cds-question@unistra.fropen-star-clustersccd-photometryvisible-astronomymedium-band-photometryBy studying young open clusters, the mechanisms important for star formation over several Myr can be examined. For example, accretion rate as a function of rotational velocity can be investigated. Similarly, sequential star formation triggered by massive stars with high mass-loss rates can be studied in detail. We identified and characterized probable members of NGC 6383, as well as determined cluster parameters. New Stromgren uvby CCD photometry, obtained by us, is presented. This new data, together with Johnson UBV and 2MASS data in the NIR, was used to investigate characteristics of pre- as well as zero age main sequence cluster members. We present Stromgren uvby CCD photometry for 272 stars in the field of NGC 6383 and derive its reddening, E(b-y)=0.21(4)mag, as well as distance, d=1.7(3)kpc from the Sun. Several stars with NIR excess and objects in the domain of the classical Herbig Ae/Be and T Tauri stars were detected. Two previously known variables were identified as rapidly-rotating PMS stars. The field population is clearly separated from the probable members in the color-magnitude diagram. NGC 6383 is a young open cluster, with an age of less than 4Myr, undergoing continuous star formation. True pre-main sequence members might be found down to absolute magnitudes of +6mag, with a variety of rotational velocities and stellar activities.2007A&A...462..157Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/462/157CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/357/345 : Pulsating pre-main-sequence stars in NGC6383 (Zintz+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/462/157https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/462/157http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/462/157https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/462/157https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/462/157http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/462/157GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/462/157/table1 (Observed program stars of NGC 6383)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/462/157/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/462/157/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/462/157/table1?GETtext/xml+votable180.050000true263.8194389-32.62887690.0055555555555555566/288098.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/462/157?format=asciiOpticaldefaultJ/A+A/462/157/table1Observed program stars of NGC 6383recnoRecord number assigned by the VizieR team.
