The Dichotomy of the Halo of the Milky Way
Daniela Carollo, Timothy C. Beers
We summarize evidence that the halo of the Milky Way comprises two different, and broadly overlapping, stellar components. The two structures exhibit different chemical composition…
Carbon-Enhanced Metal-Poor Stars. III. Main-Sequence Turn-Off Stars from the SDSS/SEGUE Sample
Wako Aoki, Timothy C. Beers, Thirupathi Sivarani +6
The chemical compositions of seven Carbon-Enhanced Metal-Poor (CEMP) turn-off stars are determined from high-resolution spectroscopy. Five of them are selected from the SDSS/SEGUE…
Two Stellar Components in the Halo of the Milky Way
D. Carollo, T. C. Beers, Y. S. Lee +9
The halo of the Milky Way provides unique elemental abundance and kinematic information on the first objects to form in the Universe, which can be used to tightly constrain models…
The GSC-II-based survey of ancient cool white dwarfs I. The sample of spectroscopically confirmed WDs
D. Carollo, B. Bucciarelli, S. T. Hodgkin +6
The GSC-II white dwarf survey was designed to identify faint and high proper motion objects, which we used to define a new and independent sample of cool white dwarfs. With this su…
Disk or Halo white dwarfs? Kinematic analysis of high proper motion surveys
A. Spagna, D. Carollo, M. G. Lattanzi +1
We present an alternative method for the kinematic analysis of high proper motion surveys and discuss its application to the survey of Oppenheimer et al. (2001) for the selection o…
Model atmosphere analysis of the extreme DQ white dwarf GSC2U J131147.2+292348
D. Carollo, D. Koester, A. Spagna +2
A new model atmosphere analysis for the peculiar DQ white dwarf discovered by Carollo et al. (2002) is presented. The effective temperature and carbon abundance have been estimated…
