THE KEPLER/K2 MISSION HAS REVOLUTIONIZED ASTEROSEISMOLOGY BY DETECTING OSCILLATIONS IN THOUSANDS OF STARS FROM THE MAIN-SEQUENCE TO THE RED GIANT BRANCH. BY PROVIDING ACCURATE RADII MASSES AND AGES THESE STARS HAVE BECOME BENCHMARKS FOR ADDRESSING PROBLEMS IN STELLAR ASTROPHYSICS EXOPLANET SCIENCE AND GALACTIC ASTRONOMY SUCH AS AGE-ROTATION RELATIONSHIPS FOR SOLAR-TYPE STARS THE COMPOSITION OF SUPER-EARTH SIZED PLANETS AND THE STUDY OF GALACTIC STELLAR POPULATIONS. HOWEVER OUR SAMPLE OF DWARFS AND SUBGIANTS WITH ASTEROSEISMIC DATA IS SMALL BECAUSE DETECTION REQUIRES SCARCE SHORT CADENCE IMAGING AND ONLY A FRACTION OF THE SHORT CADENCE TARGETS IN KEPLER HAVE BEEN CHARACTERIZED. BY CONTRAST THERE IS A RICH DATA SET OF RED GIANT ASTEROSEISMOLOGY FROM KEPLER AND K2 BUT THE DWELL TIME FOR K2 AND TESS IS TOO SHORT TO DETECT ASTEROSEISMIC SIGNALS DIRECTLY IN LUMINOUS AND SCIENTIFICALLY INTERESTING TARGETS. IN THIS PROPOSAL WE ADDRESS BOTH PROBLEMS CAPITALIZING ON THE VASTLY IMPROVED CLASSIFICATION OF KEPLER/K2 TARGETS PROVIDED BY GAIA PARALLAXES. WE WILL FIRST DRAMATICALLY INCREASE THE SIZE OF THE HIGH-QUALITY DWARF AND SUBGIANT ASTEROSEISMIC SAMPLE FROM KEPLER. WE PROPOSE A HOMOGENEOUS ANALYSIS OF THE RECENTLY RE-PROCESSED Q1-17 KEPLER SHORT-CADENCE DATA WHICH CORRECTED DATA CALIBRATION ERRORS THAT AFFECTED PRIOR SEISMIC ANALYSIS EFFORTS. FOR DWARFS AND SUBGIANTS WE WILL COMBINE WELL TESTED FREQUENCY-AUTOCORRELATION METHODS WITH GROUND-BASED SPECTROSCOPY AND ADAPTIVE OPTICS IMAGING TO COMPILE A LEGACY CATALOG OF ASTEROSEISMIC OBSERVABLES FUNDAMENTAL PARAMETERS AND POSSIBLE COMPANION STARS. FURTHERMORE WE WILL CALIBRATE STELLAR GRANULATION DIAGNOSTICS OF SURFACE GRAVITY FOR HIGH LUMINOSITY GIANTS USING DATA FROM THE ORIGINAL KEPLER MISSION STAR CLUSTERS AND GRAVITIES FROM GROUND-BASED SPECTROSCOPIC SURVEYS. BY APPLYING THIS NOVEL TECHNIQUE TO 12500 HIGH-LUMINOSITY GIANTS WE WILL SIGNIFICANTLY INCREASE THE REACH OF GALACTIC POPULATIONS STUDIED BY K2. OUR NOVEL METHOD WILL ALSO BE A PATHFINDER FOR ANALOGOUS APPLICATIONS TO THOUSANDS OF HIGH-LUMINOSITY GIANTS OBSERVED WITH TESS. COMBINED THESE DATASETS WILL ALLOW US TO 1) INVESTIGATE VARIATIONS IN AGE-ROTATION RELATIONSHIPS (GYROCHRONOLOGY) FOR SOLAR-TYPE STARS 2) IDENTIFY NEW ASTEROSEISMIC EXOPLANET HOST STARS TO VALIDATE EXOPLANET POPULATION TRENDS SUCH AS THE "HOT SUPER-EARTH DESERT" AND THE GAP BETWEEN SUPER-EARTH AND SUB-NEPTUNE SIZED PLANETS 3) TEST THE RELATION BETWEEN STELLAR MULTIPLICITY AND OSCILLATION AMPLITUDES AND 4) DISCOVER DISTANT HIGH-LUMINOSITY HALO GIANTS OBSERVED BY K2 POTENTIALLY LEADING TO AN ENSEMBLE AGE MEASUREMENT OF THE GALACTIC HALO. OUR PROGRAM WILL PROVIDE LEGACY DATA PRODUCTS FOR ASTEROSEISMIC KEPLER/K2 STARS INCLUDING POWER SPECTRA ASTEROSEISMIC OBSERVABLES AND FUNDAMENTAL PARAMETERS. THESE PRODUCTS WILL BE OF ENORMOUS VALUE FOR A VARIETY OF TOPICS IN STELLAR ASTROPHYSICS AND EXOPLANET SCIENCE INCLUDING GYROCHRONOLOGY TESTS OF STELLAR INTERIOR MODELS AND CALIBRATIONS OF INDIRECT METHODS SUCH AS SPECTROSCOPY. BENCHMARK STARS WITH WELL DETERMINED FUNDAMENTAL PROPERTIES ARE ALSO ESSENTIAL FOR THE ACCURATE CHARACTERIZATION OF EXOPLANETS WITH FUTURE NASA MISSIONS SUCH AS TESS JWST AND WFIRST.
