Scientific paper

We present results of a survey of the blue side of the Red Giant Branch in the Ursa Minor and Draco dSph galaxies. Using the LRS, HRS and for the first time the MRS spectrographs on the Hobby-Eberly Telescope. This study covers potential post-AGB, AGB, very metal-poor star and extreemly young star candidates. Using literature photometry, radial velocities and proper motions as well as new radial velocities and high resolution abundance analysis, we present a cleaned color-magnitude diagram and a list of our confirmed members and non-members as well as their derived metallicities.
