    A previously derived photometric parallax of 10.10 ± 0.20 mas, d = 99 ± 2 pc, is confirmed for Polaris by a spectroscopic parallax derived using line ratios in high dispersion spectra for the Cepheid. The ...


  • Saio, H.; Gruberbauer, Michael; Weiss, W. W.; Matthews, J. M.; Ryabchikova, T. (Oxford University Press, 2012-02)
    Precise time series photometry with the MOST satellite has led to identification of 10 pulsation frequencies in the rapidly oscillating Ap (roAp) star HD134214. We have fitted the observed frequencies with theoretical ...

    Background: Increasing the yield of barley (Hordeum vulgare L.) is a main breeding goal in developing barley cultivars. A high density genetic linkage map containing 1894 SNP and 68 SSR markers covering 1375.8 cM was ...

  • Harper, Karen A., 1969-; MacDonald, S. E. (Wiley, 2011-08-25)
    Despite many studies on edge influence in forests, there is no common method for estimating distance of edge influence (DEI, = edge width). We introduce a new randomization method (RTEI) for estimating DEI that tests the ...

  • Guenther, David B. (American Astronomical Society, 2004-09)
    We analyze the recent ground-based p-mode oscillation observations of [eta] Boo by Kjeldsen and his collaborators using a large and dense grid of stellar model oscillation spectra parameterized by mass, age, and metallicity. ...

  • Gallo, Luigi C.; Grupe, D.; Schartel, N.; Komossa, S.; Miniutti, G.; Fabian, A. C.; Santos-Lleo, M. (Oxford University Press, 2011-03)
    In 2009 March the well-studied quasar, PG 0844+349, was discovered with Swift to be in an X-ray weak state. A follow-up XMM–Newton observation several weeks later generated a good-quality spectrum of the source, showing ...

(Elsevier, 2019-08-10)
    The quasi-free scattering reactions 11C(p, 2p) and 10,11,12C(p, pn) have been studied in inverse kinematics at beam energies of 300–400 MeV/u at the ...

  • Deupree, Robert G. (Robert Gaston), 1946-; Lovekin, C. C. (American Astronomical SocietyIOP Publishing, 2008-06-01)
    We use two-dimensional stellar models and a two-dimensional finite difference integration of the linearized pulsation equations to calculate nonradial oscillations. This approach allows us to directly calculate the pulsation ...

  • Deupree, Robert G. (Robert Gaston), 1946-; Geroux, Chris M. (American Astronomical Society, 2011-04)
    We are developing a three-dimensional radiation hydrodynamics code to simulate the interaction of convection and pulsation in classical variable stars. One key goal is the ability to carry these simulations to full amplitude ...
