Description
Nuclear astrophysics is an interdisciplinary field and this makes it so fascinating, but also renders the communications between different fields. We would like to introduce a seminar series with the goal of sharing knowledge and vocabulary among nuclear physicists, astrophysicists, and observers in an open atmosphere full of discussions and questions.
A dedicated interdisciplinary seminar on these topics does not exist in the Darmstadt-Frankfurt-Mainz-Giessen-Heidelberg-Bonn region. However, we are aware about the large number of seminars and colloquia around, therefore this nuclear astrophysics seminar will take place only once per month and be advertised broadly.
Since some of the people would have to travel we will have two talks  (starting at 16:00) with the possibility of going for dinner together and continue the discussions.
We really think these kind of seminars can foster future collaborations in the region.

      R. Stancliffe (University of Bonn): Modelling carbon-enhanced metal-poor stars

      A surprisingly large fraction of metal-poor stars are found to be
      carbon-rich. In addition, many of these display enhancements of neutron
      capture elements which give clues to their origin. I will discuss what
      we think we know about these so-called carbon-enhanced metal-poor (CEMP)
      stars, with a focus on those that display barium enrichments. These
      CEMP stars are thought to be formed in binary star systems that formerly
      contained an asymptotic giant branch (AGB) star, which polluted its
      companion through mass transfer. I will review our picture of AGB
      nucleosynthesis at low metallicity, how we think mass transfer happens
      and what happens to material once it is accreted by the secondary. This
      will highlight the problems we have when we try to confront observed
      CEMP star abundances with predictions from increasingly detailed stellar
      models.

      P. Woods (University of Edinburgh): Experiments for Explosive Nuclear Astrophysics

      Explosive astrophysical scenarios such as novae, X-ray bursts and supernovae
      require input on the properties and reactions of unstable nuclei. These influence the pathways of nucleosynthesis, observed elemental abundances, and energy generation. A variety of imaginative and interlocking experimental
      techniques are being developed to address this challenge. These will be described
      in the presentation.
