A Closer Look at the Formation and Evolution of M31’s Inner Disk — this program leverages the unique spectroscopic and imaging capabilities of JWST to measure the chemical composition, velocities, and ages of stars across the disk of the Andromeda galaxy (M31) in a level of detail that has, until JWST, only been possible within our own Milky Way galaxy. This novel dataset will provide the first spatial profile of detailed star-by-star stellar chemistry in an external spiral galaxy as well as the most precise constraints on the historical star formation of M31’s inner disk to date.
