cds-question@unistra.frvariable-starsphotometryV2492 Cyg is a young eruptive star that went into outburst in 2010. The near-infrared color changes observed since the outburst peak suggest that the source belongs to a newly defined sub-class of young eruptive stars, where time-dependent accretion and variable line-of-sight extinction play a combined role in the flux changes. In order to learn about the origin of the light variations and to explore the circumstellar and interstellar environment of V2492 Cyg, we monitored the source at ten different wavelengths, between 0.55um and 2.2um from the ground and between 3.6um and 160um from space. We analyze the light curves and study the color-color diagrams via comparison with the standard reddening path. We examine the structure of the molecular cloud hosting V2492 Cyg by computing temperature and optical depth maps from the far-infrared data.2013A&A...551A..62Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/551/A62CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/551/A62https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/551/A62http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/551/A62https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/551/A62https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/551/A62http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/551/A62GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap7.952274030004205e-20 3.852589004194616e-19OpticaldefaultJ/A+A/551/A62/table1Optical and near-infrared photometry for V2492 CygTelTelescope (1)meta.id;instr.telcharrecnoRecord number assigned by the VizieR team.
