The Promise of Young Spectroscopic Binaries
Lisa Prato

T Tauri spectroscopic binaries (SBs) are valuable not only for the determination of young star masses, but also as precise probes for understanding binary star formation, a process responsible for at least 50% of all stars. Yet for only a few dozen systems of age <10 Myr have even the most basic measurements been made, and many of those are highly uncertain. I will describe the increasingly rich progress made with colleagues and student collaborators at growing the sample of young SBs with accurate and precise dynamical measurements, note new areas of inquiry that we are beginning to explore, such as spin-orbit alignment, and comment on some unusual and baffling systems.
