Abstract
AbstractThis work sketches how SDSSugrcolors and Kepler 2 in halo fields can identify red giants 50–100 kpc distant with minimal metallicity bias. For these mildly-reddened, metal-poor giants, (g-r)oyields the effective temperatureTeffto 100 K. K2 can detect the p-mode oscillations of red giants and measure their frequency of maximum power νmax. This sets the luminosityLboland thus the distance, plus an estimate of metallicity [Fe/H].
