It has been suggested that the anomalous abundances of Na, Mg and Al observed in globular cluster red giant stars could be the result of a thermally unstable hydrogen shell. Currently accepted reaction rates indicate that temperatures of approximately 70-75 × 10 6 K are required to produce the observed enhancements in Na and Al along with depletions in Mg. The work presented here attempts to model the H shell instability by a simple mechanism of altering the energy production in the region of… 

Thermal Stability of Rotating Low-Mass Subgiants and Red Giants

A linear analysis of the thermal stability of rotating low-mass stars evolving from the zero-age main sequence (ZAMS) to the red giant branch (RGB) tip has been carried out. Two stellar models are

Chemical Compositions of Red Giant Stars in Old Large Magellanic Cloud Globular Clusters

We have observed 10 red giant stars in four old Large Magellanic Cloud globular clusters with the high-resolution spectrograph MIKE on the Magellan Landon Clay 6.5 m telescope. The stars in our

Mg isotopic ratios in giant stars of the globular cluster NGC 6752

Mg isotopic abundance ratios are measured in 20 bright red giants in globular cluster NGC 6752 based on very high-resolution (R 110 000), high signal-to-noise spectra obtained with UVES on the VLT.

Carbon abundances and 12C/13C from globular cluster giants --

The behaviour of the Δν = 2 CO bands around 2.3 μm was examined by comparing observed and synthetic spectra in stars in globular clusters of different metallicity. Changes in the 1 2 C/ 1 3 C

CN Abundance Inhomogeneities in the Globular Cluster Messier 4 (NGC 6121): Results Based on Merged Data Sets from the Literature

In this paper, we investigate the behavior of the λ3883 CN absorption bands in the spectra of red giants in the globular cluster Messier 4. Data from three literature sources, including the original




The most recent observations of the abundances of oxygen, sodium, magnesium, and aluminum provide strong support for the idea that "deep mixing" occurs within M13 giants. In deep mixing scenarios,

Meridional circulation and CNO anomalies in red giant stars

The possibility that meridional circulation due to internal rotation might lead to the mixing of CNO-processed material from the vicinity of the hydrogen shell into the envelope of a red giant star

Lambda-3883 CN Band Strengths for 238 Metal-Poor Halo Giants: Evidence for Chemical Differences between Globular Cluster and Halo Field Giants

Cyanogen band strengths mCN for 238 metal-poor giants in the halo field and in 13 globular clusters are tabulated. The distribution of mCN in field giants of intermediate metallicity is compared with

Massive Thorne–Żytkow objects: structure and nucleosynthesis

The structure of stars with massive envelopes (M env ≥14 M ○ .) and degenerate neutron cores is discussed. In such stars, most of the luminosity arises from thermonuclear reactions taking place at

Correlated cyanogen and sodium anomalies in the globular clusters 47 Tuc and NGC 6752

Spectroscopic analyses have been made of echelle plates of pairs of CN-strong and CN-weak giants in the globular clusters 47 Tuc and NGC 6752. Our differential analysis reveals that in NGC 6752

Cyanogen strengths of globular cluster post-main-sequence stars

CN strengths in the peculiar clusters Cen and M22 and the metal-rich clusters 47 Tuc, M71, and NGC 6352 are found to vary markedly from star to star. The strong variations in CN strength
