Segregation 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 کاملTidal Stream Associated with the Globular Cluster NGC
We report on the detection in Sloan Digital Sky Survey data of a 45 • tidal stream of stars, extending from Bootes to Ursa Major, which we associate with the halo globular cluster NGC 5466. Using an optimal contrast, matched filter technique, we find a long, almost linear stellar stream with an average width of 1.4 •. The stream is an order of magnitude more tenuous than the stream associated w...
متن کاملThe 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 کاملVariable Stars in the Field of the Globular Cluster Ngc
We report on the discovery and analysis of 14 short-period variable stars in the field of the southern globular cluster NGC 3201, located within roughly two magnitudes on either side of the main-sequence turnoff. 11 of these variable stars are eclipsing binaries, one is an RR Lyrae, and two are thus far unclassified systems. Among the eclipsing binary stars, nine are of the W Ursa Majoris (W UM...
متن کاملThe globular cluster NGC 1978 in the Large Magellanic Cloud
We have used deep high-resolution Hubble Space Telescope ACS observations to image the cluster NGC 1978 in the Large Magellanic Cloud. This high-quality photometric data set allowed us to confirm the high ellipticity (ǫ ∼0.30±0.02) of this stellar system. The derived Color Magnitude Diagram allowed a detailed study of the main evolutionary sequences: in particular we have detected the so called...
