Title: Observations of the Chemical Abundances of Metal-Poor Stars and their Connection to the Pop III IMF Author(s): Anna Frebel Abstract: The chemical evolution of the Galaxy and the early Universe is a key topic in modern astrophysics. Since the most metal-poor Galactic stars are the local equivalent of the high-redshift Universe, they can be employed to reconstruct the onset of the chemical and dynamical formation processes of the Galaxy, the origin and evolution of the elements, and associated nucleosynthesis processes. They also provide constraints on the nature of the first stars and SNe, the initial mass function, and early star formation processes. I will discuss that the two most iron-poor objects as well as the new discoveries of extremely metal-poor stars in small dwarf galaxies are prime candidates to study the elusive first stars and their nucleosynthetic yields.
