Descripción
We have been analyzing a large sample of solar-like stars with and
without planets in order to homogeneously measure their photospheric
parameters and Carbon abundances. Our sample contains around 200 stars
in the solar neighborhood observed with the ELODIE spectrograph, for
which the observational data are publicly available. We performed
spectral synthesis of prominent bands of C2 and CI lines,
aiming to accurately obtain the C abundances. We intend to contribute
homogeneous results to studies that compare elemental abundances in
stars with and without known planets. New arguments will be brought
forward to the discussion of possible chemical anomalies that have been
suggested in the literature, leading us to a better understanding of the
planetary formation process. In this work we focus on the C abundances
in both stellar groups of our sample.
