    Regular frequency patterns in the classical [delta] Scuti star HD 144277 observed by the MOST satellite 
    Zwintz, K.; Lenz, P.; Breger, M.; Pamyatnykh, A. A.; Zdravkov, T.; Kuschnig, R.; Matthews, J. M.; Guenther, David B.; Moffat, A. F. J.; Rowe, J. F. (EDP Sciences S.A., 2011-09)

    Context. We present high-precision time-series photometry of the classical δ Scuti star HD 144277 obtained with the MOST (Microvariability and Oscillations of STars) satellite in two consecutive years. The observed ...

    Solving the mode identification problem in asteroseismology of F stars observed with Kepler 
    White, Timothy R.; Bedding, Timothy R.; Gruberbauer, Michael; Benomar, Othman; Stello, Dennis; Appourchaux, Thierry; Chaplin, William J.; Christensen-Dalsgaard, Jorgen; Elsworth, Yvonne P.; Garcia, Rafael A. (IOP Publishing Limited, 2012-06-01)
    Asteroseismology of F-type stars has been hindered by an ambiguity in identification of their oscillation modes. The regular mode pattern that makes this task trivial in cooler stars is masked by increased line widths. The ...

    Sounding open clusters: asteroseismic constraints from Kepler on the properties of NGC 6791 and NGC 6819 
    Gruberbauer, Michael; Basu, Sarbani; Grundahl, Frank; Stello, Dennis; Kallinger, T.; Hekker, Saskia; Mosser, Benoit; Garcia, Rafael A.; Mathur, Savita; Brogaard, Karsten (American Astronomical Society, 2011-03-01)
    We present initial results on some of the properties of open clusters NGC 6791 and NGC 6819 derived from asteroseismic data obtained by NASA’s Kepler mission. In addition to estimating the mass, radius, and log g of stars ...

    Upper boundary condition for asteroseismological modelling of solar-type stars 
    Cooke, Kevin Christopher (Halifax, N.S. : Saint Mary's University, 2013)
    We present a grid of line blanketed spherical LTE model atmospheres and high resolution extinction spectra for use in interpolating an accurate outer boundary condition for asteroseismology calculations at arbitrary ...
