Resumen:
We present a new semi-empirical model of theatmosphere of the widely studied K-dwarf EpsilonEridani (HD 22049). The model is build toreproduce the visible spectral observations from3800 to 6800 ̊, and A the h and k Mg IIlines profiles. The computations were carriedout using the Solar-Stellar Radiation PhysicalModeling (SSRPM) tools, which calculate non-LTEpopulation for the most important species in thestellar atmosphere. We show a comparison betweenthe synthetic and observed spectrum, obtaining agood agreementin all the studied spectral range.
