Chemical Abundances and Yields from Massive Stars
Stellar rotation produces an internal mixing of the elements due to shear instability and meridional circulation. This leads to observable N/C enhancements in massive stars above about 7–9 M⊙. Rotation also favours mass loss by stellar winds. Mass loss effects dominate for masses above 30 M⊙, while mixing dominates below that limit. The effects of mixing are also much larger at lower metallicit...
متن کاملChemical abundances from Magellanic cloud B stars
In recent years, B stars have been established as reliable tracers of present day abundance patterns. They yield an independent set of abundances from He to Fe which can be cross-checked against other sources such as H ii regions and cool supergiants. In this paper, we present purely spectroscopic analyses of 9 non-supergiant B stars (13 < mV < 15), 5 of which located in the young populous clus...
متن کاملAbundances and Kinematics of Field Stars II: Kinematics and Abundance Relationships
As an investigation of the origin of “α-poor” halo stars, we analyze kinematic and abundance data for 73 intermediate metallicity stars (−1 > [Fe/H] ≥ −2) selected from Paper I of this series. We find evidence for a connection between the kinematics and the enhancement of certain element-to-iron ([X/Fe]) ratios in these stars. Statistically significant correlations were found between [X/Fe] and...
متن کاملON omega CENTAURI AND ITS RRc STARS
Masses, temperatures, and absolute luminosities are proposed for a large sample of RRc stars in the globular cluster w Centauri. Our technique uses three observed quantities: period, relative luminosity, and Fourier phase CP31' interpreting them in the light of linear and hydrodynamic pulsation models. The masses we obtain agree with those of the RRd stars in other clusters, and our derived par...
متن کاملChemical abundances in cool metal rich disk dwarf stars
The present study of spectra of twelve metal-rich cool dwarf stars, carefully selected in order to cover a range of temperatures (∼ 4400 − 6000 K), is a follow up on Feltzing & Gustafsson (1998) with the aim to understand the apparent over-ionization and anomalous elemental abundances found by them for the K dwarf stars in their sample. Our method of analysis employs synthetic spectra of the fu...
