In this study, we used the most numerous sample of HADS from the OGLE inner bulge fields that likely pulsate in either three or four radial modes simultaneously. We have computed a grid of pulsation models along evolutionary tracks and determined the physical parameters of stars by matching their pulsation periods and period ratios. For 176 HADS, we determined physical parameters, i.e. masses, luminosities, effective temperatures, metallicities, and ages. We present the distribution of physical parameters and discuss their properties. We selected 16 candidates for SX Phoenicis stars.2022MNRAS.515.4574Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/515/4574CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/490/4040 : {delta} Scuti and {gamma} Doradus stars in TESSJ/MNRAS/485/2380 : Gaia-derived luminosities of Kepler A/F stars (Murphy+,2019)J/MNRAS/466/1290 : Metal-rich SX Phe stars in Kepler field (Nemec+, 2017)J/MNRAS/510/1748 : {delta} Scuti variable stars with OGLE-IV (Netzel+, 2022)J/A+AS/144/469 : Delta Scuti stars (Rodriguez+, 2000)J/AcA/63/379 : OGLE-III variable stars in Galactic disk areaJ/AcA/60/1 : VI light curves of LMC delta Scuti stars (Poleski+, 2010)I/352 : Distances to 1.47 billion stars in Gaia EDR3I/350 : Gaia EDR3 (Gaia Collaboration, 2020)I/337 : Gaia DR1 (Gaia Collaboration, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/515/4574https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/515/4574http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/515/4574https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/515/4574https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/515/4574http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/515/4574GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/515/4574/table1 (Observed and calculated periods and ratios for high-amplitude {delta} Scuti stars HADS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/515/4574/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/515/4574/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/515/4574/table1?GETtext/xml+votable180.050000true258.3882083-29.39619440.0055555555555555565/7180 7183 7194-7195 7205 7216-7217 7220 6/28701 28705 28707 28709-28711 28713 28715 28717 28719 28724 28726-28729 28731 28768 28770-28771 28774-28775 28784 28786 28794-28795 28800 28804 28816-28817 28844 28854 28857-28858 28860 28872-28873 28877 28884 28893 28907-28910 28922 29184 29256 29261 29272 48036 48041https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/515/4574?format=asciiOpticaldefaultJ/MNRAS/515/4574/table1Observed and calculated periods and ratios for high-amplitude {delta} Scuti stars HADSrecnoRecord number assigned by the VizieR team.
