Stellar evolution through the Red Supergiant phase
Sylvia Ekström, Cyril Georgy
Massive stars less massive than ~30 Msol evolve into a red supergiant after the main sequence. Given a standard IMF, this means about 80% of all single massive stars will experienc…
Very massive star winds as sources of the short-lived radioactive isotope Al
S. Martinet, G. Meynet, D. Nandal +7
The Al short-lived radioactive nuclide is the source of the observed galactic diffuse -ray emission at 1.8 MeV. While different sources of Al have been explored, s…
Dependence of Convective Boundary Mixing on Boundary Properties and Turbulence Strength
A. Cristini, R. Hirschi, C. Meakin +3
Convective boundary mixing is one of the major uncertainties in stellar evolution. In order to study its dependence on boundary properties and turbulence strength in a controlled w…
Extended Main Sequence Turnoffs in Open Clusters as Seen by Gaia: I. NGC 2818 and the Role of Stellar Rotation
N. Bastian, S. Kamann, I. Cabrera-Ziri +5
We present an analysis of the relatively low mass (~M), ~Myr, Galactic open cluster, NGC~2818, using Gaia DR2 results combined with VLT/FLAMES spectros…
First results from the LIFE project: discovery of two magnetic hot evolved stars
A. J. Martin, C. Neiner, M. E. Oksala +6
We present the initial results of the Large Impact of magnetic Fields on the Evolution of hot stars (LIFE) project. The focus of this project is the search for magnetic fields in e…
Testing a one-dimensional prescription of dynamical shear mixing with a two-dimensional hydrodynamic simulation
Philipp V. F. Edelmann, Friedrich K. Roepke, Raphael Hirschi +2
The treatment of mixing processes is still one of the major uncertainties in 1D stellar evolution models. This is mostly due to the need to parametrize and approximate aspects of h…
