A Continuous Theory of Stellar System Formation

A satisfying theory for star or planet formation should not consider these processes in isolation. With the power of recent observational surveys, we are well positioned to test detailed theoretical models of multiple-star formation and orbital evolution across diverse galactic environments. Simultaneously we can begin to couple our understanding of the earliest phases of star formation with the onset of planetary system formation. I will review current theoretical and observational progress on multiple star formation, and highlight areas of continued uncertainty.
