroseismic observations. A comparison of core rotation rates found in this way with core rotation rates as predicted by stellar evolution models de

The s process in rotating low-mass AGB stars. Nucleosynthesis calculations in models matching asteroseismic constraints
Autor: Carolyn Doherty, Marco Pignatari, J. W. den Hartogh, Patrick Eggenberger, U. Battino, Maria Lugaro, Falk Herwig, Raphael Hirschi
Aims. We investigate the s-process during the AGB phase of stellar models whose cores are enforced to rotate at rates consistent with asteroseismology observations of their progenitors and successors. Methods. We calculated new 2M$_{\odot}$, Z=0.01 m

Constraining transport of angular momentum in stars Combining asteroseismic observations of core helium burning stars and white dwarfs
Autor: Patrick Eggenberger, Raphael Hirschi, J. W. den Hartogh
Transport of angular momentum has been a challenging topic within the stellar evolution community, even more since the recent asteroseismic surveys. All published studies on rotation using asteroseismic observations show a discrepancy between the obs

Asteroseismic measurements of the internal rotation of subgiants and red giants all show the need for invoking a more efficient transport of angular momentum than theoretically predicted. Constraints on the core rotation rate are available starting f

The main s-process taking place in low mass stars produces about half of the elements heavier than iron. It is therefore very important to determine the importance and impact of nuclear physics uncertainties on this process. We have performed extensi

Impacts of Nuclear-Physics Uncertainty in Stellar Temperatures on the s-Process Nucleosynthesis
Autor: Gabriele Cescutti, Nobuya Nishimura, Thomas Rauscher, J. W. den Hartogh, Raphael Hirschi, A. St. J. Murphy
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
