Open-source framework for rapid stellar classification with Roman

The three Roman Core Community Surveys and the first announced General Astrophysics Survey (the Galactic Plane Survey) together are expected to obtain multi-band photometry for tens of billions of stars, an order of magnitude more than all other existing surveys combined.

This Roman photometry will enable stellar classification en masse across the Galactic disk and halo, underpinning a broad range of investigations in Galactic structure, star formation, stellar populations, galaxy evolution, and exoplanet demographics. The proposal adds Roman-centric functionality to brutus, a publicly available open-source stellar classification package already validated on a billion stars in the Galactic disk and halo.
