Chemical evolution

Several of our projects have explored the application of our NuGrid yields and other yields to chemical evolution models. For this purpose Christian Ritter and Benoit Côté have developed NuPyCEE.

Uncertainties in Galactic Chemical Evolution Models

Galactic chemical evolution models allow to follow in time the contribution of multiple stellar populations on the production of all elements in a galaxy. Here we present the impact of input uncertainties, such as the initial mass function, on chemical evolution predictions.

Numer of Masses and Metallicities in Grids of Stellar Models

Stellar yields are crucial inputs for galactic chemical evolution models. Here we investigate the impact of the stellar remnant mass distribution and the resolution of a set of stellar yields on the evolution of light elements.

Probing Nuclear Astrophysics with Galactic Chemical Evolution

Galactic chemical evolution models are perfect tools to probe nuclear astrophysics uncertainties. Here we show how tight chemical evolution predictions are to the choice of input stellar yields.

Galactic Chemical Evolution Pipeline

Galactic chemical evolution involves nuclear physics, stellar evolution, galaxy evolution, astronomical observations, and cosmology. Within the JINA-CEE and NuGrid collaborations, we are developing a numerical pipeline for creating permanent connections between all those fields to better understand the origin and evolution of the elements.
