Title: Precise Masses of Young Stars in Taurus: Finishing the Job on Elias 12
Abstract: We are near our goal of measuring the masses of the binary components in Elias 12N and NTT 045251+3016 to better than 10% and determining the masses of T Tau Sa and Sb dynamically. This level of precision is important to validate and distinguish among theoretical calculations of PMS evolution. We have reached this point thanks to consistent assignments of time. The proposed imaging and spectroscopic measurements will enable us to complete the job of mapping the orbits on these young binaries, lay critical groundwork for longer period systems in our sample, and allow us to examine the rotational properties of the components in young multiple systems.
