Are the Bulge C – stars related to the Sagittarius dwarf galaxy? II. Metallicity – a link with the galactic disc
The photometric estimate of the metallicity and the age of the Azzopardi et al. (1991) carbon stars (Ng 1997) is revised to respectively Z ' 0.004 and ∼ 0.1 Gyr. Under the hypothesis that the carbon stars are located at a distance related to the Sagittarius dwarf galaxy, the broad velocity dispersion of the stars can only be explained if they were formed out of Galactic material during a recent...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولFurther Evidence for a Merger Origin for the Thick Disk: Galactic Stars Along Lines-of-sight to Dwarf Spheroidal Galaxies
The history of the Milky Way Galaxy is written in the properties of its stellar populations. Here we analyse stars observed as part of surveys of local dwarf spheroidal galaxies, but which from their kinematics are highly probable to be non-members. The selection function – designed to target metal-poor giants in the dwarf galaxies, at distances of ∼ 100 kpc – includes F-M dwarfs in the Milky W...
متن کاملThe Metallicity of Stars with Close Companions
We examine the relationship between the frequency of close companions (stellar and planetary companions with orbital periods<5 yr) and the metallicity of their Sun-like ( FGK) hosts. We confirm and quantify a 4 positive correlation between host metallicity and planetary companions. We find little or no dependence on spectral type or distance in this correlation. In contrast to the metallicity d...
متن کاملEvolution and colours of helium-core white dwarf stars: the case of low metallicity progenitors
The present work is designed to explore the evolution of helium-core white dwarf (He WD) stars for the case of metallicities much lower than the solar metallicity (Z= 0.001 and Z= 0.0002). Evolution is followed in a self-consistent way with the predictions of detailed and new non-grey model atmospheres, time-dependent element diffusion and the history of the white dwarf progenitor. Reliable ini...
