Project Description

The story of the origin of the elements fascinates mankind and touches many branches of science. This
project combines new stellar population models of the oldest stars with new data from the Australian millionstar
GALactic Archaeology with HERMES (GALAH) survey to address basic astrophysical problems: mixing
in stars, mass transfer in binary stars and measurement of the masses of the first stars. Knowing how these
ancient stars behave is crucial to understanding element production in the early Universe, both in our Milky
Way and distant galaxies. By statistically comparing my new models to the GALAH data, the masses of the
oldest Galactic stars will be measured, directly impacting branches of astrophysics from planets to galaxies.
