NGC 6404 and NGC 6583 : two neglected intermediate - age open clusters located in the Galactic Center direction
We report on V I CCD photometry of two fields centered in the region of the open clusters NGC 6404 and NGC 6583 down to V = 22.0. These clusters have never been studied insofar, and we provide for the first time estimates of their fundamental parameters, namely, radial extent, age, distance and reddening. We find that NGC 6404 radius is 2.0 arcmin, as previously proposed, while NGC 6583 radius ...
متن کاملAstrophysical Parameters of Galactic Open Clusters
We present a catalogue of astrophysical data of 520 Galactic open clusters. These are the clusters, for which at least three most probable members (18 on average) could be identified in the ASCC-2.5, a catalogue of stars based on the Tycho-2 observations from the Hipparcos mission. We applied homogeneous methods and algorithms to determine angular sizes of cluster cores and coronae, heliocentri...
متن کاملNGC 1245 - an intermediate age open cluster
The B,V CCD photometry of 916 stars in the field of the high galactic latitude intermediate age open cluster NGC 1245 is presented. The cluster parameters were estimated with the help of V vs (B−V) colour magnitude diagram (CMD). After correcting for intra-cluster reddening, the mean redding towards the cluster was found to be 0.29±0.05 mag, with a distance modulus (m−M)0 equal to 12.4±0.3 mag....
متن کاملThe intermediate age open cluster NGC 2660 ⋆
We present CCD UBVI photometry of the intermediate old open cluster NGC2660, covering from the red giants region to about seven magnitudes below the main sequence turn-off. Using the synthetic Colour Magnitude Diagram method, we estimate in a selfconsistent way values for distance modulus ((m-M)0≃ 12.2), reddening (E(B − V ) ≃ 0.40), metallicity ([Fe/H] about solar), and age (τ ∼ < 1 Gyr). A 30...
متن کاملNear - infrared photometry of the intermediate age open clusters IC 166 and NGC 7789 ?
We present and discuss new photometric data obtained with an IR camera in the J and K pass-bands for the intermediate age open clusters IC 166 (936 stars in total) and NGC 7789 (1030 stars in total). IC 166 is a poorly studied open cluster for which no IR data was available previously, while NGC 7789 is a well studied open cluster. We show that IC 166 is of intermediate age (about 1.0 Gyr), wit...
