1. Search for very metal-poor stars based on carbon over-abundance / Busca por estrelas muito pobres em metais baseada no enriquecimento em carbono
The main goal of this work is to show that is possible to search for metal-poor stars based on the premise that a large fraction of these will be carbon-rich. This hypothesis had not yet been verified because many of the so-called CEMP (Carbon Enhanced Metal-Poor) stars were neglected in previous studies due to the design of the search for metal-poor stars w
