cds-question@unistra.frwhite-dwarf-starsphotometryWe report the effort to search for white dwarf p-mode oscillations in RX J2117.1+3412 (V2027 Cyg), a GW Vir star. The data were taken with Miosotys, a multi-fiber photometer, mounted on the 1.93-m telescope at Observatoire de Haute-Provence (OHP) with a 20-Hz cadence in May 2010 and June 2012. Two intriguing signatures at 1.2081Hz and 2.5852Hz were found at 3.8{sigma} and 3.5{sigma} significance levels, respectively. However, possible atmospheric effects cannot be ruled out. If these two features are not real, the 3{sigma} upper limit of the relative amplitude for the possible oscillations in the frequency range from 1 to 10Hz is estimated to be about 6x10^-4^. This is the first report in the literature for a p-mode oscillation search of GW Vir stars.2013A&A...558A..63Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/558/A63CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/558/A63https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/558/A63http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/558/A63https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/558/A63https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/558/A63http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/558/A63GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/558/A63/0524tV2027 Cyg light curve on May 24, 2010recnoRecord number assigned by the VizieR team.
