Horizontal Branch Morphology and Mass Loss in Globular Clusters

The connection between mass loss on the red giant branch (RGB) and horizontal branch (HB) morphology in globular clusters (GCs) has long been acknowledged but the mechanisms governing mass loss remains poorly understood from a theoretical perspective. The present study uses synthetic HB models to demonstrate for the first time that α-enhancement and a simple relation between mass loss and metal...

Mass Loss from Globular Clusters

We consider both observational and theoretical issues related to dynamical mass loss from the old globular star clusters of the Galaxy. On the observational side the evidence includes tidal tails and extratidal extensions, kinematic effects, effects on the mass function, and influences on the statistical properties of surviving objects. Even for isolated clusters, the theoretical issues are not...

The 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...

The role of super-asymptotic giant branch ejecta in the abundance patterns of multiple populations in globular clusters

Star formation from matter including the hot CNO processed ejecta of asymptotic giant branch (AGB) winds is regarded as a plausible scenario to account for the chemical composition of a stellar second generation (SG) in globular clusters. The chemical evolution models, based on this hypothesis, so far included only the yields available for the massive AGB stars, while the possible role of super...

Evolution of the dust mass loss with luminosity along the giant branch of the globular cluster 47 Tuc

ASTRONOMY AND ASTROPHYSICS Evolution of the dust mass loss with luminosity along the giant branch of the globular cluster 47 Tuc Abstract. The present paper investigates the properties of the dust mass loss in stars populating the giant branch of the globular cluster 47 Tuc, by combining ISOCAM and DENIS data. Raster maps of 5 fields covering areas ranging from 4 × 4 to 15 × 15 arcmin 2 at diff...
