Results in brief

Advancing nucleosynthesis predictions with modern supernova simulations

Core-collapse supernova (CCSN) explosions mark the end of the life of stars heavier than 10 times the mass of our sun, they play a crucial role for our understanding of the chemical composition of the universe and they are ideal laboratories for effects of neutrino and particle physics. Current research in astrophysics, astronomy and cosmochemistry that makes use of theoretical CCSN models for comparing to observations, still, however, relies predominantly on one-dimensional, i.e., spherically symmetric parameterized calculations. During the last decade, however, multi-dimensional and nearly parameter-free simulation have become possible. These advances have demonstrated that multi-dimensional simulations predict a wide variety of conditions that cannot be found in simple 1D models, but it remains unclear if they can solve some of the disagreements between observations and theoretical supernova models. This project aims at advancing the state-of-the-art by calculating the detailed composition of CCSN material (i.e., isotopic nucleosynthesis yields) based on the most recent, first-principles 3D simulations and by providing the results to the community. Since the landscape of supernova explosions spans a wide range of possible initial conditions, such as a star's initial mass, its initial composition and its environment (e.g., in a multiple system), a wide range of models needs to explored to capture the whole diversity of possible outcomes. This project, thus, constitutes a fist step, focussing on a few models for single stars, but it aims to provide the key elements to easily extend the approach to illuminate the full role of supernovae for the origin of the elements.

Project objective

Core-collapse supernova (CCSN) explosions mark the end of the life of stars heavier than 10 times the mass of our sun, they play a crucial role for our understanding of the chemical composition of the universe and they are ideal laboratories for effects of neutrino and particle physics. Current research in astrophysics, astronomy and cosmochemistry that requires theoretical CCSN models still, however, relies predominantly on one-dimensional, i.e., spherically symmetric parameterized calculations. This project aims at advancing the state-of-the-art by calculating the composition of CCSN material based on the most recent, first-principles 3D simulations and by providing the results to the community in accordance with FAIR data management principles. The researcher's background in nuclear and neutrino physics will also allow him to study the implications of uniquely multi-dimensional asymmetries in the neutrino emission and the consequences of neutrino flavor conversions, a quantum effect that changes the particles' spectra, for nucleosynthesis, both of which have never been explored and may lead to observational signatures. To achieve the goals, a new and innovative framework for nucleosynthesis calculations at the Max-Planck Institute for Astrophysics in Garching will be developed, based on an open-source reaction network code, which the researcher has contributed to and that he will apply to unique cutting-edge models. The fellow will obtain in-depth knowledge about supernovae and learn state-of-the-art techniques from the world-class team of Prof. Janka and apply them. He will broaden the scope of his work, complemented by a career development plan, training courses and coaching as well as detailed dissemination and public outreach plans to maximize the impact of the project's outcome. The completion of the project will allow the fellow to become a mature and independent scientist, well-recognized in his field of research.
