It has been known for a long time that some red giants in globular clusters exhibit large star-to-star variations in the abundances of light elements that are not exhibited by field giants. This fact can be taken as evidence that the extra mixing mechanism(s) that operate in globular cluster giants may be consequences of star-star interactions in the dense stellar environment. In order to constrain the extra mixing mechanism(s), we study the influence of helium enrichment along the red giant… Expand
Tidal Interactions of Red Giants with Environment Stars in Globular Clusters
We investigate the tidal interactions of a red giant with a main-sequence star in the dense stellar core of globular clusters by the smoothed particle hydrodynamics method. Two models of -->0.8 M☉Expand
Overluminous Blue Horizontal-Branch Stars Formed by Low-Mass Companions
We construct a speculative scenario for rotation-induced extra helium mixing to the envelope of horizontal-branch (HB) stars. This scenario differs from previous ones in that the mixing occurs afterExpand
HIGHLY He-RICH MATTER DREDGED UP BY EXTRA MIXING THROUGH STELLAR ENCOUNTERS IN GLOBULAR CLUSTERS
The unveiled main-sequence splitting in ω Centauri as well as NGC 2808 suggests that matter highly enriched in He (in terms of its mass fraction Y ~ 0.4) was produced and made the color of someExpand
Surface Pollution of Main-Sequence Stars through Encounters with AGB Ejecta in ω Centauri
The origin of a double main sequence (MS) in ω Centauri is explored. We have shown from theoretical calculations of stellar evolution that the colors of MS stars are shifted to those of the observedExpand
Carbon Abundance Inhomogeneities and Deep Mixing Rates in Galactic Globular Clusters
Among stars in Galactic globular clusters the carbon abundance tends to decrease with increasing luminosity on the upper red giant branch, particularly within the lowest metallicity clusters. WhileExpand
Horizontal branch stars: the interplay between observations and theory, and insights into the formation of the Galaxy
We review and discuss horizontal branch (HB) stars in a broad astrophysical context, including both variable and non-variable stars. A reassessment of the Oosterhoff dichotomy is presented, whichExpand
The peculiar horizontal branch morphology of the Galactic globular clusters ngc 6388 and NGC 6441 : new insights from UV observations
Context. In this paper we present multiband optical and UV Hubble Space Telescope photometry of the two Galactic globular clusters NGC 6388 and NGC 6441. Aims. We investigate the properties ofExpand
On a new parameter to estimate the helium content in old stellar systems
We introduce a new parameter Δξ—the difference in magnitude between the red giant branch (RGB) bump and the point on the main sequence (MS) at the same color as the bump (which we call theExpand
The Stellar Abundances for Galactic Archaeology (SAGA) data base - II. Implications for mixing and nucleosynthesis in extremely metal-poor stars and chemical enrichment of the Galaxy
We discuss the characteristics of known extremely metal-poor (EMP) stars in the Galaxy using the Stellar Abundances for Galactic Archaeology (SAGA) database (Suda et al. 2008, PASJ, 60, 1159). TheExpand
Early-Age Evolution of the Milky Way Related by Extremely Metal-Poor Stars
We exploit the recent observations of extremely metal-poor (EMP) stars in the Galactic halo and investigate the constraints on the initial mass function (IMF) of the stellar population that leftExpand

Rotations and Abundances of Blue Horizontal-Branch Stars in Globular Cluster M15.
TLDR
High-resolution optical spectra of 18 blue horizontal-branch stars in the globular cluster M15 indicate that their stellar rotation rates and photospheric compositions vary strongly as a function of effective temperature, and see evidence for faster stellar rotation explicitly preventing the onset of the diffusion mechanisms among a subset of the hotter stars.
