cds-question@unistra.fropen-star-clustersvariable-starsinfrared-photometryvisible-astronomybroad-band-photometryWe present a multiyear survey aimed at collecting (1) high-precision (~5 milli-mag), (2) fast-cadence (~3-min), and (3) relatively long duration (~10d) multiband photometric series. The goal of the survey is to discover and characterize efficiently variable objects and exoplanetary transits in four fields containing five nearby open clusters spanning a broad range of ages. More in detail, our project will (1) constitute a preparatory survey for the High Accuracy Radial velocity Planet Searcher for the Northern hemisphere (HARPS-N) mounted at the Telescopio Nazionale Galileo (TNG), which will be used for spectroscopic follow-up of any target of interest that this survey discovers or characterizes, (2) measure rotational periods and estimate the activity level of targets we are already monitoring with HARPS and HARPS-N for exoplanet transit search, and (3) long-term characterization of selected targets of interest in open clusters within the planned K2 fields. In this first paper, we give an overview of the project, and report on the variability of objects within the first of our selected fields, which contains two open clusters: M35 and NGC 2158. We detect 519 variable objects, 273 of which are new discoveries, while the periods of most of the previously known variables are considerably improved.2015MNRAS.447.3536Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/447/3536CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/564/A79 : Proper motions of open clusters from UCAC4 (Dias+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/447/3536https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/447/3536http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/447/3536https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/447/3536https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/447/3536http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/447/3536GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/447/3536/variable (Catalogue of variable stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/447/3536/variable?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/447/3536/variable?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/447/3536/variable?GETtext/xml+votable180.050000true91.8584219424.073243060.005555555555555556Cone search capability for table J/MNRAS/447/3536/m35n2158 (M35 and NGC2158 field astro-photometric catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/447/3536/m35n2158?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/447/3536/m35n2158?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/447/3536/m35n2158?GETtext/xml+votable180.050000true92.5488323.92155690.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/MNRAS/447/35366/24338-24339 24344-243458.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/447/3536?format=asciiOpticalInfrareddefaultJ/MNRAS/447/3536/variableCatalogue of variable starsID[1/519] ID number of the starmeta.id;meta.mainintHu05Variable ID in Hu et al.
