cds-question@unistra.frasteroseismologyvariable-starsAsteroseismology is witnessing a revolution, thanks to high-precise asteroseismic space data (MOST, COROT, Kepler, BRITE) and their large ground-based follow-up programs. Those instruments have provided an unprecedented large amount of information, which allows us to scrutinize its statistical properties in the quest for hidden relations among pulsational and/or physical observables. This approach might be particularly useful for stars whose pulsation content is difficult to interpret. This is the case of intermediate-mass classical pulsating stars (i.e. {gamma} Dor, {delta} Scuti, hybrids) for which current theories do not properly predict the observed oscillation spectra. Here, we establish a first step in finding such hidden relations from data mining techniques for these stars. We searched for those hidden relations in a sample of {delta} Scuti and hybrid stars observed by COROT and Kepler (74 and 153, respectively). No significant correlations between pairs of observables were found. However, two statistically significant correlations emerged from multivariable correlations in the observed seismic data, which describe the total number of observed frequencies and the largest one, respectively. Moreover, three different sets of stars were found to cluster according to their frequency density distribution. Such sets are in apparent agreement with the asteroseismic properties commonly accepted for A-F pulsating stars.2017MNRAS.471.2491Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/471/2491CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/corot : CoRoT observation log (N2-4.4) (CoRoT 2016)V/133 : Kepler Input Catalog (Kepler Mission Team, 2009)J/A+A/534/A125 : Variability of A- & F-stars from Kepler (Uytterhoeven+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/471/2491https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/471/2491http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/471/2491https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/471/2491https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/471/2491http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/471/2491GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/471/2491/table4 (Seismic and physical observables of the stars used)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/471/2491/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/471/2491/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/471/2491/table4?GETtext/xml+votable180.050000true100.7097194-1.37574810.0055555555555555565/3694 3706 6/14573 14581-14586 14589 14731-14734 14746 14749 14751-14752 14755 14757 14759 14763-14765 14767 14769-14771 14775 14781-14782 14794-14795 14817 14819 14915 14917-14918 14921-14922 14928-14929 14931-14932 14939 14945 14947 14950 14953 14958 14960 14963 14966-14967 14969-14974 15057 15060-15062 15104 15107 15110-15111 15113 15115 15118-15119 15121-15122 15125-15126 15128 15132-15133 15136-15138 15140-15141 15145-15146 15148-15150 15154 15157 15169 15171-15172 22076 22078-22079 22122 22164-22165 22167 22208 22210https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/471/2491?format=asciidefaultJ/MNRAS/471/2491/table4Seismic and physical observables of the stars usedSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
