    Detection of long-period variations in the subdwarf B star PG 0101+039 on the basis of photometry from the MOST satellite 
    Randall, S. K.; Matthews, J. M.; Fontaine, G.; Rowe, J.; Kuschnig, R.; Green, E. M.; Brassard, P.; Chayer, P.; Guenther, David B.; Moffat, A. F. J. (American Astronomical Society, 2005-11-01)
    We report the detection of three discrete pulsation frequencies in the long-period variable subdwarf B star PG 0101+039 on the basis of ~400 hr of MOST wide-band photometry. The periodicities uncovered lie at 7235, 5227, ...

    Modelling dusty planetary disks using secular perturbation theory 
    Capobianco, Christopher Claudio (Halifax, N.S. : Saint Mary's University, 2006)
    Optical coronagraphic imaging of the circumstellar dust disk around β Pictoris reveals that the inner portion of the disk is warped, and this warp is typically attributed to the presence of a planetary system. Mouillet et ...

    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 ...
