cds-question@unistra.fropen-star-clustersvisible-astronomybroad-band-photometryproper-motionstrigonometric-parallaxA detailed analysis of ground-based CCD UBV photometry and space-based Gaia Data Release 3 (DR3) data for the open clusters King-6 and NGC-1605 was performed. Using the pyUPMASK algorithm on Gaia astrometric data to estimate cluster membership probabilities, we have identified 112 stars in King 6 and 160 stars in NGC-1605 as the statistically most likely members of each cluster. We calculated reddening and metallicity separately using UBV two-color diagrams to estimate parameter values via independent methods. The color excess E(B-V) and photometric metallicity [Fe/H] for King-6 are 0.515{+/-}0.030mag and 0.02{+/-}0.20dex, respectively. For NGC-1605, they are 0.840{+/-}0.054mag and 0.01{+/-}0.20dex, respectively. With reddening and metallicity kept constant, we have estimated the distances and cluster ages by fitting PARSEC isochrones to color-magnitude diagrams based on the Gaia and UBV data. The photometric distances are 723{+/-}34pc for King-6 and 3054{+/-}243pc for NGC-1605. The cluster ages are 200{+/-}20Myr and 400{+/-}50 Myr for King-6 and NGC-1605, respectively. The mass function slopes were found to be 1.29{+/-}0.18 and 1.63{+/-}0.36 for King-6 and NGC-1605, respectively. These values are in good agreement with the value of Salpeter. The relaxation times were estimated as 5.8Myr for King-6 and60 Myr for NGC-1605. These indicate that both clusters are dynamically relaxed since these times are less than the estimated cluster ages. A Galactic orbit analysis shows that both clusters formed outside the solar circle and are members of the young thin-disk population.2023AJ....166..263Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/166/263CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)I/350 : Gaia EDR3 (Gaia Collaboration, 2020)V/164 : LAMOST DR5 catalogs (Luo+, 2019)J/A+AS/109/375 : Blue stragglers in open clusters (Ahumada+, 1995)J/A+AS/133/387 : NGC 1817 and NGC 1807 proper motions (Balaguer-Nunnez+ 1998)J/AJ/115/592 : VI photometry of NGC 2157 (Fischer+, 1998)J/A+A/329/101 : Masses of Pleiades members (Raboud+ 1998)J/A+AS/141/491 : Chemical composition of halo and disk stars (Nissen+, 2000)J/A+A/438/1163 : Catalogue of Open Cluster Data (COCD) (Kharchenko+, 2005)J/AJ/131/1184 : Recalibration of optical photometry (Maiz-Apellaniz+, 2006)J/AJ/137/4186 : UBVRI standards around celestial equator (Landolt, 2009)J/AJ/141/92 : BVI photometry of 10 distant open clusters (Janes+, 2011)J/A+A/543/A156 : Milky Way global survey of star clusters (Kharchenko+, 2012)J/ApJ/764/73 : HST VI photometry of HD 97950 cluster members (Pang+, 2013)J/MNRAS/430/3350 : Proper motions and membership in NGC 3766 (Yadav+, 2013)J/AJ/147/139 : UBVRI CCD photo open clusters.
