  • Carbon-Enhanced Metal-Poor Stars in SDSS/Segue. I. Carbon Abundance Estimation and Frequency of CEMP Star 
    Lee, Y. S; Beers, T. C; Masseron, T; Plez, B; Rockosi, C. M; Sobeck, J; Yanny, B; Lucatello, S; Sivarani, T; Placco, V. M; Carollo, D (IOP Publishing, 2013-11)
    We describe a method for the determination of stellar [C/Fe] abundance ratios using low-resolution (R = 2000) stellar spectra from the Sloan Digital Sky Survey (SDSS) and its Galactic sub-survey, the Sloan Extension for ...
  • The Case for the Dual Halo of the Milky Way 
    Beers, T. C; Carollo, D; Ivezic, Z; An, D; Chiba, M; Norris, J. E; Freeman, K. C; Lee, Young Sun; Munn, J. F; Re Fiorentin, P; Sivarani, T; Wilhelm, R; Yanny, B; York, D. G (IOP Publishing, 2012-02-10)
    Carollo et al. have recently resolved the stellar population of the Milky Way halo into at least two distinct components, an inner halo and an outer halo. This result has been criticized by Schönrich et al., who claim that ...

    The Sloan Digital Sky Survey (SDSS) started a new phase in 2008 August, with new instrumentation and new surveys focused on Galactic structure and chemical evolution, measurements of the baryon oscillation feature in the ...
