WE PROPOSE TO OBSERVE AND MODEL SEVERAL WELL-STUDIED NEARBY MAIN SEQUENCE BINARY SYSTEMS AS FUNDAMENTAL ASTROPHYSICAL CALIBRATORS. WE SPECIFICALLY TARGET EITHER: 1) SYSTEMS WHERE SOLAR-LIKE OSCILLATIONS SHOULD BE DETECTABLE IN THE PRIMARY STAR AND THE SECONDARY STAR IS OF M SPECTRAL TYPE AND 2) BINARIES WHERE BOTH PRIMARY AND SECONDARY STARS SHOULD BE DETECTABLE IN SOLAR-LIKE OSCILLATIONS. THESE SYSTEMS ARE FUNDAMENTAL ANCHORS WHERE BINARY ANALYSIS ASTROMETRY ASTEROSEISMOLOGY AND ROTATION- AND ACTIVITY BASED STELLAR CHARACTERIZATION METHODS---PARTICULARLY FOR AGE INFERENCE--- CAN BE TESTED UNIFIED AND PLACED ON INTERNALLY CONSISTENT GROUNDS. THIS CLASS OF FUNDAMENTAL CALIBRATORS IS UNUSUALLY ACCESSIBLE WITH GROUND-BASED RESOURCES FOR DETAILED CHARACTERIZATION IN COMPARISON TO THE FAINTER AND MORE DISTANT OPEN CLUSTERS.
