The Metal Content of the Bulge Globular Cluster NGC 6528 ⋆
High resolution spectra of five stars in the bulge globular cluster NGC 6528 were obtained at the 8m VLT UT2-Kueyen telescope with the UVES spectrograph. Out of the five stars, two of them showed evidence of binarity. The target stars belong to the horizontal and red giant branch stages, at 4000 < Teff < 4800 K. Multiband V, I, J,H,Ks photometry was used to derive initial effective temperatures...
متن کاملNa - O Anticorrelation and HB . VI . The chemical composition of the peculiar bulge globular cluster NGC 6388 ⋆
We present the LTE abundance analysis of high resolution spectra for red giant stars in the peculiar bulge globular cluster NGC 6388. Spectra of seven members were taken using the UVES spectrograph at the ESO VLT2 and the multiobject FLAMES facility. We exclude any intrinsic metallicity spread in this cluster: on average, [Fe/H]= −0.44 ± 0.01 ± 0.03 dex on the scale of the present series of pap...
متن کاملNear - Infrared photometry of four metal - rich Bulge globular clusters : NGC 6304 , NGC 6569 , NGC 6637 , NGC 6638 ⋆
We present high-quality near-Infrared photometry of four Bulge metal-rich globular clusters, namely: NGC 6304, NGC 6569, NGC 6637 and NGC 6638. By using the observed Colour-Magnitude Diagrams we derived a photometric estimates of the cluster reddening and distance. We performed a detailed analysis of the Red Giant Branch, presenting a complete description of morphologic parameters and evolution...
متن کاملObservations of Galactic Globular Cluster Cores . II . NGC 6273 and the Problem of Horizontal - Branch Gaps
We present observations of the center of the Galactic globular cluster NGC 6273, obtained with the HST/WFPC2 camera as part of the snapshot program GO-7470. A B, V color–magnitude diagram (CMD) for ∼28,000 stars is presented and discussed. The most prominent feature of the CMD, identified for the first time in this paper, is the extended horizontal branch blue tail (EBT) with a clear double-pea...
متن کاملConstraints on Helium Enhancement in the Globular Cluster M3 (ngc 5272): the Horizontal Branch Test
It has recently been suggested that the presence of multiple populations showing various amounts of helium enhancement is the rule, rather than the exception, among globular star clusters. An important prediction of this helium enhancement scenario is that the helium-enhanced blue horizontal branch (HB) stars should be brighter than the red HB stars which are not helium-enhanced. In this Letter...
