Two of them are quite young and follow the trace of the Carina Arm and the already detected warp. The results of the mag are used to build CMDs, radial density profiles, colour-colour We also focus We aim to update the Gaia DR2 cluster census by performing membership determinations for known clusters that had been missed by previous studies and for recently-discovered clusters. estimated. PDF | A sample of 145 JHK--2MASS observations of NGC open star clusters is studied, of which 132 have never been studied before. The comparison of distances from photometry and parallaxes data in turn reveals a variable level of disagreement. We investigate a sub-set of non-detected clusters that, according to their literature parameters, should be easily visible in Gaia . In general, our results are consistent with those derived by other methods, We present the fundamental parameters of ten open star clusters, nominated from Kronberger et al.

The fitting errors are ∼ ±0.10 mag in distance modulus, and ∼ ±0.05 mag in color excess. All rights reserved. Also, the main Conclusions. The NGC Catalog is a curated set of GPU-optimized software.It consists of containers, pre-trained models, Helm charts for Kubernetes deployments and industry specific AI toolkits with software development kits (SDKs). It is likely that the objects discussed in this study only represent a fraction of the non-physical groupings erroneously listed in the catalogues as genuine open clusters and that those lists need further cleaning. The origin of this discrepancy is likely linked to the brighter polycyclic aromatic hydrocarbon emission observed toward HD 100546. Also, the main photometric parameters (age, distance modulus, color excesses, Trumpler~22 and Lynga~6 are included in our study because they are widely known, and thus provided a check of our data and methodology. Vertically on the galactic disk, within about 800 pc, the metallicity gradient is found to be so trivial. Total

We present a study of the old open cluster Trumpler 5 (Tr 5), based on the CDS archival data.

Recent publications making use of Gaia DR2 data have provided membership lists for over a thousand clusters, however, many nearby objects listed in the literature have so far evaded detection.

Methods. This paper has two main objectives: (1) To determine the intrinsic properties of 16 faint and mostly unstudied open clusters in the poorly known sector of the Galaxy at 270° −300° to probe the Milky Way structure in future investigations. Using the DIRBE 100 and 240 μm data, we have constructed a map of the dust temperature so that the 100 μm map may be converted to a map proportional to dust column density. (2) To address previously reported systematics in Gaia DR2 parallaxes by comparing the cluster distances derived from photometry with those derived from parallaxes. Results. An example for the lower radius determination for NGC 1498, the curved line represents the fitting of King (1962) model. From field stars of similar metallicity, the Hyades ([Fe/H] = +0.13) with no reddening has (m-M)_0 = 3.33 +/- 0.02 and M67, with E(B-V) = 0.041, A_V = 3.1E(B-V), and [Fe/H] = 0.00, has (m-M)_0 = 9.71 +/- 0.02 (s.e.m), where the errors quoted refer to internal errors alone.
