    • The Binary Frequency Among Carbon-enhanced, s-Process-rich, Metal-poor Stars 

      Lucatello, S.; Tsangarides, S.; Beers, T.C.; Carretta, E.; Gratton, R.G.; Ryan, Sean G. (2005)
      We discuss radial velocities for a sample of carbon-enhanced, s-process–rich, very metal-poor (CEMP-s) stars, analyzed with high-resolution spectroscopy obtained over multiple epochs. We find that ~68% of the stars in the ...
