    Oscillation mode frequencies of 61 main sequence and subgiant stars observed by Kepler 
    Appourchaux, T.; Chaplin, W. J.; Garcia, R. A.; Gruberbauer, Michael; Verner, G. A.; Antia, H. M.; Benomar, O.; Campante, T. L.; Davies, G. R.; Deheuvels, S. (EDP Sciences, 2012)
    Context. Solar-like oscillations have been observed by Kepler and CoRoT in several solar-type stars, thereby providing a way to probe the stars using asteroseismology. Aims. We provide the mode frequencies of the oscillations ...

    Quantitative analysis of the oscillation spectrum of [eta] Bootis 
    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. ...

    Seismology of [eta] Bootis 
    Guenther, David B.; Demarque, P. (American Astronomical Society, 1996-01)
    The p-mode frequencies recently observed by Kjeldsen and coworkers, along with other observables, are used to determine the mass, age, and helium abundance of [eta] Bootis. We show, by direct application, how the p-model ...

    Space- and ground-based pulsation data of [eta] Bootis explained with stellar models including turbulence 
    Straka, Christian W.; Demarque, Pierre; Guenther, David B.; Li, Linghuai; Robinson, Frank J. (American Astronomical SocietyIOP PUblishing, 2006-01-10)
    The space telescope MOST is now providing us with extremely accurate low-frequency p-mode oscillation data for the star [eta] Boo.We demonstrate in this paper that these data, when combined with ground-based measurements ...

    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. ...
