We collected photometric time-series data on 14 white dwarf variable candidates at Konkoly Observatory, and found two new bright ZZ Ceti stars, namely EGGR 120 and WD 1310+583. We performed a Fourier analysis of the datasets. In the case of EGGR 120, which was observed on one night only, we found one significant frequency at 1332uHz with 2.3mmag amplitude. We successfully observed WD 1310+583 on eight nights, and determined 17 significant frequencies in the whole dataset. Seven of them seem to be independent pulsation modes between 634 and 2740uHz, and we performed preliminary asteroseismic investigations of the star utilizing six of these periods. We also identified three new light variables on the fields of white dwarf candidates: an eclipsing binary, a candidate delta Scuti/beta Cephei and a candidate W UMa-type star.2018MNRAS.478.2676Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/478/2676CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/478/2676https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/478/2676http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/478/2676https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/478/2676https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/478/2676http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/478/2676GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/478/2676/stars (*List of studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/478/2676/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/478/2676/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/478/2676/stars?GETtext/xml+votable180.050000true242.092458342.09538890.0055555555555555566/469 1088 2068 2832 3313 3393 8510 9424 9840 11131 17846 20404 23924 27395https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/478/2676?format=asciidefaultJ/MNRAS/478/2676/stars*List of studied starsrecnoRecord number assigned by the VizieR team.
