      Possible main formation sites of F in the Universe include AGB stars, the {\nu}-process in Type II SNe, and/or W-R stars. The importance of the W-R stars has theoretically been questioned and they are probably not needed ...

      Thousands of exoplanets have now been discovered with a huge range of masses, sizes and orbits: from rocky Earth-like planets to large gas giants grazing the surface of their host star. However, the essential nature of ...

    • Chemical warfare: the fungal quest to conquer oilseed rape

    • Chemically consistent evolutionary synthesis 

      Fritze, U.; Weilbacher, P.; Bicker, J. (2003)
      To account for the range of stellar metallicities in local galaxies and for the increasing importance of low metallicities at higher redshift we present chemically consistent models for the spectral and chemical evolution ...

    • Chemistry of heavy elements in the Dark Ages 

      Vonlanthen, P.; Rauscher, T.; Winteler, C.; Puy, D.; Signore, M.; Dubrovich, V. (2009-08)
      Context. Primordial molecules were formed during the Dark Ages, i.e. the time between recombination and reionization in the early Universe. They were the constituents of the first proto-stellar clouds. Standard Big Bang ...

    • Chemistry of Molecular Gas in Starbursts and AGN 

      Garcia-Burillo, S.; Fuente, A.; Usero, A.; Martin-Pintado, J. (Astronomical Society of the Pacific, 2004)
      We present the main results of an extragalactic survey aiming to study the chemistry of molecular gas in a limited sample of starburst galaxies (SB) and AGN hosts. Observations have been carried out with the IRAM 30m ...

    • Chemo-Dynamical Evolution of Galaxies 

      Kobayashi, Chiaki; Taylor, Philip (Springer Nature, 2023-02-17)
      Stars are fossils that retain the history of their host galaxies. Elements heavier than helium are created inside stars and are ejected when they die. From the spatial distribution of elements in galaxies, it is therefore ...

    • Chemo-dynamical Simulations and Galactic Archaeology 

      Kobayashi, Chiaki (American Institute of Physics (AIP), 2010)
