    • Abundances of carbon-enhanced metal-poor stars as constraints on their formation 

      Hansen, C.J.; Nordström, B.; Hansen, T.T.; Kennedy, C.R.; Placco, V.M.; Beers, T.C.; Andersen, J.; Cescutti, Gabriele; Chiappini, Cristina (2016-04-01)
      Context. An increasing fraction of carbon-enhanced metal-poor (CEMP) stars is found as their iron abundance, [Fe/H], decreases below [Fe/H] =−2.0. The CEMP-s stars have the highest absolute carbon abundances, [C/H], and ...

    • Chemodynamical simulations of the Milky Way Galaxy 

      Kobayashi, Chiaki (Cambridge University Press, 2009)
      We simulate the chemodynamical evolution of the Milky Way Galaxy, including the nucleosynthesis yields of hypernovae and a new progenitor model for Type la Supernovae (SNe la). In our nucleosynthesis yields of core-collapse ...

    • H I in galactic disks 

      Brinks, E.; Bigiel, Frank; Leroy, Adam; Walter, Fabian; de Blok, W. J. G.; Bagetakos, Ioannis; Usero, Antonio; Kennicutt, Robert C. (Cambridge University Press, 2009)
      Studies of the atomic phase of the interstellar medium, via the 21-cm spectral line of neutral hydrogen (H I), play a key role in our attempts to understand the structure and evolution of disk galaxies. We present here ...
