cds-question@unistra.frasteroseismologygiant-starsastronomical-modelsIn the power spectra of oscillating red giants, there are visually distinct features defining stars ascending the red giant branch from those that have commenced helium core burning. We train a 1D convolutional neural network by supervised learning to automatically learn these visual features from images of folded oscillation spectra. By training and testing on Kepler red giants, we achieve an accuracy of up to 99 per cent in separating helium-burning red giants from those ascending the red giant branch. The convolutional neural network additionally shows capability in accurately predicting the evolutionary states of 5379 previously unclassified Kepler red giants, by which we now have greatly increased the number of classified stars.2017MNRAS.469.4578Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/469/4578CatalogResearchIsServedByTAP 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/469/4578https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/469/4578http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/469/4578https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/469/4578https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/469/4578http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/469/4578GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/469/4578/test (*Population class predictions for 1008 Kepler red giants (test set))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/469/4578/test?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/469/4578/test?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/469/4578/test?GETtext/xml+votable180.050000true291.0561836.70404110.005555555555555556Cone search capability for table J/MNRAS/469/4578/unclass (*Population class predictions for 7655 Kepler red giants (the unclassified set))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/469/4578/unclass?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/469/4578/unclass?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/469/4578/unclass?GETtext/xml+votable180.050000true291.0558836.55995190.0055555555555555564/922-923 933-935 944-946 5/3645-3647 3683 3704 3706 3729-3731 3760 3788-3789 3792 6/14567 14573 14575 14577-14579 14730-14731 14738 14744 14746-14747 14749-14751 14792 14794-14795 14822 14828 14830 14914-14915 15044-15045 15057 15059-15062 15160-15161 15172-15174 15176-15178 15200 15202 15232-15233https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/469/4578?format=asciidefaultJ/MNRAS/469/4578/test*Population class predictions for 1008 Kepler red giants (test set)recnoRecord number assigned by the VizieR team.
