ASTRONOMY AND ASTROPHYSICS Colour - magnitude diagrams of the inner halo globular clusters NGC 5986 and NGC 6712 ?
We present V and I photometry for NGC 5986 and B and V for NGC 6712. NGC 5986 has a blue extended horizontal branch, while NGC 6712 has a composite red and blue horizontal branch, where the latter extends to unusual bluer colours. Both clusters have RR Lyrae. We derive a reddening E(B-V) ≈ 0.29 and a distance from the Sun d ≈ 11.2 kpc for NGC 5986, and E(B-V) ≈ 0.33 and d ≈ 7.9 kpc for NGC 6712...
متن کاملChemical Abundances of Three Metal-poor Globular Clusters (ngc 6287, Ngc 6293, and Ngc 6541) in the Inner Halo
We present a chemical abundance study of three inner old halo clusters NGC 6287, NGC 6293, and NGC 6541, finding [Fe/H] = −2.01 ± 0.05, −1.99 ± 0.02, and −1.76 ± 0.02 (internal), respectively, and our metallicity measurements are in good agreement with previous estimates. We also present the radial velocity measurements of the clusters. Our radial velocity measurements for NGC 6293 and NGC 6541...
متن کاملGlobular clusters in NGC 5128 ?
We used the Wide Field Planetary Camera 2 aboard the Hubble Space Telescope to search for globular clusters in the inner regions of the nearby giant elliptical galaxy NGC 5128. This galaxy is believed to be the product of a merger between a large elliptical galaxy and a small late-type spiral between 160 and 500 Myr ago. We identified 21 globular cluster candidates and measured their core radii...
متن کاملThe Chemical Composition of Red Giant Branch Stars in the Galactic Globular Clusters Ngc
We present radial velocities and chemical abundances for red giant branch stars in the Galactic bulge globular clusters NGC 6342 and NGC 6366. The velocities and abundances are based on measurements of high resolution (R & 20,000) spectra obtained with the MMT–Hectochelle and WIYN–Hydra spectrographs. We find that NGC 6342 has a heliocentric radial velocity of +112.5 km s (σ = 8.6 km s), NGC 63...
متن کاملHalo Surrounding the Galactic Globular Ngc 1851
Using imaging that shows four magnitudes of main sequence stars, we have discovered that the Galactic globular cluster NGC 1851 is surrounded by a halo that is visible from the tidal radius of 700 arcsec (41 pc) to more than 4500 arcsec (>250 pc). This halo is symmetric and falls in density as a power law of r. It contains approximately 0.1% of the dynamical mass of NGC 1851. There is no eviden...
