cds-question@unistra.frgiant-starsphotometryvariable-starsstellar-massesOf the more than 150000 targets followed by the Kepler Mission, about 10% were selected as red giants. Due to their high scientific value, in particular for Galaxy population studies and stellar structure and evolution, their Kepler light curves were made public in late 2011. More than 13000 (over 85%) of these stars show intrinsic flux variability caused by solar-like oscillations making them ideal for large-scale asteroseismic investigations. We automatically extracted individual frequencies and measured the period spacings of the dipole modes in nearly every red giant. These measurements naturally classify the stars into various populations, such as the red giant branch, the low-mass (M/M_{sun}_<~1.8) helium-core-burning red clump, and the higher-mass (M/M_{sun}_>~1.8) secondary clump. The period spacings also reveal that a large fraction of the stars show rotationally induced frequency splittings. This sample of stars will undoubtedly provide an extremely valuable source for studying the stellar population in the direction of the Kepler field, in particular when combined with complementary spectroscopic surveys.2013ApJ...765L..41Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/765/L41CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)J/ApJS/211/2 : Revised stellar properties of Q1-16 Kepler data (Huber+, 2014)J/ApJS/210/1 : Asteroseismic study of solar-type stars (Chaplin+, 2014)J/ApJS/199/30 : Effective temperature scale for KIC (Pinsonneault+, 2012)J/ApJ/753/90 : K5 & later type Kepler stars stellar parameters (Mann+, 2012)J/ApJ/752/72 : Correlation metallicity/eclipse depth (Dodson-Robinson, 2012)J/A+A/543/A160 : Normalized spectra of 82 Kepler red giants (Thygesen+, 2012)J/A+A/540/A143 : Oscillations of red giants observed by Kepler (Mosser+, 2012)J/A+A/531/A124 : Visibilities of stellar oscillation modes (Ballot+, 2011)J/A+A/528/A121 : Normalized spectra of 20 red giants (Bruntt,+, 2011)J/A+A/525/A131 : Solar-like oscillations in Kepler red giants (Hekker+, 2011)J/MNRAS/412/1210 : Kepler asteroseismic targets (Molenda-Zakowicz+, 2011)J/ApJ/718/L97 : Early asteroseismic results from Kepler (Van Grootel+, 2010)http://archive.stsci.edu/kepler/ : Kepler STSci archivehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/765/L41https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/765/L41http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/765/L41https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/765/L41https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/765/L41http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/765/L41GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/765/L41/fig4 (Median {Delta}P for each star versus its {Delta}{nu} (based on 0.2uHz smoothing of the frequency spectra))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/765/L41/fig4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/765/L41/fig4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/765/L41/fig4?GETtext/xml+votable180.050000true286.3057946.98989890.0055555555555555564/922 923 933 934 935 944 945 5/3645 3646 3647 3683 3704 3706 3729 3730 3731 3760 3784 3785 3786 3788 3789 3792 6/14567 14573 14575 14577 14578 14579 14730 14731 14738 14744 14746 14747 14749 14750 14751 14792 14794 14795 14822 14828 14830 14831 14914 14915 15044 15045 15057 15059 15060 15061 15062 15148 15149 15150 15160 15172 15173 15174 15178 15200 15232https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/765/L41?format=asciiOpticaldefaultJ/ApJ/765/L41/fig4Median {Delta}P for each star versus its {Delta}{nu} (based on 0.2uHz smoothing of the frequency spectra)KICKepler Input Catalog identifiermeta.id;meta.mainintprimaryDnu[3/16.6] Large frequency separation of consecutive overtone modes of the same degreeuHzem.freq;src.varfloat<DP>[8.1/319.5] Median pairwise period spacing between adjacent dipole modes (see section 2.3)stime.period;stat.medianfloatM[0.4/3.5] Stellar masssolMassphys.massfloatClassAsteroseismic classification: RGB (1869 objects), CLUMP (1231 objects), or UNKNOWN (226 objects))src.classchar_RAPositions from Kepler Input Catalog catalog (V/133) (right ascension part)degpos.eq.ra;meta.main_DEPositions from Kepler Input Catalog catalog (V/133) (declination part)degpos.eq.dec;meta.main
