    A search for p-modes and other variability in the binary system 85 Pegasi using MOST photometry 
    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 ...

    Stellar model analysis of the oscillation spectrum of [eta] Bootis obtained from MOST 
    Guenther, David B.; Kallinger, T.; Reegen, P.; Weiss, W. W.; Matthews, J. M.; Kuschnig, R.; Marchenko, S.; Moffat, A. F. J.; Rucinski, S. M.; Sasselov, D.; Walker, G. A. H. (American Astronomical Society, 2005-12-10)
    Eight consecutive low-frequency radial p-modes are identified in the G0 IV star [eta] Bootis based on 27 days of ultraprecise rapid photometry obtained by the MOST (Microvariability and Oscillations of Stars) satellite. ...

    Stellar modelling of Spica, a high-mass spectroscopic binary with a [beta] Cep variable primary component 
    Tkachenko, A.; Matthews, J. M.; Aerts, C.; Pavlovski, K.; Papics, P. I.; Zwintz, K.; Cameron, C.; Walker, G. A. H.; Kuschnig, R.; Degroote, P.; Guenther, David B. (Oxford University Press, 2016-05-11)
    Binary stars provide a valuable test of stellar structure and evolution, because the masses of the individual stellar components can be derived with high accuracy and in a model-independent way. In this work, we study ...

    V473 Lyr, a modulated, period-doubled Cepheid, and U TrA, a double-mode Cepheid, observed by MOST 
    Molnar, L.; Derekas, A.; Szabo, R.; Matthews, J. M.; Cameron, C.; Moffat, A. F. J.; Richardson, N. D.; Csak, B.; Dozsa, A.; Reed, P.; Szabados, L.; Heathcote, B.; Bohlsen, T.; Cacella, P.; Luckas, P.; Sodor, A.; Skarka, M.; Szabo, Gy. M.; Plachy, E.; Kovacs, J.; Evans, N.

F.; Cwiek, A.; Sokolowski, M.; Pal, A.; Guenther, David B.; Kuschnig, R.; Rowe, J.; Rucinski, S. M.; Sasselov, D.; Weiss, W. W. (Oxford University Press, 2017-05)
    Space-based photometric measurements first revealed low-amplitude irregularities in the pulsations of Cepheid stars, but their origins and how commonly they occur remain uncertain. To investigate this phenomenon, we present ...
