"The Halo System of the Milky Way and the CEMP Stars Connection"
Abstract. Carbon Enhanced Metal Poor stars (CEMPs) have been recognized to be an important stellar component of the halo system of the Milky Way. They contain crucial information on the nature of the nucleosynthesis in the early Galaxy. In this talk I will discuss the general properties of the CEMP stars and their importance in Near Field Cosmology. I will also summarize the current view of the nature of the Galactic stellar halo, which comprises at least an inner- and an outer-halo population, each with different kinematics, spatial distributions, and chemistry, as confirmed both from recent observations and numerical galaxy formation scenarios. These smooth halo components exhibit also a distinct chemical pattern in term of fraction of CEMP stars. Such characteristics will be discussed during this talk together with possible formation scenarios of the halo system.
