cds-question@unistra.frasteroseismologygiant-starsWe analysed solar-like oscillations in 1523 Kepler red giants which have previously been misclassified as subgiants, with predicted {nu}_max_ values [based on the Kepler Input Catalogue (KIC)] between 280 and 700{mu}Hz. We report the discovery of 626 new oscillating red giants in our sample, in addition to 897 oscillators that were previously characterized by Hekker et al. from one quarter of Kepler data. Our sample increases the known number of oscillating low-luminosity red giants by 26 per cent (up to >=1900 stars). About three quarters of our sample are classified as ascending red giant branch stars, while the remainder are red-clump stars. A novel scheme was applied to determine {Delta}{nu} for 108 stars with {nu}_max_ close to the Nyquist frequency (387{mu}Hz>{nu}_max_>387{mu}Hz). Additionally, we identified 47 stars oscillating in the super-Nyquist frequency regime, up to 387 {mu}Hz, using long-cadence light curves. We show that the misclassifications are most likely due to large uncertainties in KIC surface gravities, and do not result from the absence of broad-band colours or from different physical properties such as reddening, spatial distribution, mass or metallicity. The sample will be valuable to study oscillations in low-luminosity red giants and to characterize planet candidates around those stars.2016MNRAS.463.1297Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/463/1297CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/463/1297https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/463/1297http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/463/1297https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/463/1297https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/463/1297http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/463/1297GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/463/1297/table1 (Global oscillation parameters: {nu}_max_, {Delta}{nu} and amplitude)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/463/1297/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/463/1297/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/463/1297/table1?GETtext/xml+votable180.050000true291.1438336.7901310.0055555555555555564/922 933 935 944-946 5/3645-3647 3683 3694 3706 3729-3731 3736-3737 3739 3788-3789 3792-3793 6/14567 14573 14575 14578-14579 14730-14731 14744 14746 14750 14769-14772 14781-14783 14792 14818-14819 14828 14830 14914-14915 14952-14953 14955 15040-15041 15044-15045 15057 15059-15060 15062 15160 15176 15178 15200 15232https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/463/1297?format=asciidefaultJ/MNRAS/463/1297/table1Global oscillation parameters: {nu}_max_, {Delta}{nu} and amplituderecnoRecord number assigned by the VizieR team.
