Inferring Galactic Parameters from Chemical Abundances: A Multi-Star Approach

1 code implementation2 Sep 2019 Oliver Henry Edward Philcox, Jan Rybizki

Constraining parameters such as the initial mass function high-mass slope and the frequency of type Ia supernovae is of critical importance in the ongoing quest to understand galactic physics and create realistic hydrodynamical simulations.

On the Optimal Choice of Nucleosynthetic Yields, IMF and Number of SNe Ia for Chemical Evolution Modelling

2 code implementations15 Dec 2017 Oliver Philcox, Jan Rybizki, Thales Gutcke

To fully harvest the rich library of stellar elemental abundance data available, we require reliable models that facilitate our interpretation of them.

$\mathit{Chempy}$: A flexible chemical evolution model for abundance fitting - Do the Sun's abundances alone constrain chemical evolution models?

3 code implementations28 Feb 2017 Jan Rybizki, Andreas Just, Hans-Walter Rix

A Chempy model is specified by a set of 5-10 parameters that describe the effective galaxy evolution along with the stellar and star-formation physics: e. g. the star-formation history, the feedback efficiency, the stellar initial mass function (IMF) and the incidence of supernova type Ia (SN Ia).
