It was also shown that strong UV radiation emitted by nearby massive stars can heat a circumstellar disk up to some thousand degrees, inducing the photoevaporation of the gas. This process strongly reduces the dissipation time scale. We study whether there exists a correlation between the spatial distribution of stars with circumstellar disks and the position of massive stars with spectral class earlier than B5, in the open cluster NGC 6611. We created a multiband catalog of the cluster, down to V~23mag, using optical data from a WFI observation at 2.2m of ESO in the BVI bands, the 2MASS public point source catalog and an archival X-ray observation made with CHANDRA/ACIS. We selected the stars with infrared excess (due to the emission of a circumstellar disk) using suitable color indices independent of extinction, and studied their spatial distribution.2007A&A...462..245Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/462/245CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/A+AS/134/525 : NGC 6611 compiled catalog (Belikov+ 1999)J/AJ/106/1906 : NGC 6611: A Cluster Caught in the Act (Hillenbrand+ 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/462/245https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/462/245http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/462/245https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/462/245https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/462/245http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/462/245GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/462/245/catalog (Electronic multiband catalog (full catalog + 148 X-ray sources without optical or 2MASS counterpart))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/462/245/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/462/245/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/462/245/catalog?GETtext/xml+votable180.050000true274.91314694-13.760506940.0055555555555555566/29461 29463 29504 295068.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/462/245?format=asciiOpticalInfrareddefaultJ/A+A/462/245/catalogElectronic multiband catalog (full catalog + 148 X-ray sources without optical or 2MASS counterpart)recnoRecord number assigned by the VizieR team.
