The Undergraduate Research series is where we feature the research that you’re doing. If you are an undergraduate that took part in an REU or similar astro research project and would like to share this on Astrobites, please check out our submission page for more details. We would also love to hear about your more general research experience!

There is no way to watch a galaxy evolve in real time, but understanding galaxy evolution is crucial in developing our knowledge of the universe. Specifically, tracking the metallicity evolution of a galaxy is important because the abundance of elements within a galaxy can give strong insight into the physical processes that have occurred within the galaxy. One of the only tools we have to understand galaxy evolution is the observation of stars within galaxies today. The goal of my project was to create a model that predicts the evolution of dwarf galaxy metallicity based on the observable properties of the galaxy: stellar metallicity and star formation rate.We created the ...
