Late-type stars are the most abundant in the galactic stellar population.These stars, with a similar internal structure to the Sun, are expected to havesolar-like atmospheres. Investigating the stellar parameters and chemicalabundances on late-type stars is essential to provide valuable constraintsabout stellar age, chemical evolution, and atmosphere of exoplanets. In thiswork, we present the study of the Near-UV and optical spectroscopic observationof three late-type stars: HR 8038, AC Her, and HD 76446, as obtained from the36-inch MIRA/Oliver Observing Station. We derived surface temperature, gravity,metallicity, and the chemical abundances of light element Carbon in the stellaratmosphere. The elemental abundance of the Carbon for HR 8038, AC Her, and HD76446 are derived to be 95%, 97%, and 108%, respectively, of the solar value.
