cds-question@unistra.frmilky-way-galaxygalactic-centervariable-starsphotometryvisible-astronomyWe have performed a frequency analysis of 10092 {delta} Scuti-type stars detected in the fourth phase of the Optical Gravitational Lensing Experiment towards the Galactic bulge, which is the most numerous homogeneous sample of {delta} Scuti stars observed so far. The main goal was to search for stars pulsating in at least two radial modes simultaneously. We have found 3083 candidates for such stars, which is the largest set obtained to date. Among them, 2655 stars pulsate in two radial modes, 414 stars pulsate in three radial modes, and 14 stars pulsate in four radial modes at the same time. We report the identification of 221 {delta} Scuti stars pulsating in the fundamental mode, first overtone, and third overtone simultaneously. We show the most populated Petersen and Bailey diagrams and discuss statistical properties of the identified frequencies based on this numerous sample. Additionally, we present theoretical predictions of period ratios for {delta} Scuti stars pulsating in overtones from the fourth to the seventh.2022MNRAS.510.1748Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/510/1748CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/71/189 : OGLE Galactic bulge and disk delta Scuti (Soszynski+, 2021)J/AcA/63/379 : OGLE-III variable stars in Galactic disk areaJ/AcA/52/129 : DIA OGLE2 candidate variable stars catalog (Wozniak+, 2002)J/AcA/59/239 : VI light curves of LMC long-period variables (Soszynski+, 2009)J/AcA/64/177 : VI light curves of Galactic Bulge RR Lyrae (Soszynski+, 2014)http://www.astrouw.edu.pl/ogle/ogle4/OCVS/blg/dsct/ : OGLE online data archivehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/510/1748https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/510/1748http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/510/1748https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/510/1748https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/510/1748http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/510/1748GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/510/1748/table4 ({delta} Scuti stars pulsating in four radial modes simultaneously)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/510/1748/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/510/1748/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/510/1748/table4?GETtext/xml+votable180.050000true263.3875-26.81563890.005555555555555556Cone search capability for table J/MNRAS/510/1748/tablea1 ({delta} Scuti stars classified as pulsating in three radial modes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/510/1748/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/510/1748/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/510/1748/tablea1?GETtext/xml+votable180.050000true258.3465833-29.82858330.0055555555555555564/1795 5/7175 7177 7179 7192 7194-7195 7205 7216-7217 7220 6/28687 28696 28699 28705-28707 28713 28715 28747 28772 28774-28775 28784 28786-28787 28794-28796 28800 28804 28816-28817 28829 28839 28843-28844 28847 28854 28857-28860 28862 28872-28873 28877 28884 28886-28887 28893 28906-28910 28922 29058 29065-29066 29184-29185 29248-29249 29251-29252 29254-29256 29261 29265-29266 29272-29273 42495 42837 48036 48040-48041https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/510/1748?format=asciiOpticaldefaultJ/MNRAS/510/1748/table4{delta} Scuti stars pulsating in four radial modes simultaneouslyrecnoRecord number assigned by the VizieR team.
