Telescope Study of the Globular Cluster Ngc 288
We report on the Chandra X-ray Observatory observations of the globular cluster NGC 288. We detect four X-ray sources within the core radius and seven additional sources within the half-mass radius down to a limiting luminosity of LX = 7×1030 ergs s−1 (assuming cluster membership) in the 0.3–7 keV band. We also observed the cluster with the Hubble Space Telescope Advanced Camera for Surveys and...
متن کاملRed giant depletion in globular cluster cores
We investigate the observed depletion of red giants in the cores of post-core-collapse globular clusters. In particular, the evolutionary scenario we consider is a binary consisting of two lowmass stars which undergoes two common-envelope phases. The first common-envelope phase occurs when the primary is a red giant resulting in a helium white dwarf and main-sequence star in a detached binary. ...
متن کاملAbundances in giant stars of the globular cluster NGC 6752 ⋆
Recent theoretical yields and chemical evolution models demonstrate that intermediate-mass AGB stars cannot reproduce the observed abundance distributions of O, Na, Mg, and Al. As a further observational test of this finding, we present elemental abundance ratios [X/Fe] for 20 elements in 38 bright giants of the globular cluster NGC 6752 based on high-resolution, high signal-to-noise spectra ob...
متن کاملProton-Capture Nucleosynthesis in Globular Cluster Red Giant Stars
Observational evidence suggests that many of the variations of the surface abundances of light to intermediate mass elements (A < 28) in globular cluster red-giant-branch (RGB) stars can be attributed to non-canonical mixing between the surface and the deep stellar interior during the RGB phase. As a first step to studying this mixing in more detail, we have combined a large nuclear reaction ne...
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...
