My research involves exploring how stars form in disc galaxies through numerical simulations. I am particularly interested in how a galaxy’s structure affects its star formation and, in turn, how the formation of stars impacts the galaxy’s own evolution. From observations, we know many galaxies show a beautiful spiral structure, including our own Milky Way. Stars born within the spiral arms might experience very different conditions from those forming between the arms or in the outer part of the disc. This is one method in which the galaxy’s shape might affect a star’s evolution. Another area concerns whether stars can be formed during collisions between clouds of cold gas. Possibly, the highest mass stars in our galaxy are born through such a mechanism, with the collision rate governed by the way the gas flows through the galaxy’s structure. Working with the Theoretical Galaxy Group at Hokkaido and collaborating with groups in North America, Europe and Japan, my aim is to try and answer some of these questions.
