Saint Mary's University Institutional Repository

Welcome to the Saint Mary's University institutional repository. This digital service holds research and teaching materials created by the Saint Mary's University community, including archival images, theses, faculty projects, and University publications, as well as other special campus collections. Items are being added every day, so come back again to see what is new.

  • Guenther, David B.; Hatzes, A. P.; Zechmeister, M.; Matthews, J.; Kuschnig, R.; Walker, G. A. H.; Dollinger, M.; Moffat, A. F. J.; Rucinski, S. M.; Sasselov, D. (European Southern Observatory, 2012)
    Aims. Our aim is to use precise radial velocity measurements and photometric data to derive the frequency spacing of the p-mode oscillation spectrum of the planet-hosting star [beta] Gem. This spacing along with the ...

  • Guenther, David B.; Gruberbauer, Michael; Huber, D.; Kuschnig, R.; Weiss, W. W.; Matthews, J. M.; Moffat, A. F. J.; Rowe, J. F.; Rucinski, S. M.; Sasselov, D. (EDP Sciences, 2011-06)
    We report on the analysis of high-precision space-based photometry of the roAp (rapidly oscillating Ap) stars HD 9289, HD 99563, and HD 134214. All three stars were observed by the MOST satellite for more than 25 days, ...

  • Guenther, David B.; Gruberbauer, Michael; Huber, D.; Matthews, J. M.; Croll, B.; Obbrugger, M.; Weiss, W. W.; Rowe, J. F.; Kallinger, T.; Kuschnig, R. (EDP Sciences, 2009-10)
    Context. Asteroseismology has great potential for the study of metal-poor stars due to its sensitivity to determine stellar ages. Solid detections of oscillation frequencies in stars with well constrained fundamental ...

  • Gruberbauer, Michael; Reegen, P.; Schneider, L.; Weiss, W. W. (EDP Sciences, 2008-06)
    Context. The identification of smaller and smaller signals from objects observed with a non-perfect instrument in a noisy environment poses a challenge for a statistically clean data analysis. Aims. We compute the probability ...

  • Guenther, David B.; Gruberbauer, Michael; Kallinger, T.; Weiss, W. W. (EDP Sciences, 2009-11)
    Aims. Deriving accurate frequencies, amplitudes, and mode lifetimes from stochastically driven pulsation is challenging, more so, if one demands that realistic error estimates be given for all model fitting parameters. As ...
