The Discovery of Tidal Tails around the Globular Cluster Ngc 5466
We report the discovery of tidal tails around the high-latitude Galactic globular cluster NGC 5466 in Sloan Digital Sky Survey (SDSS) data. Neural networks are used to reconstruct the probability distribution of cluster stars in u, g, r, i, z space. The tails are clearly visible, once extra-galactic contaminants and field stars have been eliminated. They extend ∼ 4 • on the sky, corresponding t...
متن کاملSegregation and Tidal Tails of the Globular Cluster NGC 7492
We present a wide field CCD photometric study of Galactic globular cluster NGC 7492. The derived V R color-magnitude diagram extends down to about 3.5 mag below the cluster main sequence turn-off. The field covers 42 × 42 about 3 times larger than the known tidal radius of this cluster. The sample of cluster member candidates obtained by CMD-mask process has been used to construct luminosity an...
متن کاملOld open clusters : UBGVRI photometry of NGC 2506 ⋆
UBGVRI photometry for the open cluster NGC 2506 is presented. From comparison of the observed colour-magnitude diagrams with simulations based on stellar evolutionary models we derive in a self consistent way reddening, distance, and age of the cluster: E(B−V)=0-0.07, (m-M)0 = 12.6±0.1, τ = 1.5-2.2 Gyr. The cluster shows a well definite secondary sequence, suggesting that binary systems constit...
متن کاملOscillating Blue Stragglers , γ Doradus stars and eclipsing binaries in the open cluster NGC 2506 ⋆
Context. This is the first step in a project to combine studies of eclipsing binaries and oscillating stars to probe the interior of Blue Stragglers (BS). This may imply a way to discriminate observationally between different birth mechanisms of BS stars. Aims. We study the open cluster NGC2506 which contains oscillating BS stars and detached eclipsing binaries for which accurate parameters can...
متن کاملUBVRI CCD photometry of the old open cluster NGC 6253 ⋆
We present UBVRI photometry for the old open cluster NGC 6253. From comparison of the observed colour-magnitude diagrams with simulations based on stellar evolutionary models we derive in a self consistent way reddening, distance, and age of the cluster: E(B−V)= 0.23–0.32, (m-M)0 = 10.9±0.1, metallicity roughly double than solar, and age ≃ 3 Gyr. The cluster has a binary sequence, discernible e...
