    Detection of solar-like oscillations in the red giant star [Epsilon] Ophiuchi by MOST spacebased photometry 
    Barban, C.; Matthews, J. M.; De Ridder, J.; Baudin, F.; Kuschnig, R.; Mazumdar, A.; Samadi, R.; Guenther, David B.; Moffat, A. F. J.; Rucinski, S. M. (EDP Sciences, 2007-06)
    Context. Solar-like oscillations have been discovered in a few red giants, including e Oph, through spectroscopy. Acoustic modes around 60 μHz were clearly seen in this star, but daily aliasing of the groundbased data ...

    The mass of the planet-hosting giant star [beta] Geminorum determined from its p-mode oscillation spectrum 
    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. (EDP Sciences, 2012-07)
    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 ...

    MOST detects corotating bright spots on the mid-O-type giant Xi Persei 
    Ramiaramanantsoa, Tahina; Moffat, Anthony F. J.; Chene, Andre-Nicolas; Richardson, Noel D.; Henrichs, Huib F.; Desforges, Sebastien; Antoci, Victoria; Rowe, Jason F.; Matthews, Jaymie M.; Kuschnig, Rainer; Guenther, David B. (Oxford University Press, 2014-06)
    We have used the MOST (Microvariability and Oscillations of STars) microsatellite to obtain four weeks of contiguous high-precision broad-band visual photometry of the O7.5III(n)((f)) star ξ Persei in 2011 November . ...

    Pulsation of the K 2.5 giant star GSC 09137-03505? 
    Guenther, David B.; Kallinger, T.; Zwintz, K.; Pamyatnykh, A. A.; Weiss, W. W. (EDP Sciences, 2005-04)
    In July, 1999, the Hubble Space Telescope (HST) pointed for more than 8 days continuously at the globular cluster 47 Tucanae. Two guide stars were used during this campaign by the Fine Guidance Sensors (FGS). Using more ...
