Rotation Velocities of Hot Horizontal Branch Stars in the Globular Clusters Ngc 1904, Ngc 2808, Ngc 6093, and Ngc 7078: the Database
We present radial and rotation (vsini) velocity measurements, from UVES+VLT high resolution spectra of 61 stars in the blue horizontal branches (HB) of the Galactic globular clusters NGC 1904 (M79), NGC 2808, NGC 6093 (M80), and NGC 7078 (M15). The data reduction and the velocity determination, based on cross-correlation techniques, are discussed in detail. Most of this database has been used b...
متن کاملThe White Dwarf Cooling Sequence in Ngc 6791
In the old, populous, and metal-rich open cluster NGC 6791 we have used deep HST/ACS images to track the white dwarf cooling sequence down to mF606W ≃ 28.5. The white dwarf luminosity function shows a well defined peak atmF606W ≃ 27.4, and a bending to the blue in the color–magnitude diagram. If this peak corresponds to the end of the white dwarf cooling sequence the comparison with theoretical...
متن کاملPhysical Parameters of Hot Horizontal-Branch Stars in NGC 6752: Deep Mixing and Radiative Levitation
Atmospheric parameters (Teff , log g and log nHe nH ) are derived for 42 hot horizontal branch (HB) stars in the globular cluster NGC6752. For 19 stars Mg II and Fe II lines are detected indicating an iron enrichment by a factor 50 on average with respect to the cluster abundance whereas the magnesium abundances are consistent with the cluster metallicity. This finding adds to the growing evide...
متن کاملSe p 20 03 Helium - rich EHB Stars in Globular Clusters ∗
Recent UV observations of the most massive Galactic globular clusters show a significant population of hot stars below the zero-age HB (“blue hook” stars), which cannot be explained by canonical stellar evolution. Stars which suffer unusually large mass loss on the red giant branch and thus experience the heliumcore flash while descending the white dwarf cooling curve could populate this region...
متن کاملWhite dwarf atmosphere models with Ly - α opacity in the analysis of the white dwarf cooling sequence of NGC 6397
Aims. We discuss the importance of pure hydrogen white dwarf atmosphere models with Ly-α far red wing opacity in the analysis of the white dwarf cooling sequence of the globular cluster NGC 6397. Methods. Our recently improved atmosphere models account for the previously missing opacity from the Ly-α hydrogen line broadened by collisions of the absorbing hydrogen atoms with molecular and atomic...
