There is an ever-growing abundance of stellar surveys exploring the formation and evolution of our galaxy. These surveys collect and derive the properties for 100,000s of stars, which can also be used to better understand the properties of planet-hosts across the Milky Way.
My talk will showcase how valuable such surveys can be to the exoplanet community through my dissertation work using the galactic archaeology survey known as GALAH. I have been able to use GALAH, along with other surveys to better characterize both the chemical and physical properties of stars observed by the TESS mission. This has led to learning more about the stellar populations of planet-hosts across the Galaxy to uncover clues towards the formation mechanisms of ultra-short period planets. I will also show how my work is useful for exogeologists in calculating the potential compositions of newly found worlds, to better understand their potential habitability.
