The Quest for the Most Metal-Poor Stars:
From Ongoing to Future Surveys Norbert Christlieb University of Hamburg, Germany abstract Extremely metal-poor stars are an important tool for studying, among other things, the formation and chemical evolution of the Galaxy, the properties of the first generation of massive stars exploding as type II supernovae, and nucleosynthesis processes occurring in them. I will review the current status of the search for the most metal-poor stars and give an overview of what are in my opinion the most important problems of the field. I will conclude with an outlook on what might possibly be achieved with future surveys, the next generation of large telescopes, dedicated and specialized small telescopes, and future space missions. |
