cds-question@unistra.frvariable-starsphotometryWe present investigation of V=17mag star, which appears to be SX Phe type variable. Observations at 1.8 and 1.0 meter telescopes of Boyhunsan and Mount Lemon observatories permit us to improve the light elements and to investigate the power spectrum. We applied a Fourier decomposition to the data in order to determine the component frequencies of the synthetic light curve, and five components including a pair of closely separated components of f_1_=24.6539 and f_2_=24.8173 c/d were identified. We proposed that one of these two components corresponds to a non-radial oscillation mode. Other observed frequencies are the combinations of the first two. Metallicity of the star was estimated to be [Fe/H]<-2. We also found that one of the faint variable stars, No. 14, in the field is RRc type pulsator.2007AZh....84..695Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/84/695CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/84/695https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/84/695http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/84/695https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/84/695https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/84/695http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/84/695GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AZh/84/695/table1Observations of 2-7-0122 (P=0.04056150)recnoRecord number assigned by the VizieR team.
