cds-question@unistra.frmilky-way-galaxynovaeapparent-magnitudeWe report the discovery of forty erupting cataclysmic variable stars in the OGLE-III Galactic disk fields: seventeen objects of U Gem type, four of Z Cam type, and nineteen stars showing outbursts and superoutbursts typical for SU UMa type dwarf novae. In the case of five stars we were able to estimate their supercycle lengths. The obtained lengths are in the range of 20-90 d, generally between the typical SU UMa type variables and a few objects classified as the ER UMa type variables. Since there is no significant difference between the two types but a higher mass-transfer rate resulting in more frequent outbursts and superoutbursts in the ER UMa type stars, we propose to discard this type as a separate class of variables. We note that in one of the SU UMa type stars, OGLE-GD-DN-039, we found a negative supercycle period change, in contrast to other active systems of this type. Two of the new OGLE objects showed long-duration WZ Sge-like superoutbursts followed by a sequence of echo outbursts. All stars reported in this paper are part of the OGLE-III Catalog of Variable Stars.2013AcA....63..135Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/63/135CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/65/313 : One thousand new dwarf novae from the OGLE Survey (Mroz+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/63/135https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/63/135http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/63/135https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/63/135https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/63/135http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/63/135GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/63/135/table1 (Basic data on the discovered DNe in the OGLE-III disk fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/63/135/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/63/135/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/63/135/table1?GETtext/xml+votable180.050000true159.0824167-63.62577780.0055555555555555566/37245-37247 37317 37328-37329 37332 37905 37923 37928 37930 41623 41629-41630 41666https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/63/135?format=asciidefaultJ/AcA/63/135/table1Basic data on the discovered DNe in the OGLE-III disk fieldsrecnoRecord number assigned by the VizieR team.
